Maytag Oven Error Code F3E0

F3E0 means the main control board has detected an upper cavity temperature reading that is either above 995°F (535°C) or below 0°F (-18°C), which indicates an open or shorted condition in the upper oven temperature sensor circuit. This is not a normal operating temperature reading but rather a signal that something is wrong with the sensor, its wiring, or the connector at the control board. The oven will not function normally while this fault is active.

You should not continue using the oven while F3E0 is active. The control board relies on the upper cavity sensor to regulate temperature accurately and safely. Without a valid sensor reading, the oven cannot control heating elements properly, which creates a risk of overheating. Disconnect the oven from power until the fault is diagnosed and repaired.

Repair costs vary depending on which component has failed. A replacement upper cavity temperature sensor typically runs in the range of $20 to $60 for the part alone. A main control board is significantly more expensive, often in the $150 to $350 range for the part. Adding professional labor costs will increase the total, so a complete repair by a technician could range from around $100 to $500 or more depending on the failed component and local labor rates.

Some causes of F3E0 are DIY-friendly, particularly if the fault is caused by a loose connection at connector P10 on the main control board. Disconnecting power and reseating the connector requires no special tools. Replacing the upper cavity temperature sensor is also a relatively straightforward repair for experienced DIYers, as the sensor is typically secured with one or two screws and connects with a simple harness plug.

Unplugging the oven or disconnecting the circuit breaker for a few minutes may temporarily clear the F3E0 code, but it will return if the underlying problem is not fixed. If the sensor or wiring is genuinely faulty, the control board will detect the out-of-range signal as soon as power is restored and the code will reappear. A reset is only useful as a diagnostic step to confirm the fault is recurring, not as a fix.
