Maytag Oven Error Code F-3

F-3 on a Maytag oven signals a fault in the oven temperature sensor circuit. On most models, it means the sensor or its wiring has an open circuit, so the control board cannot read oven temperature. On ovens with a Type B clock, the code instead indicates a shorted sensor circuit. In either case, the oven stops operating normally to prevent unsafe temperature conditions.

You should not attempt to use the oven while F-3 is active. The code means the control board cannot reliably monitor oven temperature, which removes the safety regulation that prevents overheating. Disconnect power and address the sensor or wiring issue before operating the appliance again.

After pressing CANCEL and disconnecting power to the oven, locate the temperature sensor probe mounted at the rear wall inside the oven cavity. Disconnect the sensor's wiring connector and use a multimeter set to measure resistance (ohms) across the two sensor terminals. An open circuit reading or a reading that falls far outside the expected resistance range for the sensor indicates the sensor has failed and needs replacement. Also inspect the wiring from the sensor back to the control board for any visible damage or loose connections.

Pressing the CANCEL button is the recommended first step and may temporarily clear the F-3 code. However, if the underlying sensor or wiring problem still exists, the code will reappear the next time the oven is used. A cleared code without a repair is only a temporary reset, not a fix.

If only the oven temperature sensor needs replacement, parts typically range from $20 to $60 depending on the model, making it one of the more affordable oven repairs. If a professional technician is needed for diagnosis and installation, total costs including labor generally fall between $100 and $250. Wiring repairs may fall on the lower end of that range, while control board replacement would push costs higher.
