What F8E5 means

F8E5 shows on Maytag over-the-range microwave and hood combinations when the oven could not execute a function. The manufacturer connects it to the exhaust air temperature sensor or its wiring. That sensor reports how warm the air leaving the unit is, so the control has a way to see whether cooling is working. With no usable reading, expect F8E5 and a microwave that quits or will not start.

Common causes of F8E5

  • The exhaust air temperature sensor
  • Wire and plug connections on that sensor
  • Airflow through the exhaust path
  • Control response to the sensor reading
✓ One safe check you can try

1. Turn off the circuit breaker that serves the microwave and wait one minute. 2. Turn the breaker on. 3. Give the unit a minute and look for F8E5 on the display. 4. Check that the exhaust openings are not covered or packed with items, then run a short cycle with a cup of water.

! Why to stop there
  • The code names a sensor circuit, not a part that has been proven bad
  • We test the sensor and its wiring, and we look at the exhaust path, before quoting
  • You see the price in writing before any work, and the repair is under our 30-day warranty
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.

F8E5F8E5 questions
Where is the exhaust air sensor?

It sits in the path of the air the microwave pushes out, inside the cabinet of the unit. We reach it ourselves, so you do not need to open anything.

The microwave still heats after a reset. Should I worry about F8E5?

If the code does not come back, treat it as a passing event. If it returns even once or twice, the sensor circuit needs checking before the next long cook.

Do you repair older Maytag over-the-range microwaves with F8E5?

Yes. Most are past warranty and still in daily use. We write down the price first and say honestly if a repair is not worth the money.
