Selecting the right electrical components is the heartbeat of refrigeration maintenance. When a compressor fails to start or constantly trips, the culprit is often a mismatched Current Relay or a fatigued Thermal Overload Protector. Ensuring these parts align perfectly with the compressor’s horsepower (HP) and amperage rating is not just about repair—it is about system longevity.
The Role of Current Relays in Compressor Ignition
Current relays are electromagnetic switches that momentarily engage the start winding of a compressor. Once the motor reaches approximately 75% of its rated speed, the relay disconnects the start winding, allowing the motor to run on its main winding.

Thermal Overload Protectors: The Safety Net
Thermal Overload Protectors (TOP) act as a bimetallic fuse. They monitor both the heat generated by the compressor and the current flowing through it. If the compressor stalls (locked rotor) or overheats due to a refrigerant leak, the TOP breaks the circuit to prevent the motor windings from melting.

Comparison: Mechanical Relays vs. PTC Starters
While the technical data above focuses on mechanical current relays, modern systems often use PTC (Positive Temperature Coefficient) starters.
Mechanical Relays (117U Series): Highly reliable for heavy-duty applications. They provide a “snap” action that is better for high-torque starts.
PTC Starters: Use a solid-state disk that increases resistance as it heats up. They are quieter but require a cool-down period before the compressor can restart.
Engineering Advice for Field Technicians
Never Oversize the Protector: If you install a 1/2 HP protector on a 1/6 HP compressor, the protector will not trip during a fault, leading to a burnt-out compressor.
Check the Return Temperature: Thermal caps must operate within a return temperature range of 60 ± 10°C. Anything higher indicates a system restriction or lack of airflow over the condenser.
Terminal Integrity: Ensure terminals are tight. A loose connection creates resistance, which generates heat and causes “nuisance tripping” of the overload.

Excerpt: The Matsushita QA77C17GAX5 is a workhorse in the refrigeration world. This 1/4 HP R134a compressor is a go-to for many household fridges and freezers. In this guide, we break down the technical specs, electrical wiring, and the most reliable replacement options to help you get your cooling system back up and running fast.
The Technician’s Take on the Matsushita QA77C17GAX5
When you spend enough time in the field, you start to recognize certain parts that just don’t quit. The Matsushita QA77C17GAX5 is one of those units. Produced by Panasonic, this compressor has been a standard in residential cooling for years. It’s a 1/4 HP unit designed for Low Back Pressure (LBP) applications, meaning it’s built to reach and hold those deep-freeze temperatures.
What makes this model interesting is its balance. It has a 7.7cc displacement, which is a sweet spot for R134a systems. It’s powerful enough for a full-sized family refrigerator but efficient enough that it doesn’t hammer the electric bill. From an engineering perspective, the RSIR motor is simple and reliable—fewer components like capacitors mean fewer things to fail in the heat of summer.
Real-World Performance
I’ve noticed that these compressors handle voltage dips better than many modern counterparts. While some high-efficiency units are sensitive to “dirty” power, the QA77 series is built like a tank. It delivers about 180 Watts of cooling power at standard ASHRAE conditions, making it a versatile choice for a wide range of kitchen appliances.

Wiring and Electrical Logic
Working with the electrics on this unit is straightforward. It uses a three-pin terminal setup.
Top Pin (Common): This is where your Overload Protector (OLP) sits. It’s the safety gate that shuts the compressor down if it gets too hot.
Bottom Left/Right (Start & Run): The PTC relay slides onto these. When you power it up, the relay gives a quick “kick” to the Start winding and then lets the Run winding take over once the motor is spinning.
Pro Tip: If the compressor won’t start but it’s humming, check the PTC relay first. They often burn out before the motor does. Shake it—if it rattles like broken glass, it’s shot.

Expert Maintenance Notice
Vacuum is Non-Negotiable: Because this unit uses POE oil, moisture is the enemy. POE oil absorbs water from the air, which creates acid inside the system. You must pull a deep vacuum before charging.
Filter Drier: Don’t be lazy—always swap the filter drier when you open the system. It’s the cheapest insurance policy you can buy for a new compressor.
Oil Warning: Never add mineral oil to this system. It will not mix with R134a and will eventually cause a blockage or mechanical failure.

