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

1. Unplug the Refrigerator: Before conducting any repairs or checks.
2. Consult the User Manual: Refer to the specific user manual for your model for additional troubleshooting guidance.
3. 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.
