Maytag Oven Error Code F3 E1 — Upper Oven Temperature Sensor Failure
What this means
The F3 E1 error code indicates the upper oven temperature sensor (in double oven models) or the main oven sensor has failed. The sensor is not providing valid temperature data to the control board, which causes incorrect heating — food may come out undercooked or burnt. The sensor may be degraded from age and heat cycling.
Alternate codes: F3E1
Step-by-step fix
4 stepsReset the oven
Turn off the circuit breaker for 5 minutes, then restore power. If the sensor had a temporary reading error, the reset may clear it.
If the error only appears intermittently, the sensor may be degrading and should be replaced preventively.
Test the sensor resistance
Disconnect the sensor and measure its resistance with a multimeter. At room temperature, it should read 1,080-1,100 ohms.
Also test resistance while gently flexing the sensor wire — an intermittent break will cause the reading to jump.
Replace the temperature sensor
Remove the mounting screw(s) inside the oven cavity, disconnect the old sensor, and install the replacement. Route the wire the same way as the original.
Do not bend the new sensor excessively — it is a fragile probe.
Calibrate the oven
After replacing the sensor, use an oven thermometer to verify the oven reaches the set temperature. Adjust the temperature offset in the settings if needed.
Most ovens allow a +/- 35°F offset adjustment through the control panel.
When to call a professional
If the sensor tests good and the error persists, the control board temperature sensing circuit may be faulty.
