Bosch Refrigerator Error Code F22

F22 on a Bosch refrigerator means the temperature sensor inside the cool-fresh compartment has been detected as short-circuited. The sensor's resistance has dropped to an abnormally low level, which prevents the control board from accurately reading the compartment temperature. The fault points to either the sensor itself or the wiring cable connecting it to the electronics module.

The F22 fault specifically affects the cool-fresh compartment's temperature monitoring, which means that zone may not be managed correctly while the error is active. Food stored in the cool-fresh compartment could be at risk of improper temperature control. The main refrigerator and freezer sections may continue operating, but it is best to address the fault promptly and avoid storing perishables in the affected compartment until the sensor is repaired.

Repair costs depend on what component has failed. A replacement cool-fresh compartment temperature sensor typically costs in the range of $20 to $60 for the part alone. If the wiring harness or electronics module also needs replacement, parts costs will be higher, and adding a technician's labor can bring the total repair estimate to anywhere from $100 to $300 or more depending on your location and the extent of the damage.

A knowledgeable DIYer can perform basic checks such as inspecting the sensor wiring harness for visible damage, drying out the connector if moisture is present, and checking connector terminals for corrosion. However, confirming a sensor failure requires measuring resistance with a multimeter, and replacing the sensor or wiring involves accessing internal refrigerator components. If you are not comfortable with these steps, a qualified appliance technician should handle the repair.

A power reset, such as unplugging the refrigerator for a few minutes and restarting it, will not permanently clear F22 if the underlying short-circuit condition in the sensor or its wiring is still present. The code will return once the control board performs its sensor diagnostics again. The fault must be corrected at the component level before the error will stay cleared.
