What F3 E4 means

F3 E4 on a Whirlpool built-in microwave or microwave drawer such as WMC50522AS is a meat probe code. The brand's advice is to verify that the probe is securely inserted in its receptacle, and the receptacle's location may vary by model. If the probe is seated and the code stays, the power reset applies. You will see F3 E4 on the display. The seating check is the simplest thing to rule out first.

Common causes of F3 E4

  • Probe not fully inserted in the receptacle
  • Meat probe itself
  • Receptacle contacts or wiring
✓ One safe check you can try

1. Pull the meat probe out of the receptacle and push it back in, firmly and fully. 2. Switch the microwave's breaker off for a minute. 3. Switch it back on. 4. See whether F3 E4 appears again within a minute. 5. If it does, call us, because the probe, receptacle or wiring needs a test.

! Why to stop there
  • A well-seated probe that still triggers F3 E4 points to the probe, the receptacle or the wiring, which we test one by one.
  • We check the receptacle contacts and read the circuit before replacing anything.
  • You see a written price before we start.
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.

F3 E4F3 E4 questions
What is the first thing to check for F3 E4?

Check that the meat probe is pushed all the way into its receptacle. The brand says to verify it is securely inserted, and the receptacle location may vary from one model to another.

The probe is firmly in and F3 E4 is still there. Now what?

Do the breaker reset: off for one minute, then on. If the code returns, the probe, receptacle or wiring needs testing, and we can do that on site.

Is it okay to cook without the probe?

If the display clears, you can usually cook without the probe. If F3 E4 appears again when no probe is in use, stop using the oven and book a check.
