What F8 E3 means

If your Whirlpool built-in microwave or microwave drawer, for example WMC50522AS, displays F8 E3, the control is reporting a cooling problem in the same family as F8 E0, F8 E1 and F8 E2. The wording behind it mentions an airflow restriction, the oven cooling fan and the associated wiring. The unit stops its function and F8 E3 stays on screen. Our approach starts with what you can see and ends with what we can measure.

Common causes of F8 E3

  • Wiring or connector at the cooling fan
  • Oven cooling fan
  • Airflow restriction around the unit
✓ One safe check you can try

1. Switch the microwave's circuit breaker off. 2. Wait one minute before switching it on again. 3. Observe the display for sixty seconds. 4. While you wait, look over the vents and the cabinet space to make sure nothing is blocking them.

! Why to stop there
  • F8 E3 coming back after the reset means a hands-on test of the fan circuit, because the display cannot tell wiring from the fan itself.
  • We check the wiring end of the circuit first when airflow looks clear.
  • The written price and your approval come before any 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.

F8 E3F8 E3 questions
Does F8 E3 mean the fan is broken?

It means the cooling circuit is reporting a problem. That could be the fan, its wiring or restricted airflow. We test them in that order of ease and tell you which one it is.

What can I do besides the reset?

Make sure the vents and the space around the unit are clear. Do not open the unit or remove panels. If the space around the unit is cluttered, moving things away costs nothing and can save a visit.

Is there a warranty on the repair?

Yes. Finished repairs carry our 30-day workmanship warranty, and the price is quoted in writing before we start. The warranty covers the work we complete, and you decide after reading the number, not before.
