What F2 E3 means

When a Whirlpool built-in microwave or microwave drawer, such as WMC50522AS, shows F2 E3, the oven is flagging a problem in its control panel circuit. The brand points to the user interface or keypad, the control behind it, or the wiring joining them. What you notice is the code on the display where the normal readout should be. Nothing in the guidance for F2 E3 names a single failed part, so we treat it as a circuit that needs checking.

Common causes of F2 E3

  • Control board behind the panel
  • Keypad or user interface
  • Wire harness and plug connections between them
✓ One safe check you can try

1. Find the microwave's breaker. Shut it off. 2. Wait sixty seconds. 3. Restore the power and look at the display. 4. After another minute with no code, try a brief cycle. 5. Should F2 E3 return, leave the oven unused and schedule a visit with us.

! Why to stop there
  • If F2 E3 returns after the reset, the reset has told us the condition is still there, but not which part causes it.
  • We begin with the connection between the panel and the control, then test the control itself.
  • You get the finding and a written price before we touch 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.

F2 E3F2 E3 questions
Is F2 E3 different from F2 E2?

Both are in the same family and the brand gives the same reset for each. The extra digit can matter to a technician, but the guidance does not give a different meaning, so we confirm on the oven itself.

Is it safe to leave the microwave plugged in with F2 E3 showing?

Do not rely on it while the code is up. A power reset at the breaker is a reasonable first step. If the code comes back, stop using the oven until it has been checked.

How long will the reset take?

About two minutes in total: one minute with the breaker off and one minute watching the display after power is restored. If the code is gone and the oven runs, you are done.
