Kenmore Refrigerator Error Code Freezer Sensor

The Freezer Sensor error means the main control board has detected an abnormal electrical signal from the freezer temperature sensor, specifically indicating either a cut wire creating an open circuit or a short circuit in the sensor wiring. The board uses this sensor to monitor freezer temperature and regulate cooling. The error triggers when the sensor's resistance reading falls outside the range the board expects. The first place to check is the CON6 connector on the main PCB.

Continued use carries some risk because the control board may not regulate freezer temperature accurately without a working sensor. Food in the freezer could thaw or the compressor could run improperly. It is best to address the fault promptly, and in the meantime monitor freezer temperatures with a separate thermometer to make sure food stays safely frozen.

A power reset may temporarily clear the fault code from the display, but the error will return if the underlying wiring or sensor problem has not been corrected. Resetting by unplugging the refrigerator for a few minutes can be useful for confirming whether a glitch caused a false trigger, but a persistent error after reset indicates a real electrical fault that requires diagnosis and repair.

Many cases of this error can be resolved without professional help. Start by inspecting the CON6 connector on the main PCB for looseness or corrosion and reseat it firmly. If the connector is secure, trace the wiring harness from the freezer thermistor to the board and look for visible damage. A multimeter can help you test wire continuity and thermistor resistance to pinpoint the fault before purchasing any parts.

If only the connector needs reseating or cleaning, there is no parts cost involved. A replacement freezer thermistor typically costs in the range of $15 to $50 for the part. If the wiring harness needs repair or replacement, parts and labor can range from $75 to $200 depending on the extent of the damage. A main PCB replacement, if required, is the most expensive outcome and can range from $150 to $400 or more.