Professional Replacement & Cross-Referencing
Finding a replacement for an inverter unit requires matching the displacement and the inverter board’s drive signal.
5 Compressor Replacements (Same Gas: R600a)
LG BSA075NHMV: A common alternative within the LG ecosystem.
Samsung MSV4A1A-L1B: A very close match in displacement and performance.
Embraco FMXA9C: High-end variable speed unit for R600a.

Panasonic QB77C16GPX5: Highly reliable for LBP R134a systems.
Embraco EMY70HLC: A standard LBP alternative (requires inverter-to-standard conversion).
Engineering Insights & Safety Guidelines
R600a Safety: Because R600a is flammable, always use a dedicated recovery machine and avoid open flames. I recommend using the braze-free “Lokring” method for connections to maintain safety in residential environments.
The “LG Drive Only” Warning: This compressor is strictly designed for LG’s specific inverter drive logic. Attempting to power this with a standard 220V AC source will immediately destroy the internal BLDC windings.
Winding Integrity: When testing, measure resistance across the three terminals (U, V, W). You should see balanced resistance. Any “Open” or “Short” indicates a terminal failure.
Oil Management: The BR1MOIL is highly sensitive to moisture. Ensure the system is under vacuum for at least 30 minutes before charging to remove all non-condensables.
Final Maintenance Advice
To get the most out of the LG FMA102NAMA, keep the condenser coils free of dust. Inverter compressors work harder when they can’t shed heat, leading the controller to “throttle” the speed, which results in poor cooling despite the compressor technically running.
The Bottom Line: The LG FMA102NAMA is a precision instrument. Treat it with the technical respect it deserves, and it will provide years of silent, efficient service.
echnical Deep Dive: The LG FMA102NAMA Inverter Compressor mbsmpro
Over my decades in the refrigeration trenches, I have seen the industry shift from robust, “clunky” fixed-speed pumps to the sophisticated whispering of variable-capacity units. When I walk up to a modern high-end residential refrigerator and hear that signature high-pitched ramp-up, I know I am likely dealing with an Embraco FMXY9C. These “Fullmotion” inverter compressors are the gold standard for energy efficiency today, but for many technicians, they remain a “black box” of mystery. If the cabinet is warm and you don’t hear that specific harmonic hum, you are likely looking at a complex dance between the inverter control board and the compressor windings.
Mastering the FMXY9C: The Engineer’s Technical Breakdown
The FMXY9C is not your grandfather’s compressor. As a Senior Engineer, I categorize this as a Variable Capacity Compressor (VCC). Unlike standard units that are either “On” or “Off,” this unit varies its speed between 43Hz and 134Hz. This allows the refrigerator to maintain a near-constant temperature without the massive energy spikes associated with traditional startup cycles.

The Engineer’s Secret: Diagnostic Logic for Inverter Systems
In my experience, the most common mistake field workers make is trying to “jump-start” this compressor directly from a wall outlet. Do not do this. You will instantly destroy the permanent magnet motor.
To diagnose a suspected FMXY9C failure, I follow this non-negotiable protocol:
The Resistance Equilibrium: Disconnect the three-pin plug. Measure the resistance between all three pins (U, V, W). You should find near-identical readings (typically between 10 to 16 ohms depending on ambient temp). If one leg is “open” or significantly higher, the compressor is dead.
The Inverter Signal Test: If the windings are balanced, the fault usually lies in the Embraco Control Unit. Check for the DC signal from the main logic board to the inverter. If the control board isn’t sending the “frequency command,” the compressor will never ramp up.
The R600a Warning: This unit uses Isobutane. I always use a “No-Flame” approach (Locring or high-quality compression fittings) unless I have a fully purged environment. Isobutane is highly flammable, and safety is paramount when opening these systems.

