Maytag Oven Error Code F-4

F-4 indicates a shorted oven sensor or oven sensor wiring circuit. On Type B clock models, it is specifically defined as an oven sensor circuit fault. The control board detected an electrical short in the temperature sensor loop, which prevents accurate temperature monitoring. This typically disables oven operation until the fault is corrected.

It is not recommended. The F-4 code means the oven cannot accurately monitor its internal temperature due to a sensor circuit fault. Operating the oven in this condition could result in uncontrolled temperatures, potential overheating, or inconsistent cooking results. The fault should be diagnosed and repaired before resuming normal use.

Repair costs vary depending on the failed component. A replacement oven temperature sensor typically costs between 20 and 60 dollars for the part, with additional labor costs if a technician performs the repair. A wiring harness repair or replacement can range from 30 to 150 dollars in parts depending on the extent of damage. Control board replacement, if required, is generally the most expensive option, often ranging from 100 to 300 dollars or more for the part alone.

Pressing the CANCEL button is the recommended first step and may temporarily clear the code. However, if the underlying short in the sensor or wiring is still present, the F-4 code will return when the oven is used again. A reset alone does not fix the electrical fault causing the code.

Start by pressing CANCEL and observing whether the code returns. If it does, disconnect power to the oven and use a multimeter to check the resistance and continuity of the oven temperature sensor and its wiring harness. A shorted sensor will need to be replaced. If wiring damage is found, the harness or affected section must be repaired or replaced. If the sensor and wiring both check out, the control board may need evaluation.
