What F3 E0 means

F3 E0 on a Whirlpool built-in microwave or microwave drawer, for example WMC50522AS, relates to the upper oven temperature sensor. The brand also lists the control and the wiring as possible areas. The display shows the code and the oven does not carry on as usual. Because the guidance is a power reset with no named failed part, F3 E0 tells us which sensor circuit to test, not what to replace.

Common causes of F3 E0

  • Upper oven temperature sensor
  • Wiring and connector for that sensor
  • Control reading the sensor
✓ One safe check you can try

1. Turn the oven's breaker off. 2. Wait a minute, then turn it back on. 3. Look for F3 E0 on the display for a minute. 4. If the display is clear, run a short normal cycle to verify that the oven heats. 5. If F3 E0 reappears, stop using the oven and let us test the upper sensor circuit.

! Why to stop there
  • Resetting the power does not reveal whether the sensor, the wiring or the control is reading wrongly.
  • We check the sensor circuit first, then the control input.
  • The price is written and agreed before work, and repairs carry a 30-day workmanship warranty.
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 E0F3 E0 questions
What is the upper oven temperature sensor?

It is the sensor that tells the control how hot the upper oven cavity is. F3 E0 says the control has a problem with that reading, so it is a circuit check, not an automatic part replacement.

How is F3 E0 different from F3 E1?

F3 E0 refers to the upper oven sensor and F3 E1 to the lower one. Both share the same one-minute breaker reset, and we check the correct sensor circuit on the oven.

Is it safe to use the oven if F3 E0 clears?

If the code clears after the reset and the oven works normally, you can use it. If it returns, stop and have it checked, since the control is reporting a temperature problem.