5 Technical Alternatives (Different Gas/Type – Major Retrofit Required)
Warning: These require changing the control board and refrigerant circuit.
Embraco VEGY 8H (R134a Inverter)
Secop NLE15KTK (R290 – High efficiency but different pressure)
Vacuum Depth: Because R600a systems use very small charges (often less than 60g), moisture is a system-killer. I never stop until my micron gauge hits 250 microns.
Filter Drier: Always use a drier specifically rated for R600a. Standard R134a driers may have desiccant that reacts poorly with isobutane over long periods.
Charging Precision: Do not charge by pressure. You must use a digital scale accurate to 1 gram. A 5-gram error is enough to cause evaporator flood-back or poor cooling performance.
Question: Can I use a regular start relay on the FMXY9C for testing? Answer: Absolutely not. This compressor requires a pulsed 3-phase signal generated by the inverter control unit. Applying 230V AC directly to the pins will result in permanent internal damage to the windings and the magnetic rotor.

not recommended to replace compressor (Jiaxipera N1113Y) with (ACC HTK70AA).
Category: Refrigeration
written by www.mbsmpro.com | January 29, 2026
Based on the technical specifications of both compressors, it is not recommended to replace the burnt-out compressor (Jiaxipera N1113Y) with the second one (ACC HTK70AA).
Here is the technical comparison:
1. The Original Compressor (Jiaxipera N1113Y)
Displacement: 8.9 cm³
Cooling Capacity: Approximately 154 Watts
Horsepower Equivalent: Roughly 1/6 HP
Gas Type: R600a
2. The Replacement Compressor (ACC HTK70AA)
Displacement: 6.64 cm³
Cooling Capacity: Approximately 117 Watts
Horsepower Equivalent: Roughly 1/8 HP
Gas Type: R600a
Why this is a bad match:
While both compressors use the same refrigerant (R600a) and voltage (220-240V), the ACC HTK70AA is significantly weaker than the original Jiaxipera.
If you install it, the following problems will occur:
Poor Cooling: The fridge will take a very long time to get cold, and it may never reach the desired temperature, especially in hot weather.
Continuous Running: Because the compressor is undersized, it will stay “on” almost all the time to try to cool the unit.
Short Lifespan: Working continuously will cause the replacement compressor to overheat, leading to a very short life before it burns out as well.
Conclusion:
You should look for a replacement compressor that has a cooling capacity of around 150–160 Watts or a displacement of 8.9 cm³ (equivalent to 1/6 HP). Using the 1/8 HP compressor (the ACC model) will likely result in a failed repair.

Meta Description: Detailed technical review of the Jiaxipera N1113Y and ACC HTK70AA compressors. Learn why cooling capacity and displacement matter more than just the refrigerant type when performing a replacement.
Excerpt: Selecting the right compressor for a refrigeration system is critical for long-term performance and energy efficiency. When replacing a Jiaxipera N1113Y, simply matching the refrigerant type is not enough. This guide breaks down the technical differences between the N1113Y and the ACC HTK70AA, providing the essential data for professional technicians and refrigeration engineers.
Technical Article: The Engineering Reality of Compressor Sizing
In the field of refrigeration, a compressor is the heart of the system. For an expert technician, replacing a unit isn’t just about finding a motor that fits the mounting bracket; it is a calculation of thermal dynamics. A common question arises when a Jiaxipera N1113Y fails: Can an ACC HTK70AA serve as a reliable substitute?
The short answer is no. To understand why, we must look at the displacement and the cooling capacity (Watts). The Jiaxipera N1113Y is a powerhouse in its class, designed for medium-to-large domestic refrigerators. It features a displacement of 8.9 cm³ and delivers approximately 154 Watts of cooling at Low Back Pressure (LBP) conditions.
In contrast, the ACC HTK70AA is a smaller unit. With a displacement of only 6.64 cm³, it produces around 117 Watts. When an undersized compressor like the HTK70AA is installed in a system designed for a 154W load, the compressor will run continuously, overheat, and eventually experience mechanical failure or winding burnout.

Why “Close Enough” Isn’t Good Enough
When you install a 1/8 HP compressor where a 1/6 HP unit is required, the internal pressures of the refrigeration cycle change. The suction pressure will remain higher than intended because the smaller piston cannot evacuate the evaporator quickly enough. This leads to poor frost patterns and higher cabinet temperatures, especially during high ambient summer conditions.

