What F1 E4 means

An F1 E4 on a Maytag built-in wall oven with a microwave points to the microwave appliance manager, the microwave power relay, or the wiring that links them. The relay switches the microwave power on, and the manager commands it. If either is off, the oven shows F1 E4 and the microwave function may not heat. Both parts sit on the microwave side, which is separate from the regular oven.

Common causes of F1 E4

  • The microwave appliance manager
  • The microwave power relay
  • Wiring and connections between the two
✓ One safe check you can try

1. Switch off the circuit breaker for the wall oven for one minute. 2. Switch it back on. 3. Watch the oven for a minute to see whether F1 E4 returns. 4. Verify that the oven and its microwave function work.

! Why to stop there
  • The code lists two parts, so a reset cannot separate them
  • We test the relay and the manager output step by step
  • Price in writing first, and a 30-day warranty on our repair
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.

F1 E4F1 E4 questions
What does the microwave power relay do?

It acts as a switch for the microwave power. The appliance manager tells it when to close. If either side misbehaves, the control reports F1 E4.

Is F1 E4 dangerous?

The oven is built to stop the microwave when it senses a problem. Do not keep trying to start it if the code returns. Let us test it.

Can an older Maytag combination oven be repaired for F1 E4?

Often yes. We quote in writing and tell you plainly if the cost does not suit the age of the oven.
