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:

1. 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.
2. Continuous Running: Because the compressor is undersized, it will stay “on” almost all the time to try to cool the unit.
3. 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.

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.

Comparative Analysis Table

Feature	Jiaxipera N1113Y	ACC HTK70AA	Impact of Difference
Displacement	8.9 cm³	6.64 cm³	Lower volume per stroke
Cooling Capacity	154 W (~1/6 HP)	117 W (~1/8 HP)	24% loss in cooling power
Current (LRA)	~7.5 A	~6.1 A	Different torque characteristics
Efficiency (COP)	High Efficiency	Standard Efficiency	Increased energy consumption

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.

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.

Mbsmpro.com, Washing Machines, Technical Reliability, LG, Samsung, Bosch, Structural Failures, Kiryazi, Candy, GMC, White Whale

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.

Technical Component	Standard Group (Avoid)	LG (Direct Drive)	Samsung (Inverter)	Bosch (Series 6/8)
Motor Tech	Universal Carbon Brush	Brushless DC (BLDC)	Digital Inverter	EcoSilence Drive
Drive Logic	Mechanical Pulley	Direct Coupling	Reinforced Ribbed Belt	High-Torque Belt
Bearing Seal	Single Lip	Double-Lip / Viton	High-Temp Synthetic	Industrial Grade
PCB Protection	Basic Varnish	Resin Encapsulation	Moisture Shield	Thermal Management
Vibration Control	Standard Springs	6-Motion AI	VRT Plus (Ball Balance)	AntiVibration Walls

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:

1. Rectification Stage: Incoming AC is converted to stable DC power.
2. IGBT Switching: (Insulated Gate Bipolar Transistors) pulse the power to the motor windings.
3. Frequency Modulation: By changing the electrical frequency, the machine controls torque and speed with extreme precision, without mechanical stress.
4. 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.

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:

1. Slightly close the expansion valve.
2. Verify the airflow over the evaporator.
3. 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:

1. 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.
2. R407C Glide: Unlike R404A, R407C has a significant temperature glide. Charging must be performed in the liquid phase to maintain the correct blend ratio.
3. 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.

   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.
