What F4 E3 means

Maytag built-in wall ovens with a microwave can display F4 E3. It refers to the microwave exhaust air temperature sensor, which watches how hot the air leaving the microwave section is, and to the wiring that serves it. If the control cannot read that sensor, it reports F4 E3 and may hold back the microwave function to protect the oven. You see the code on the display. The microwave is the part most likely to be affected, while normal baking and broiling may continue.

Common causes of F4 E3

  • The exhaust air temperature sensor
  • Wiring and connector to that sensor
  • The control reading it
✓ One safe check you can try

1. Turn the oven's circuit breaker off for one minute. 2. Turn it back on. 3. Check the display after a minute to see whether F4 E3 returns. 4. If it stays clear, make sure the vents and the area around the oven are free of anything stacked against them, then run a short microwave test.

! Why to stop there
  • A cleared code does not prove the sensor reads correctly, so it can return after heavy use
  • We check the sensor circuit with a meter, not by guessing
  • You will get a written quote first and a 30-day workmanship warranty afterward
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F4 E3F4 E3 questions
What does the exhaust air sensor do?

It measures the temperature of the air leaving the microwave section so the control can see if that section is running hot. Without a good reading the control cannot judge safely, so it shows F4 E3.

Should I worry about overheating?

The code is a sensing problem, not proof of overheating. Still, if the microwave side feels unusually hot or smells, stop using it and call us.

Why did the code show up after a long cooking session?

Long cycles raise the temperature in the cabinet, and a weak sensor connection can drop out under heat. That is why we test the sensor circuit warm as well as cold.
