Maytag Range Error Code FF

The FF code means the control board detected oven temperature above 585°F at the same time it found a fault in the door latch switch or door circuitry, and this condition persisted for at least 16 seconds. The code covers two simultaneous problems: excessive heat and a door circuit failure. You need to address both the temperature runaway and the door latch system to clear the fault.

Start by switching off the circuit breaker and letting the oven cool completely, which can take an hour or more. Once cool, inspect the door latch switch and the wiring harness running from the latch to the control board, looking for burned insulation, loose connectors, or a physically damaged switch. If the latch switch tests faulty with a multimeter, replace it. If the wiring and switch check out, the control board relay or the oven temperature sensor may be responsible for the runaway heat condition.

Disconnecting power will reset the display, but the FF code will return if the underlying fault with the door latch switch, door circuitry, or temperature control is not repaired first. A power reset is a necessary first step to let the oven cool safely, not a fix. If the code comes back when power is restored, continue diagnosing the door latch assembly and the components that control oven temperature.

No, you should not use the range while FF is active. Temperatures above 585°F can damage the oven cavity, door gasket, and internal wiring. The door circuit fault also means the control board cannot confirm whether the door is properly secured, which is a safety concern during high-heat operation. Disconnect power at the breaker and leave it off until the issue is diagnosed and repaired.

A replacement door latch switch typically costs between $20 and $60 for the part alone, making it one of the more affordable repairs if the wiring harness is intact. A new oven temperature sensor runs roughly $20 to $50. A control board replacement is the most expensive possibility, often ranging from $150 to $350 or more for the part, plus labor if you use a technician. Diagnosing which component is actually at fault before ordering parts will save money, and a multimeter is all you need to test the latch switch and temperature sensor resistance.
