Whirlpool Microwave Error Code F2-E2

F2-E2 means the control board detected an oven cavity temperature above 575 degrees Fahrenheit (302 degrees Celsius) while the microwave was in COOK mode. The unit shuts down automatically as a safety measure. The cause can be either a genuinely overheated cavity or a faulty thermal sensor reporting an incorrect temperature. The unit should not be used until the fault is diagnosed and resolved.

No. The F2-E2 code indicates a potential overheat condition, and continuing to use the microwave before resolving the fault could result in damage to internal components or a fire hazard. A welded relay, in particular, can cause the magnetron to run uncontrolled. Keep the microwave unplugged until the fault is properly diagnosed.

Repair costs vary depending on which component has failed. A replacement thermal sensor is typically the least expensive fix, with parts generally ranging from $15 to $50. A control board replacement is more costly, usually falling in the range of $80 to $200 or more for the part alone. Adding professional labor will increase the total cost, and for older or lower-priced units, replacement may be more economical than repair.

Unplugging the microwave may clear the displayed code temporarily, but if the underlying cause is still present, the fault will return during the next cook cycle. A welded relay or shorted sensor will continue to trigger F2-E2 regardless of resets. Resetting without diagnosing the root cause is not a reliable fix and can be a safety risk.

Start by disconnecting power, then check the thermal sensor connection and measure the sensor's resistance to confirm it is reading correctly. Inspect the control board for any relays that appear burned or welded closed. Also verify the cooling fan operates properly. Depending on the findings, the repair will involve replacing the thermal sensor, the control board, or the cooling fan.