Match the Displacement: Never go more than 10% lower in cm³ displacement.
Vacuuming: R600a systems are extremely sensitive to moisture. A deep vacuum (below 500 microns) is mandatory.
Safety First: R600a is flammable. Ensure no open flames or sparks are present during the charging process.
Question: If I have a 350-liter fridge, will the ACC HTK70AA work? Answer: No. A 350-liter refrigerator typically requires the 154W capacity of the Jiaxipera N1113Y (1/6 HP). The ACC HTK70AA (1/8 HP) is designed for smaller units (around 150-220 liters). Using it will lead to continuous running and premature failure.
our decision to stay away from these four brands (Kriazi, Candy, GMC, White Whale) may be based on past experiences or technical advice related to the availability of spare parts, the quality of after-sales service, or the lifespan of electronic components.
In the professional appliance sector, choosing a washing machine is an engineering audit, not a simple shopping trip. As a field expert who has dismantled thousands of units and performed rigorous stress tests on drive systems, I look beyond the digital displays to the mechanical heart of the machine: the drum bearings, the motor windings, and the electrolytic capacitors on the control board.
Technical data from the field indicates a significant divergence in quality. While some brands focus on high-turnover consumer goods, others invest in Structural Integrity. If you are being advised to “stay away” from Kiryazi, Candy, GMC, and White Whale, it is not a matter of brand bias—it is a matter of documented mechanical fatigue and specialized component scarcity.
Technical Breakdown: Identifying the Structural Bottlenecks
When an appliance fails, it is usually due to a “weakest link” in its design. Here is the professional technical breakdown of why these four brands often face professional criticism from repair engineers:
Kiryazi (Structural Oxidation): The primary issue lies in the galvanization process of the outer cabinet. In many models, the steel gauge is insufficient, leading to premature rust around the detergent drawer and base, which eventually compromises the machine’s balance during high-RPM cycles.
Candy (Electronic Volatility): Candy machines often feature highly sophisticated integrated circuits. However, the PCB (Printed Circuit Board) lacks robust thermal shielding. In environments with fluctuating voltage, the microprocessor is prone to “logic hanging” or total failure.
GMC (Mechanical Friction): Many GMC models rely on traditional Universal Brush Motors. These motors generate significant carbon dust and heat, leading to shorter lifespans for the drive belt and much higher decibel levels during the spin cycle.
White Whale (Component Inconsistency): The “Spider” assembly (the three-arm support for the drum) in these units is frequently made of a low-grade Zinc-Aluminum alloy. This material reacts chemically with liquid detergents, leading to “pitting corrosion” and eventual drum detachment.
Engineering Comparison: High-Tier vs. Standard Tier
To make an informed decision, we must compare the Material Science and Drive Systems of industry leaders against standard budget models.

The Inverter Logic: Electronic Schematic of Superiority
For the technician, the shift to Inverter Technology (found in LG, Samsung, and Bosch) is the greatest leap in reliability. Unlike the simple “On/Off” relay logic of older GMC or Kiryazi units, modern systems utilize a Variable Frequency Drive (VFD) logic path:
Rectification Stage: Incoming AC is converted to stable DC power.
IGBT Switching: (Insulated Gate Bipolar Transistors) pulse the power to the motor windings.
Frequency Modulation: By changing the electrical frequency, the machine controls torque and speed with extreme precision, without mechanical stress.
Result: This eliminates the Carbon Brushes, which are the primary wear-and-tear component in traditional washing machines.

Professional Councils and Maintenance Protocols
Advice on Installation: Never place a washing machine on a wooden floor or an unlevel surface. For Bosch and LG units, precision leveling is required to allow the internal accelerometers to calibrate the “Zero-Point” vibration correctly.
Notice on Detergent: Excessive use of “Soap Powder” causes a buildup known as “Scrud.” In White Whale and Candy models, this acidic sludge accelerates the decay of the drum seal.
The Benefit of Direct Drive: By removing the belt, LG has eliminated a major friction point, significantly reducing energy loss and increasing the motor’s life expectancy to over a decade.
Final Technical Verdict
The recommendation to avoid Kiryazi, Candy, GMC, and White Whale is based on the Mean Time Between Failures (MTBF) observed in the field. As an engineer, I recommend prioritizing brands that utilize Resin-Encapsulated Electronics and Brushless Motors. LG, Samsung, and Bosch provide the necessary Mechanical Tolerance to handle the stresses of modern laundry requirements.

