F3Warning
Maytag Oven/Range F3 Error Code
The oven temperature sensor is shorted (resistance too low), causing erroneous temperature readings.
Common causes
- Faulty oven temperature sensor (RTD) - shorted
- Moisture or contamination on sensor connector
- Control board failure
How to fix it
- Turn off power at the breaker for 5 minutes and restore power to reset the control.
- Remove the oven temperature sensor from the oven cavity and inspect for damage or corrosion.
- Measure sensor resistance with a multimeter; it should be around 1100 ohms at room temp. If near 0 ohms, replace sensor.
- Check the sensor connector on the control board for signs of moisture or corrosion.
⚠ When to call a pro: If replacing the sensor does not clear the error, the control board is likely defective.
