Samsung PC CH — Samsung Ice Maker PC CH — Ice Maker Sensor Error
What This Code Means
The ice room temperature sensor (the sensor inside the ice-maker compartment) is reading an abnormal value. This code appears on French-door Samsung models with in-door ice makers.
Common Causes
- Failed ice room temperature sensor
- Ice buildup around the sensor obscuring its reading
- Disconnected sensor wiring in the door (common after ice maker removal/reinstallation)
DIY Steps to Try First
- Perform a forced defrost: enter diagnostic mode (press Fridge + Energy Saver for 8 seconds simultaneously), then select the defrost option.
- After defrost, allow the freezer to cool back down and check if PC CH clears.
- If you recently had the ice maker serviced or removed, check that all connectors in the door were reseated.
