Maytag Range Error Code F1:1

F1:1 on a Maytag range means the control board has detected an oven temperature above 650°F during bake mode, which it classifies as a thermal runaway condition. The range shuts down automatically to prevent overheating damage or a fire hazard. The fault can be caused by a defective temperature sensor, a wiring problem, or an actual overheating event. Diagnosis starts with inspecting the oven temperature sensor, its harness, and all related connections.

A power reset by unplugging the range or turning off the circuit breaker for a few minutes may temporarily clear the F1:1 code, but it will return if the underlying problem is not corrected. If the sensor, harness, or control board is defective, the runaway condition will be detected again as soon as the oven heats up. A reset is useful for confirming whether the fault is persistent, but it is not a repair.

Repair costs vary depending on the failed component. A replacement oven temperature sensor typically costs in the range of $20 to $60 for the part, making it the most affordable fix if that is the cause. A new electronic range control board can range from $100 to $300 or more for the part alone. Adding professional labor will increase the total cost, generally ranging from $150 to $400 or higher depending on the repair needed and your location.

No, you should not continue using the oven while F1:1 is active. The code indicates either that the oven is actually overheating beyond 650°F or that a component failure is causing the control board to lose reliable temperature monitoring. Either condition presents a fire or safety risk, and the oven should remain out of service until the fault is diagnosed and repaired.

Start by inspecting the oven temperature sensor and checking its resistance with a multimeter. Next, examine the wiring harness from the sensor to the control board for damage, shorts, or loose connections. If the sensor and wiring check out, inspect the bake element for signs of shorting. If all those components test correctly, the electronic range control board may need to be replaced.
