F4 E3 explained
Quick answer for F4 E3: Maytag says there may be a problem with the Microwave Exhaust Air Temperature Sensor or associated wiring.
Scope: Maytag wall ovens, series not specified.
What to try
Turn off the circuit breaker or breakers feeding the oven and leave it off for one (1) minute. Turn the power on again at the circuit breaker(s). Watch the oven for one (1) minute to make sure the code does not come back. End with a check that the oven operates.
