Seeing a ‘C’ or ‘C1’ error on your Whirlpool refrigerator display? Don’t panic! This code is typically pointing to an issue with the refrigerator compartment thermistor – essentially, the sensor that tells your fridge how cold it is. It’s a common problem, and often, it’s something you can troubleshoot yourself.
What Triggers This Error?
- The refrigerator compartment thermistor itself has failed, leading to inaccurate temperature readings.
- You might find loose or corroded connections within the wire harness that links to the thermistor.
- A break or short in the thermistor’s internal wiring could be the culprit.
- While less frequent, a faulty main control board unable to properly interpret the thermistor’s data could also trigger this alert.

Your Repair Action Plan
- Prioritize safety: always unplug your Whirlpool refrigerator from the wall outlet before attempting any diagnostic or repair work.
- Begin by locating the refrigerator compartment thermistor; its exact placement varies, but it’s often within the fresh food section, possibly near an air vent or light fixture. Access might require removing an internal panel.
- Carefully inspect the wiring connected to the thermistor, searching for any visible signs of damage, fraying, or corrosion along the harness.
- Disconnect and then firmly reseat the wire harness plugs, ensuring a solid electrical connection. A simple reconnection can sometimes resolve intermittent issues.
- If you possess a multimeter, consider testing the thermistor’s resistance – compare your readings against the service manual’s specifications for expected values at room temperature. An open or shorted thermistor confirms a fault.
- Should inspections and connection adjustments fail to clear the error, or if your multimeter confirms a defect, proceed to replace the refrigerator compartment thermistor with an appropriate, new part.
- After installing the new thermistor and verifying all connections are secure, reassemble any removed panels, plug the refrigerator back in, and then monitor it for the error code to disappear and proper cooling function to return.
