Whirlpool Microwave Error Code F2-E3

F2-E3 indicates that the oven cavity temperature exceeded 950°F (510°C) during the CLEAN mode cycle. The control board monitors a temperature sensor and shuts down operation when this threshold is crossed to prevent damage or a safety hazard. The fault points to either a failed temperature sensor sending a false reading or a welded relay on the control board allowing uncontrolled heat buildup.

You should not attempt to run the CLEAN cycle again until the fault is diagnosed and resolved. If the cause is a welded relay, the heating circuit may not be controllable, which presents a genuine fire risk. Avoid using the clean function and have the appliance inspected before resuming normal operation.

Repair costs vary depending on which component has failed. A replacement temperature sensor is typically an inexpensive part, with the sensor itself ranging from around $15 to $50 and labor adding to the total if a technician is involved. Control board replacement is significantly more expensive, often ranging from $100 to $300 or more for parts and labor combined, depending on the specific model.

Some of the diagnostic steps are DIY-friendly, such as disconnecting power, reseating the sensor connector, and measuring sensor resistance with a multimeter. However, replacing control board components or relays requires comfort working with electronics and an understanding of appliance electrical systems. If the relay on the control board is welded closed, that condition involves live high-voltage circuits and is best handled by a qualified technician.

Disconnecting power and restoring it may temporarily clear the display, but F2-E3 will return if the underlying cause is not corrected. A shorted sensor or a welded relay will continue to trigger the fault every time the clean cycle is activated. Clearing the code without repairing the root cause does not make the appliance safe to use in CLEAN mode.
