The F3 error code on a Maytag oven indicates that the oven temperature sensor is not working correctly. This error code can happen for a variety of reasons, but typically it is due to a faulty sensor or a problem with the wiring. If the error code is displayed, it is recommended that you call a qualified technician to help diagnose and repair the problem.
1. Check the wiring harness for the oven temperature sensor
To check the wiring harness for the oven temperature sensor on a Maytag oven, start by unplugging the oven from the wall. Open the door and check to see if the sensor is attached to the oven door. If it is not, remove the sensor and replace it with a new one. Once the sensor is attached, plug the oven back in and check to see if the error code changes. If the code does not change, the wiring harness is likely defective and needs to be replaced.
2. Check the oven temperature sensor for continuity
- Verify that the oven is plugged in and turned on.
- Open the oven door and check to see if the temperature probe is in contact with the oven interior.
- If the temperature probe is not in contact with the oven interior, remove the probe and re-insert it into the same location.
- If the temperature probe still does not detect continuity, the oven temperature sensor may be defective and must be replaced.
3. Check the wiring harness for the oven door lock switch
- Disconnect the power to the oven by unplugging the power cord from the wall outlet.
- Open the oven door and remove the insulation from the wiring harness connector.
- Test the continuity of the wires to the connector by touching each wire to each other. There should be a minimum of two wires connected to the connector.
- Reconnect the power to the oven and close the oven door.
- Check the error code by entering the code into the oven's display. If the error code is not listed, replace the wiring harness.
4. Check the oven door lock switch for continuity
- Check the switch for continuity by touching it with a small probe or test light.
- If the switch is not continuous, replace it.
- Close the oven door and test it again.
5. Replace the oven temperature sensor
- Turn off the oven by unplugging the power cord.
- Remove the oven racks by pulling out on the arms.
- Locate the oven temperature sensor by looking for a white wire with a black connector attached to it near the back of the oven.
- Remove the white wire from the black connector by gently twisting it until it comes off.
- Replace the oven temperature sensor by reattaching the white wire to the black connector and screwing it back in place.
- Reinstall the oven racks by pushing them back into place and plugging in the power cord.
