What F6 means

F6 depends on the style of Whirlpool microwave. On a built-in microwave or drawer unit like the WMC50522AS, it points to the oven control or its wiring. On over-the-range models in the WMH31017HS, WMH32519HZ and WMH53521HZ group, the oven was unable to carry out the function, and the brand points to the relay control board or its wiring. In both cases the display shows F6 and the guidance is a power reset, with no failed part named.

Common causes of F6

  • Oven control on a built-in microwave or drawer
  • Relay control board on an over-the-range microwave
  • Wiring and connectors serving that board
✓ One safe check you can try

1. Cut the microwave's breaker for sixty seconds. 2. Switch it on again. 3. Look for F6 on the display during the next minute. 4. When the display is clear, a short normal cycle shows whether it works. 5. If F6 comes back, stop using the microwave and call us.

! Why to stop there
  • A reset restarts the board but cannot show whether the board or its wiring is the cause.
  • We identify which style of microwave you have and test the matching control or relay circuit.
  • A written price comes before the 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.

F6F6 questions
Does F6 mean the same on a built-in and an over-the-range microwave?

The code points to a control board on both, but the board differs: the oven control on built-ins and drawers, and the relay control board on over-the-range models.

What does it mean when the oven was unable to run the function?

Over-the-range models can try a function and fail to complete it. The brand points to the relay control board and its wiring as the area to check.

Is a repair worth it on an older microwave?

It depends on the unit and the price. We say plainly when it is not worth repairing, and you see the written quote before any work.
