Marq Refrigerator Error Codes
| Error Code | Meaning | Solutions |
|---|---|---|
| E1 | Temperature sensor failure in the refrigerator compartment. |
– Check the temperature sensor for damage. Replace it if necessary. – Inspect the wiring for any loose or broken connections and repair them. – Check ohm on multimeter, value should be 1 (open) or short (0). |
| E2 | Freezer temperature sensor failure. |
– Inspect the freezer temperature sensor for damage. – Check ohm on multimeter, value should be 1 (open) or short (0). – Check wiring connections. – Replace the sensor if necessary. |
| E3 | Refrigerator compartment temperature sensor failure. |
– Test the refrigerator sensor for functionality. – Check ohm on multimeter, value should be 1 (open) or short (0). – Inspect and repair any faulty wiring. – Replace the sensor if it’s malfunctioning. |
| E4 | Communication error between the control board and display. |
– Check connections between the control board and display. – Check wiring continuity test. – Inspect the control board for faults. – If necessary, replace the control board. |
| E5 | Door open or door switch failure. |
– Ensure the refrigerator door is closed properly. – Check the door switch for continuity using a multimeter. – Replace the door switch if it’s faulty. |
| E6 | Over temperature condition. |
– Check for blockages in air vents. – Ensure the refrigerator is not overloaded. – Allow the appliance to cool down and check if the error persists. |
| E7 | Compressor or cooling system failure. |
– Inspect the compressor for damage or overheating. – Check electrical connections to the compressor. – Check condenser fan if available. – Check gas leakage. – Multimeter checks with ohm setting value should be same of three terminal of compressor (inverter). – C to G should be zero. – Normal compressor value CS+CR=SR and C to G should be zero. – If readings are ok then rotor may be locked, check for ampere, it should be under 1.5 amp. – If the compressor is faulty, it may need to be replaced. |
| E8 | Ice maker failure (if applicable). |
– Inspect the ice maker for blockages or jams. – Check the water supply line for kinks or clogs. – Check icemaker sensor below the tray. – Replace the ice maker if it is defective. |
| E9 | Temperature control failure. |
– Check the temperature control thermostat for faults. – Inspect the wiring and connections. – Replace the thermostat if it is malfunctioning. |
| F1 | Freezer or refrigerator compartment temperature too high. |
– Verify that the doors are sealed properly and are closing fully. – Ensure the vents are not blocked by food items. – Allow the refrigerator to cool and check the temperature settings. |
| F2 | Freezer or refrigerator compartment temperature too low. |
– Adjust the temperature settings to a warmer setting. – Check for any ice buildup in the evaporator. – Ensure the temperature sensors are functioning properly. |
| F3 | High humidity detected. |
– Ensure the refrigerator is in a dry location away from high humidity. – Check the door seals for any damage or wear. – Allow the appliance to stabilize and monitor humidity levels. |
| F4 | Compressor overheat. |
– Check for blockages in the condenser coils. – Ensure proper airflow around the refrigerator. – If the compressor is hot, allow it to cool down before restarting. |
| F5 | Fan motor failure. |
– Inspect the fan for obstructions. – Test the fan motor with a multimeter to check for continuity. – Replace the fan motor if it is not operational. |
| F6 | Defrost system failure. |
– Check the defrost heater and defrost timer for proper operation. – Inspect for any frost buildup that may be blocking airflow. – Replace components of the defrost system as needed. |
| F7 | Power failure or interruption. |
– Check for a blown fuse or tripped circuit breaker. – Ensure the refrigerator is plugged in and receiving power. – Reset the unit by unplugging it and then plugging it back in. |
General Troubleshooting Steps
- Unplug the Refrigerator: Before conducting any repairs or checks.
- Consult the User Manual: Refer to the specific user manual for your model for additional troubleshooting guidance.
- Reset the Refrigerator: Unplugging the unit for a few minutes can sometimes clear temporary error codes.
General Maintenance Tips
- Regular Cleaning: Keep condenser coils clean and free of dust to ensure efficient cooling.
- Check Door Seals: Regularly inspect door seals for wear to prevent cold air loss.
- Monitor Temperature Settings: Keep the temperature settings within the recommended range (usually around 3°C for the refrigerator and -19°C for the freezer).
- Organize Properly: Avoid overloading the fridge to ensure proper air circulation.
