Whirlpool Microwave Error Code F2-E0

F2-E0 means the microwave's control board has detected an open circuit in the temperature sensor. The temperature sensor is a thermistor that should read approximately 1080 ohms at 70 degrees Fahrenheit and 2875 ohms at the design reference point. When the board reads an out-of-range or infinite resistance value, it triggers this code and stops operation to prevent unsafe conditions.

No, you should not use the microwave while this fault is active. The temperature sensor is part of the overheat protection system, and operating without a functioning sensor removes an important safety safeguard. The microwave will typically prevent operation when this code is present, and that lockout should be respected until the fault is resolved.

Unplugging the microwave and restoring power may temporarily clear the display, but the code will return as soon as the control board reads the sensor circuit again if the underlying fault has not been fixed. A reset does not repair a failed sensor or damaged wiring. The fault must be diagnosed and corrected before the error will stay cleared.

Some cases are DIY-friendly, particularly if the fault is simply a loose wiring connector at the sensor. After unplugging the microwave, you can inspect and reseat the connector and measure the sensor resistance with a multimeter. If the sensor itself is open (reads OL or infinite resistance), replacing the thermistor is a straightforward repair for someone comfortable working inside a microwave. Always unplug the unit and allow capacitors to discharge before opening the cabinet.

If only the temperature sensor needs replacement, parts typically cost between $15 and $50 depending on the model, and the repair is relatively quick. If a professional technician is needed, total costs including labor generally range from $80 to $200. A damaged wiring harness or failed control board will push repair costs higher, and in those cases it may be worth comparing the repair cost against the price of a replacement unit.
