What F1E1 means

F1E1 appears on two Whirlpool microwave platforms with different meanings. On built-in microwaves and microwave drawers, such as model WMC50522AS, it points to the oven appliance manager control or its wiring. On over-the-range microwaves, such as models WMH31017HS, WMH32519HZ and WMH53521HZ, it means the oven could not execute the function, and the relay control board or its wiring may be involved. In both cases the oven may stop or refuse to start.

Common causes of F1E1

  • Built-in: oven appliance manager control
  • Over-the-range: relay control board
  • Wiring and connectors on either platform
✓ One safe check you can try

1. Shut off the breaker that powers the microwave and let it rest for a minute. 2. Turn it on again. 3. Watch the microwave for one minute to make sure F1E1 does not return. 4. Verify operation with a short cycle. 5. If it comes back, stop and call us.

! Why to stop there
  • We first confirm which platform you have, because the board we test is different.
  • A relay or manager board cannot be judged from the display, so we test the circuit under load.
  • The price is in writing before work starts.
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.

F1E1F1E1 questions
Why does F1E1 mean different things?

The same characters are used on built-in and over-the-range microwaves. On the first it names the appliance manager control, on the second the relay control board.

How do I know which microwave I have?

A built-in sits in cabinetry or a drawer. An over-the-range mounts above the cooktop. Give us your model number and we confirm it. Give us your model number and we confirm which one it is.

Does a reset help with F1E1?

It can clear a brief glitch. If F1E1 returns, the board or wiring needs testing, and we give a written price after the diagnosis. Nothing is replaced without testing.
