Whirlpool Microwave Error Code E2

E2 on a Whirlpool microwave means the temperature sensor circuit has opened and the control board is no longer receiving a valid resistance signal from the thermistor. The microwave shuts down to prevent unsafe operation without temperature feedback. The sensor should read approximately 1080 ohms at 70°F, and a reading of infinite resistance confirms the sensor or its circuit has failed.

No, you should not use the microwave while E2 is active. The temperature sensor is a safety component, and operating without it means the control board cannot detect overheating conditions. The microwave will typically prevent normal operation when this code is present, and attempting to bypass that lockout creates a fire and safety risk.

Unplugging the microwave for a minute and restoring power may temporarily clear the display, but the E2 code will return as soon as the control board checks the sensor circuit again and finds it open. A reset does not fix the underlying fault. The sensor circuit must be repaired or the failed component replaced before the error will stay cleared.

A knowledgeable DIYer can handle basic diagnosis such as checking the sensor connector and measuring thermistor resistance with a multimeter. If the sensor itself has failed, replacing it involves accessing the interior of the microwave cabinet. Keep in mind that microwave capacitors can retain a lethal charge even when unplugged, so anyone working inside the unit should know how to safely discharge the high-voltage capacitor before touching any components.

If the repair is only a loose connector, there may be no parts cost at all. A replacement temperature sensor typically costs in the range of $15 to $50 depending on the model. If professional service is needed, labor costs generally bring the total repair estimate to somewhere between $100 and $200, though costs vary by region and service provider.
