Kenmore Refrigerator Error Code 6

Error code 6 on a Kenmore refrigerator means the control board has detected a failure in the room temperature sensor. This sensor measures the ambient temperature around the refrigerator and helps the unit adjust its operation accordingly. In display check mode, this error is confirmed by the Section A LED turning off. The first diagnostic step is checking the CON5 connector for a loose or faulty connection.

Error code 6 is not an immediately dangerous condition, but it does mean the refrigerator is operating without accurate ambient temperature data. This can affect cooling efficiency and compressor behavior over time. It is best to diagnose and resolve the issue promptly to ensure the refrigerator maintains proper food-safe temperatures.

If the fix is simply reseating the CON5 connector, there is no parts cost involved and a technician visit would typically fall in the range of $75 to $150 for a diagnostic call. Replacing the room temperature thermistor is generally an inexpensive repair, with parts typically ranging from $15 to $50 depending on the model. If the control board is at fault, replacement costs can range from $100 to $300 or more for parts alone.

Start by unplugging the refrigerator and inspecting the CON5 connector for loose, corroded, or bent pins, then reseat it firmly. If the connection is secure, use a multimeter to test the room temperature thermistor for a proper resistance reading at the current ambient temperature. A thermistor reading open or shorted will need to be replaced. If the sensor and wiring are both good, the control board may need further diagnosis.

A power reset may temporarily clear the displayed error, but if the underlying cause such as a loose connector or failed thermistor is not addressed, the code will return. Resetting should only be used after completing the recommended diagnostic steps and confirming the issue has been resolved. Clearing the code without a repair does not restore the sensor circuit to normal operation.
