Whirlpool Range Error Code E2

E2 on a Whirlpool range means the oven control board detected an open circuit in the oven temperature sensor, with resistance reading above 3000 ohms. Because the board cannot get a valid temperature reading from the sensor, it disables bake and broil functions. The fault points to the sensor probe itself, the wiring harness connecting it to the board, or the connector pins at either end of that circuit.

The oven's bake and broil functions will not operate while E2 is active, so the oven cavity is unusable until the fault is resolved. Surface burners on a gas or electric cooktop are generally unaffected by this code and can still be used. Do not attempt to bypass the error to force the oven to run, as operating without a functioning temperature sensor means the oven has no way to regulate or limit cavity temperature.

Disconnect power to the range, then locate the oven temperature sensor probe on the back wall of the oven cavity. Unplug the sensor's wire harness connector and set an ohmmeter to measure resistance. Place the probes on the two sensor terminals and record the reading. Compare the value to the resistance chart in your model's service manual or tech sheet, which is typically found behind the lower kick panel. A reading above 3000 ohms or an open-circuit reading confirms the sensor is faulty. If the sensor reads correctly, test the harness for continuity between the sensor connector and the control board connector.

Start by testing the oven temperature sensor resistance using an ohmmeter at the sensor's connector pins and comparing the reading to the resistance chart in your service manual. At room temperature (approximately 70 degrees F), a good sensor typically reads around 1080 ohms. A reading above 3000 ohms or an open circuit reading confirms the sensor has failed and needs replacement. If the sensor reads correctly, inspect the wiring harness and connector pins for damage or corrosion before suspecting the control board.

If the oven temperature sensor probe is the cause, the part typically costs between $20 and $60 depending on the model, and replacing it is a manageable DIY repair requiring only a screwdriver. If a technician performs the repair, expect a service call fee plus labor, bringing the total to roughly $100 to $200. A control board replacement, if needed, costs significantly more in parts, often $150 to $350 for the board alone, making professional diagnosis worthwhile before purchasing that component.
