Whirlpool microwave F3E3: meat probe failure
F3E3 means the control is reading an invalid temperature from the meat probe circuit.

What the microwave is detecting
On models with a temperature probe, the control reads the probe's thermistor. A reading that is not close to a believable temperature sets F3E3.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A damaged meat probe (thermistor) or probe cable.
- Documented A fault in the main control (ACU) when a good probe does not clear the code.
Safe checks you can make
- Unplug the probe from its jack, check that the plug and cable are not crushed or burned, and seat it fully again.
- Cook without the probe until it is checked, using time or another program.
- Unplug the microwave (or switch off its breaker) for one minute, then restore power and see whether the code comes back.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- Reviews the probe temperature in the diagnostic menu against room temperature.
- Replaces the main control only if the code persists with a good probe.
- This requires professional testing. Every component behind the microwave's outer cabinet shares space with the high-voltage circuit, and the high-voltage capacitor can hold a lethal charge even after the unit is unplugged.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Microwave control board replacement | $230–$520 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Generally safe to keep using. Other functions can be used; avoid probe cooking until the probe is checked or replaced.

Repair or replace?
A fault code alone rarely justifies replacing a microwave. Most F3E3 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 8–10-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
