What F1 E3 means

F1 E3 on a Whirlpool built-in microwave or microwave drawer, such as model WMC50522AS, points to the microwave appliance manager, the board that coordinates the microwave functions, or to the wiring connected to it. The control has reported a problem there and shows the code on the display. You will usually find the oven will not start a cycle or stops one partway. The guidance gives a power reset only and names no confirmed failed part.

Common causes of F1 E3

  • Microwave appliance manager
  • Wiring and connectors to the appliance manager
✓ One safe check you can try

1. Turn off the circuit breaker for the microwave and leave it off for one minute. 2. Turn the breaker on again. 3. Watch the oven for one minute and make sure F1 E3 stays away. 4. If it does, verify operation with a short cycle. 5. If it returns, stop using the oven and call us.

! Why to stop there
  • We check the connectors to the appliance manager before concluding the board itself is the problem.
  • A code that returns right after a reset means the circuit still has an issue, which only testing can pin down.
  • You see a written price before we replace anything.
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 E3F1 E3 questions
What is the microwave appliance manager?

It is the board that handles the microwave's operation and talks to the main control. F1 E3 says that board or its wiring may have a problem.

How is F1 E3 different from F1 E4?

F1 E3 names the appliance manager only. F1 E4 names the appliance manager or the microwave power relay, so the second code widens the search to the relay.

Can I use the oven if the code clears?

If it stays clear and the oven runs normally, yes. Note when it returns and call us if it does, so we can test it before it stops working.