I charged the compressor CAJ4519Z with R407 gas, and upon startup, some frost appeared on the return line and expansion valve, even though the cooling was fine. Is this normal? Note that it’s a refrigeration room, not a freezer.
Category: Refrigeration
written by www.mbsmpro.com | January 29, 2026
Regarding the compressor in the photo (Tecumseh CAJ4519Z) used in a cold room (chilling/positive temperature) with R-407C gas, finding frost on the suction line and the expansion valve is not normal for this type of application.
While the cooling might seem “good” now, frost on the suction line indicates that liquid refrigerant is not fully evaporating in the evaporator and is returning to the compressor.
Here is a technical breakdown of why this is happening and how to fix it:
1. Low Superheat (Expansion Valve Adjustment)
This is the most common cause. If the expansion valve is open too wide, it allows too much liquid into the evaporator.
The Risk: Liquid refrigerant can reach the compressor (Liquid Slugging), which can break the internal valves of the CAJ4519Z compressor.
The Fix: You need to adjust the Superheat. For a positive temperature cold room, the superheat should be between 5°C and 8°C. If it is lower, slightly close the expansion valve (turn the adjustment screw clockwise) in half-turn increments and wait 15–20 minutes to see the effect.
2. Overcharging the System
If you added too much R-407C, the excess refrigerant stays in the evaporator and suction line as a liquid/gas mix, causing frosting.
Note on R-407C: This is a “blend” refrigerant. It must always be charged in the liquid state (tank upside down). If you charged it as a vapor, the mixture ratio might be wrong, affecting performance.
The Fix: Check the sight glass (if available) and monitor the pressures. For R-407C in a cold room at 0°C to +4°C, your suction pressure should typically be around 45 to 55 PSI.
3. Poor Airflow at the Evaporator
If the heat exchange is poor, the refrigerant won’t boil off into a gas.
Check the Evaporator (EVACOND unit in your photo):
Are the fans spinning at the correct speed?
Are the fins dirty or clogged?
Is there already an ice buildup on the evaporator coils blocking the air?
4. Expansion Valve Sensing Bulb
Check the location of the expansion valve’s sensing bulb.
If the bulb is loose or not insulated properly, it “thinks” the pipe is warm and opens the valve too much, flooding the suction line.
The Fix: Ensure the bulb is tightly clamped to the suction pipe (at the 2 o’clock or 10 o’clock position) and well-insulated.
Summary Recommendation:
Frost should generally stop at the outlet of the expansion valve or the very beginning of the evaporator. If the frost is traveling all the way back to the compressor:
Slightly close the expansion valve.
Verify the airflow over the evaporator.
Ensure you haven’t overcharged the system.
Allowing frost to reach the compressor will eventually lead to mechanical failure or “slugging,” which will destroy the compressor.

Engineering Insights: Managing Frost and Superheat
In field operations, specifically when retrofitting or charging systems with R407C, technicians may encounter frost on the suction line. From an engineering perspective, frost migrating toward the compressor crankcase is a critical warning sign.
Diagnostic Checkpoint:
Superheat Calibration: For a positive temperature cold room, the target superheat at the evaporator outlet should be between 5K and 8K. If frost reaches the suction service valve, the superheat is likely near zero, risking liquid slugging.
R407C Glide: Unlike R404A, R407C has a significant temperature glide. Charging must be performed in the liquid phase to maintain the correct blend ratio.
Expansion Valve Tuning: If the cooling is effective but frosting occurs, the Thermostatic Expansion Valve (TXV) may be adjusted too “open.” Closing the valve (clockwise) increases superheat and retreats the frost line.
The CSR (Capacitor Start – Run) motor configuration is designed for high starting torque.
Common (C): Connected to the Overload Protector.
Start (S): Connected to the Potential Relay (Terminal 2) and Start Capacitor.
Run (R): Connected to the Main Power and Run Capacitor.
Potential Relay: Terminals 1 and 2 disconnect the start capacitor once the motor reaches ~75% speed.
Expert Advice and Notice
Notice: Always use a filter drier compatible with POE oil. POE is highly hygroscopic (absorbs moisture rapidly).
Benefit: The CAJ4519Z features an internal pressure relief valve, providing an extra layer of safety against system over-pressurization.
Engineering Tip: When using R407C, ensure the condenser is sized for the additional heat rejection requirements compared to R22. Failure to do so will result in high head pressures and reduced compressor lifespan.

