What F6 E3 means

F6 E3 is shown by Whirlpool built-in microwaves and microwave drawers, for instance model WMC50522AS, when the control side of the appliance reports a problem. The wording behind it names the appliance manager control, the converter control and the wiring that joins them. Unlike its F6 E1 and E2 siblings, this one is not about a temperature sensor. You will see F6 E3 on the display and the cooking functions will not start as usual.

Common causes of F6 E3

  • Appliance manager control
  • Converter control
  • Wiring and connectors between the control boards
✓ One safe check you can try

1. Go to the electrical panel and shut off the breaker for the microwave. 2. Leave it off for one minute by the clock. 3. Restore power and watch the display for another minute. 4. If F6 E3 stays gone, start an ordinary cycle and make sure heating and the display behave.

! Why to stop there
  • The reset only clears a stuck reading, so a code that comes back means one of the control boards or their wiring needs testing.
  • We check the converter and manager circuits one at a time and name the responsible part before you approve anything.
  • Control boards are costly, so we confirm the cause first and give a written price before ordering.
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.

F6 E3F6 E3 questions
Why does F6 E3 not mention a sensor?

This code belongs to the control boards rather than a temperature circuit. It points to the appliance manager control, the converter control, or the wiring that links them.

Is it safe to reset the breaker?

Yes, switching the dedicated breaker off for a minute and back on is a normal reset. Do not open the unit or touch wiring; leave anything inside the cabinet to us.

What happens if F6 E3 keeps returning?

A repeat means the cause is still present. We test the control circuits, tell you which part is responsible, and quote the repair in writing before work starts.
