Next step
Choose the next step for not working
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
Power Cord
Supplies mains power to the appliance and includes the model-specific plug and terminal connection.
- Typical part-only price
- $15 - $70
- DIY difficulty
- Medium
- Estimated time
- 20-45 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.
Main Control Board
The central brain of the appliance that controls all components, cycles, and timings.
Compressor
Compresses refrigerant within the sealed cooling system and requires specialized service equipment.
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.

User Suggested Solutions
-
Check and reset the circuit breaker or replace the blown fuse. Ensure the refrigerator is plugged in and the outlet is functioning. If the breaker trips again, there may be a deeper electrical issue.
-
Inspect and replace the main PCB if it shows signs of damage (burn marks, smell of burnt electronics). Ensure to disconnect power before working on the unit.
-
If the compressor is suspected to be damaged, consult a professional technician for diagnosis and replacement, as this involves handling refrigerants and high-voltage components.
