The PC error on some Kenmore ice maker models indicates a control board communication reset is needed. The unit has detected an inconsistency in its operating state and requires a full power cycle to recover.
What To Do
- Unplug the ice maker (or turn off the water and power supply).
- Wait 5 minutes to allow capacitors to fully discharge.
- Reconnect power and restart.
- If PC returns, the control board may require professional replacement.
