Hotpoint Refrigerator Error Code F

The F code on a Hotpoint refrigerator indicates a failure in the refrigerator compartment thermistor, which is the sensor that monitors internal fridge temperature. The control board is not receiving a valid signal from the thermistor. The appliance continues to operate using default fixed settings, but it cannot actively regulate temperature the way it normally would. A technician should inspect and test the thermistor and its wiring circuit to resolve the fault.

The refrigerator continues to run on default operating parameters when the F code is active, so food may remain adequately cold in many conditions. However, without active temperature sensing, the appliance cannot respond to changes like a full load of warm groceries or a warm kitchen. It is advisable to monitor food temperatures closely and have the fault repaired promptly to avoid potential spoilage.

Performing a reset by unplugging the unit for a few minutes may temporarily clear the F code from the display, but the fault will return if the underlying thermistor issue has not been fixed. A reset does not repair a failed sensor, damaged wiring, or corroded connector. The code will reappear once the control board again detects an invalid signal from the thermistor circuit.

A knowledgeable DIYer can attempt to diagnose this code by locating the fridge thermistor, checking its wiring harness for visible damage, and testing the connector for corrosion or looseness. If the thermistor itself needs to be replaced, the part is generally accessible and the swap is straightforward. However, if the wiring or control board is involved, professional diagnosis is recommended to avoid misdiagnosis or additional damage.

Repair costs vary depending on the root cause. Replacing a thermistor sensor typically costs between $20 and $60 for the part, with labor adding to the total if a technician is hired. If the control board is the cause, parts alone can range from $80 to $200 or more. Getting a diagnosis first helps narrow down what needs to be replaced before committing to a repair cost.
