What F4 E3 means on a Maytag wall oven and how to reset and monitor it.
What this code means
F4 E3
F4 E3 may indicate a problem with the Microwave Exhaust Air Temperature Sensor or associated wiring.
If F4 E3 appears on your Maytag wall oven, the manufacturer’s help page says the cause may be the Microwave Exhaust Air Temperature Sensor or associated wiring. The help page covers Maytag wall ovens and does not limit the code to one model series.
Reset the power and watch the oven
Interrupt the oven’s power for one (1) minute using its circuit breaker(s). Switch the breaker(s) on to bring the oven back up. Keep an eye on the display for one (1) minute; the code should not reappear. The last step is to verify oven operation.
Persistent F4 E3 messages are a reason to ask for service; the help page points that way too.
Neighbouring codes worth a look: F4 E2 (the microwave sensor/thermistor and microwave appliance manager); F4 E4, covering the microwave humidity sensor and appliance manager.
