None Refrigerator: compressor issues
What is this symptom?
Experiencing issues with your refrigerator's compressor? Symptoms include the compressor not running, clicking sounds, overheating, or failing to start, leading to inadequate cooling and unusual noises. These problems often arise from a faulty start relay, dirty condenser coils, or other mechanical failures, requiring immediate attention to prevent food spoilage.
Possible Causes
Faulty compressor start relay or overload protector
How to Identify: Clicking sounds near compressor, compressor not starting despite power being present.
Part: Start relay / overload protector
Dirty or obstructed condenser coils
How to Identify: Compressor overheats, frequent shutdowns, poor cooling, and dusty coils at back or bottom.
Part: Condenser coils
Faulty thermostat or control board
How to Identify: Compressor never engages despite correct power; no response to temperature adjustments.
Part: Thermostat / control board
Condenser fan motor failure
How to Identify: No airflow over coils leading to overheating and compressor shutdown.
Part: Condenser fan motor
Overheating due to poor ventilation or overwork
How to Identify: Back of fridge hot to touch, high energy use, cycling frequently.
Part: Compressor housing
Internal compressor failure
How to Identify: No start or continuous loud humming with no cooling after relay tests.
Part: Compressor motor

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.
Thermostat
Regulates temperature by turning the heating or cooling system on or off.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.
Condenser Fan Motor
Moves air across the condenser and compressor compartment to remove heat.
Model-compatible Refrigerator parts
Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.

Maintenance supplies
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
-
Unplug the refrigerator and locate the compressor. Check the overload relay for signs of damage. If damaged, replace it with a new one. Ensure all connections are secure before plugging the refrigerator back in.
-
Turn off the refrigerator and clean the condenser coils using a vacuum or a coil cleaning brush. Make sure to remove any dust or debris that could be obstructing airflow. Turn the refrigerator back on and monitor the compressor's performance.
-
Disconnect the refrigerator from power. Locate the start capacitor on the compressor. Test it with a multimeter; if it shows no continuity, replace it with a new capacitor. Reconnect power and check if the compressor starts.