From our professional experience, the compressor is small and has a maximum length of 10 feet.
In the specialized world of HVAC and domestic refrigeration, selecting the correct compressor is the difference between a long-lasting appliance and a premature mechanical failure. The ZMC EGM60AF stands out as a reliable workhorse in the Low Back Pressure (LBP) category. This hermetic reciprocating compressor is frequently utilized by major appliance manufacturers for its thermal efficiency and robust construction under varying environmental conditions.
Technical Engineering Analysis
The EGM60AF is a 1/6 HP unit optimized for R134a refrigerant. In my years as a field engineer, I have observed that this specific model strikes a balance between energy consumption and torque. Utilizing a Resistive Start Induction Run (RSIR) motor, it is designed for simplicity and durability. With a displacement of approximately 6.00 cc, it provides sufficient mass flow for standard household refrigerators ranging from 8 to 11 cubic feet.
Application and Sizing Logic
When retrofitting or repairing, field workers must exercise caution regarding cabinet size. While the EGM60AF is highly efficient, installing it in a large 14-cubic-foot unit—which typically demands a 1/5 or 1/4 HP motor—can lead to “short-cycling” or continuous operation. This results in overheating the motor windings and eventual mechanical seizure. For optimal performance, this compressor should be paired with a correctly sized capillary tube to ensure the evaporation temperature remains within the -30°C to -10°C range.

Start (S): Connected to the PTC Relay. The PTC relay provides a high resistance to the start winding once the motor reaches roughly 75% of its speed, effectively dropping the start winding out of the circuit.
Comparative Analysis: EGM60AF vs. EGL70AA
When comparing the 1/6 HP EGM60AF with the slightly larger 1/5 HP EGL70AA:
Cooling Power: The EGL70AA offers roughly 25% more BTU capacity, making it suitable for 14-foot fridges where the EGM60AF would struggle.
Energy Efficiency: The EGM60AF is superior in smaller cabinets due to lower wattage draw (approx. 110W vs 145W during stable run time).

Engineering Advice and Field Notices
Vacuuming: Always pull a vacuum down to 500 microns. Moisture in R134a systems reacts with Ester oil to form acid, which will corrode the motor windings.
Filter Drier: Never reuse a filter drier. Always replace with a new 15g or 20g molecular sieve drier when opening the system.
Heat Dissipation: Ensure the condenser coils are clean. The EGM60AF is designed for static cooling, but if the fridge is located in a high-ambient area (above 40°C), adding a small auxiliary fan near the compressor can significantly extend its life.
Conclusion: The ZMC EGM60AF remains a top choice for technicians looking for a reliable, “Made in Egypt” solution for standard household repairs. Its compatibility with R134a makes it a straightforward replacement for millions of units currently in service across the Middle East and Africa.

Performance Dynamics: Why the EGM60AF Packs a Punch
While both compressors are rated at 1/5 HP, the ZMC EGM60AF features a larger cylinder volume of 6.0cc compared to the 5.5cc of the Huayi model. This translates directly into a higher mass flow of refrigerant.
Key Differences in Field Performance:
Pull-Down Time: The EGM60AF typically achieves the set-point temperature faster in a 14-foot cabinet due to its higher BTU/h output.
Thermal Stability: With a 270 cm³ oil charge, the ZMC model offers superior lubrication and cooling for the internal mechanical parts, making it more resilient during long run cycles in summer.
Efficiency: The Huayi HYE55YL63 often runs at a lower amperage (approx. 0.7A) compared to the EGM60AF, making it the preferred choice for energy-sensitive applications where a lighter load is sufficient.

Expert Recommendations for the Field
As a field engineer who has handled hundreds of Kiriazi 14-foot units, I strongly advise the following during installation:
Capillary Matching: If upgrading from a 5.5cc to a 6.0cc compressor, ensure your capillary tube is not restricted. A slight increase in capacity may lead to higher discharge pressures if the condenser is not kept clean.
Capacitor Utility: The Huayi model performs best with a 3µF to 5µF run capacitor. This stabilizes the motor torque and protects the windings from “stalling” during hot restarts.
The Vacuum Rule: R134a systems are highly sensitive to moisture. Always pull a vacuum below 500 microns to prevent the POE/Ester oil from turning acidic, which will eventually eat through the copper windings.
