KitchenAid Refrigerator Error Code PC1
Compressor circuit fault
Common Causes
- 1Compressor relay failure
- 2Compressor winding failure
- 3Inverter board fault
Step-by-Step Troubleshooting
- 1
Listen at the rear — clicking every few minutes means the relay is trying to start a locked rotor
- 2
Check the compressor start relay/overload: remove from pins and shake — rattling means failure
- 3
Test compressor windings: run-to-start, run-to-common, start-to-common should all show resistance
- 4
On inverter models, check the inverter board for burn marks or swollen components
Pro Diagnostic Tip
The start relay is a $15-30 part that fails far more often than the $400+ compressor. Always test the relay first by shaking it. On KitchenAid built-in models, the inverter board is more common than on freestanding units — check it before condemning the compressor.
