None Refrigerator: compressor running continuously, fridge not cooling properly
What is this symptom?
If your refrigerator's compressor is running continuously while the internal temperature remains too warm or uneven, it could indicate serious issues. Common causes include dirty condenser coils, a malfunctioning evaporator fan, or frost-clogged coils. Addressing these problems promptly is crucial to avoid food spoilage and further damage.
Possible Causes
Dirty/clogged condenser coils preventing adequate heat dissipation
How to Identify: Dust, pet hair, or debris visibly accumulated on coils at rear or underside; fridge surface feels very hot.
Part: Condenser coils
Malfunctioning evaporator fan (stuck or broken)
How to Identify: No cold airflow inside, fan not running when doors open (listen near freezer area; cooling uneven between freezer and fridge. (iFixit
Part: Evaporator fan motor/blades
Frost‑clogged evaporator coils/defrost system failure
How to Identify: Excess frost buildup on freezer coils, weak/blocked airflow inside, freezer overly frosted. (iFixit
Part: Evaporator coils/defrost heater or defrost control
Faulty condenser fan motor
How to Identify: Compressor runs but condenser fan not spinning; fridge surface overheats. (ECH商用电器维修
Part: Condenser fan
Refrigerant leak or compressor internal fault
How to Identify: Compressor runs constantly without cycling off and no cold produced; hissing noises or oil residue may be present.
Part: Compressor/refrigerant circuit
DIY Solutions
Clean condenser coils
- Unplug the refrigerator.
- Locate condenser coils (rear/underneath).
- Use vacuum/brush to remove dust and debris from coils.
- Plug refrigerator back in and monitor temperature over next 24–48 hours.
Check and clear airflow inside fridge/freezer
- Remove items blocking vents inside fridge/freezer to ensure air can circulate.
- Ensure freezer vents are not blocked by frost or food.
- Observe if cooling improves over next few hours.
Inspect evaporator fan operation
- Unplug refrigerator.
- Open freezer panel to access evaporator fan.
- Check if fan spins freely by hand and reconnect power briefly to test operation (only if safe).
- Replace fan motor if confirmed faulty.

Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.
Most relevant component to inspect
Condenser Coil Assembly
Releases heat from the refrigerant circuit and must match the appliance's sealed-system design.
- Typical part-only price
- $80 - $400
- DIY difficulty
- Hard
- Estimated time
- 120-240 mins
Where can I find the model number?
Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.
Verify the complete model and part number on the retailer's compatibility page before ordering.
Other parts options
Check related components first; use model search as a fallback.
Evaporator Fan Motor
Circulates cold air from the evaporator through the refrigerator or freezer compartments.
Defrost Heater
Melts frost buildup on the evaporator coils during the defrost cycle.
Condenser Fan Motor
Moves air across the condenser and compressor compartment to remove heat.

These products support cleaning or routine upkeep. They are separate from the possible repair components above and are not claimed to fix this error code or symptom.
Refrigerator Condenser Coil Brush
For routine cleaning of accessible condenser areas where the manufacturer permits it. It does not repair a sealed-system or compressor fault.
Model-Compatible Refrigerator Water Filter
A routine replacement item on models with a water filter. Match the complete appliance model and existing filter number before ordering.
Compatibility check required: use the complete appliance model and compare the existing filter, bag, or specification before ordering.

User Suggested Solutions
-
Clean the condenser coils: Unplug the refrigerator, locate the coils (usually at the back or beneath), and use a vacuum or brush to remove dust and debris. Plug the refrigerator back in and monitor the temperature.
-
Check and replace the thermostat: Locate the thermostat inside the fridge, test it with a multimeter for continuity, and replace it if faulty. Ensure the new thermostat is calibrated properly.
-
Identify and repair refrigerant leaks: Use a leak detection kit to find leaks, and if found, call a professional to repair and recharge the refrigerant.
