Emkarate RL 68H Compatibility Chart with HFC HCFC HFO
Understanding the chemistry between lubricants and refrigerants is vital for refrigeration longevity. While Emkarate RL 68H is a premium synthetic polyol ester (POE) oil designed for HFCs, its application with R600 (Isobutane) requires careful engineering…
| Refrigerant Class | Common Examples | Compatibility Status | Technical Reasoning (The “Why”) |
| HFC (Modern Generation) | R134a, R404A, R410A, R407C, R507 | Fully Compatible | These gases are polar and specifically require POE oils for proper miscibility, ensuring oil returns to the compressor. |
| HCFC (Legacy Transition) | R22, R123, R401A, R402A | Compatible | Ideal for “Retrofit” operations when converting older systems from Mineral Oil to more environmentally friendly HFC blends. |
| HFO (Eco-Friendly Gen) | R1234yf, R1234ze | Compatible | Exhibits high chemical stability, making it suitable for new low Global Warming Potential (GWP) refrigerants. |
| HC (Hydrocarbons) | R600a, R290 | Chemically Compatible | Miscibility is excellent, but viscosity is the barrier; small HC systems typically require lower viscosity (ISO 10-32). |
| Natural (Carbon Dioxide) | R744 | Compatible | RL 68H is robust enough to handle the high pressures and discharge temperatures typical of CO2 systems. |
| Ammonia | R717 | NOT Compatible | NEVER use with Ammonia. POE oils react chemically with R717, leading to sludge, corrosion, and system failure. |
| Lubricant Property | Emkarate RL 68H (POE) | Standard Mineral Oil (MO) |
| Base Fluid | Synthetic Ester | Petroleum Based |
| Moisture Sensitivity | High (Hygroscopic) | Low |
| Thermal Range | Excellent (High/Low) | Moderate |
| Application | HFC / Retrofit | CFC / HCFC / Ammonia |

LG washing machine error codes troubleshooting
Decoding LG washing machine error codes is essential for any technician or homeowner looking to maintain peak performance. From the common OE drainage error to the complex LE motor lock fault, understanding these digital signals…
| Error Code | Issue Description | Professional Diagnostic & Quick Fix |
| OE | Drainage Error | Inspect the drain hose for kinks. Clean the pump filter. Test the drain pump motor for continuity. |
| IE | Water Inlet Error | Verify water supply valves are open. Check inlet filters for sediment. Ensure house water pressure is adequate. |
| UE / uB | Unbalanced Load | Redistribute laundry evenly. Ensure the machine is perfectly level on the floor. |
| CL | Child Lock Activated | Not a fault. Press and hold the “Child Lock” button combination (often Prewash/Delay) for 3 seconds. |
| LE | Motor Lock Error | Possible heavy load. Reduce weight. Inspect the wiring harness between the PCB and the stator. |
| tCL | Tub Clean Reminder | Maintenance prompt. Execute the Tub Clean cycle using a high-quality citric-acid-based cleaner. |
| DE / DE1 / DE2 | Door Error / Lock Fault | Ensure the door is fully latched. Inspect the door switch and solenoid for electrical failure. |
| CE | Current / Drain Error | Can indicate a short circuit in the motor or a drainage obstruction. Inspect the main control board for scorch marks. |
| SUD | Excessive Suds Detection | High-efficiency (HE) detergent usage is mandatory. Run a rinse cycle to clear the drum. |
| FE | Overflow Error | Typically caused by a faulty water inlet valve that fails to close or a defective pressure sensor. |
| PE | Pressure Sensor Error | Check the air tube connecting the drum to the pressure switch. Verify the sensor’s frequency output. |
| PF | Power Failure | Indicates an interruption in electrical supply. Restart the cycle once power is stabilized. |
| TE | Heating Error | Inspect the heating element and the thermistor (NTC). Measure resistance values (typical 10k-15k ohms at room temp). |
| DHE | Motor Sensor Error | Focus on the Hall Effect sensor located on the back of the stator. |
| E6 | Motor Hall Sensor Fault | Often requires replacement of the Hall sensor or repairing the wiring harness. |
| Component | Expected Value (Approx.) | Fault Symptom |
| Inlet Valve Solenoid | 1.1k – 1.5k Ohms | IE Error, No water entry |
| Drain Pump Motor | 150 – 200 Ohms | OE Error, Standing water |
| Thermistor (NTC) | 10k – 15k Ohms (at 25°C) | TE Error, Water not heating |
| Stator Windings | 8 – 12 Ohms (between pins) | LE Error, Motor stuttering |
| Door Lock Solenoid | 50 – 150 Ohms | DE2 Error, Door won’t lock |
