What F1-3 means on a Maytag range

F1-3 is triggered when the electronic control board detects that the upper oven cavity temperature has exceeded 950°F while the door latch is engaged in the locked position. This condition is most commonly associated with a self-clean cycle, during which the oven intentionally runs at high temperatures and locks the door for safety. The control board monitors the upper oven temperature sensor (RTD probe) continuously and throws F1-3 when readings climb beyond the 950°F threshold, indicating a runaway heating condition or a sensor sending incorrect data.

For homeowners, this code typically means your oven got hotter than it should have during a self-clean cycle, or the temperature sensor is sending a false high reading to the control board. The door lock mechanism keeps the door closed as a safety feature when temperatures are extreme. The oven may have shut off the heating elements automatically when the code appeared.

The most important first step is checking whether the oven actually reached a dangerous temperature or whether the sensor is misreporting. A faulty RTD sensor can send readings far above actual cavity temperature, triggering F1-3 without a true overheat event. Inspect the sensor resistance before replacing any other components.

Common causes of F1-3

  1. 01

    Faulty upper oven temperature sensor (RTD probe)

    Part replacement

    A failing RTD sensor can send erratic or inflated resistance readings to the control board, causing the board to interpret the oven temperature as exceeding 950°F even when the actual cavity temperature is normal. This is the most common cause of a false F1-3 code.

  2. 02

    Genuine oven temperature runaway during self-clean

    Part replacement

    If a relay on the control board sticks in the closed position, the bake or broil element can remain energized without limit, causing actual oven temperatures to exceed 950°F. This is a real overheat condition, not a sensor fault, and requires immediate attention.

  3. 03

    Damaged or shorted sensor wiring harness

    Part replacement

    Wiring between the upper oven temperature sensor and the control board can become damaged from prolonged heat exposure, causing a short that sends false high-temperature signals to the control board and triggering F1-3.

  4. 04

    Defective electronic control board

    Part replacement

    If the sensor and wiring both test within spec but F1-3 persists, the control board itself may be misreading the sensor signal due to a failed input circuit. This is the least likely cause and should only be diagnosed after ruling out the sensor and harness.

Frequently asked questions about F1-3

What does error code F1-3 mean on a Maytag range?
F1-3 means the control board detected that the upper oven temperature exceeded 950°F while the door was in the locked position. This most often occurs during or after a self-clean cycle. The code can indicate a genuine overheating event or a faulty upper oven temperature sensor reporting incorrect data to the board.
How do I fix F1-3 on a Maytag range?
Start by letting the oven cool completely and canceling the self-clean cycle if one is running. Once cool, check the resistance of the upper oven temperature sensor with a multimeter - at room temperature, a functioning RTD sensor typically reads around 1080 to 1100 ohms. If the resistance is out of range or erratic, replace the sensor. If the sensor tests correctly, inspect the wiring harness for damage, then evaluate the control board.
Is it safe to use my Maytag range with an F1-3 error code active?
No. Do not use the oven while F1-3 is active. The code indicates either a real condition where temperatures exceeded a safe threshold or a sensor fault that prevents the board from accurately monitoring oven temperature. In either case, the oven cannot regulate heat reliably until the underlying issue is repaired. The stovetop burners are generally unaffected, but the oven should remain off until the fault is resolved.
Can I reset F1-3 on a Maytag range by unplugging it?
Unplugging the range or cutting power at the breaker for several minutes may clear the code temporarily, but it will return if the root cause has not been fixed. If the code reappears immediately or during the next self-clean cycle, the upper oven temperature sensor, wiring harness, or control board needs to be inspected and likely replaced.
How much does it cost to repair a Maytag range with an F1-3 error code?
If the fault is the upper oven temperature sensor, the part typically costs $20 to $60 and replacement is manageable for a DIY homeowner since it usually involves removing two mounting screws and a wire connector inside the oven cavity. If the control board is the cause, parts range from $150 to $350 or more depending on the model, and professional installation adds labor cost. Getting a confirmed diagnosis before ordering parts will save money, since misidentifying the cause is the most common repair mistake with this code.
