Error codeC
ApplianceRefrigerator
Seeing a C on a Kenmore refrigerator whose model number begins with 106 means a thermistor, the temperature sensor for one compartment, is no longer working. The display that carries the letter decides which sensor it is.
Reading the display
C on the refrigerator display: replace-or-repair work applies to the refrigerator compartment thermistor.
C on the freezer display: the freezer compartment thermistor and its harness are the focus.
Steps in order
Unplug the unit.
Look at the refrigerator thermistor wire harness. If it sits loose, push it back in place; if it is damaged, swap in a new harness.
A harness that checks out means the refrigerator compartment thermistor itself gets replaced.
For a C on the freezer display, repeat the same sequence on the freezer side: reseat or replace the freezer thermistor harness first, then replace the freezer compartment thermistor if the harness turns out fine.

Kenmore refrigerator service in San Francisco
Bay Area households with a Kenmore refrigerator showing C can read about Kenmore refrigerator repair and then call (415) 825-6393. Say which display carried the C and give the model number, so the right sensor is in mind before anyone arrives.
Model compatibility: Kenmore reuses codes across series and model years, so C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A compartment thermistor has failed, and the C appears on the refrigerator or freezer display.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
