Whirlpool Oven Error Code 51

Error code 51 means the oven control board has detected a BAKE or BROIL over-temperature condition. This can result from a faulty temperature sensor sending an incorrect high-temperature reading, damaged wiring in the sensor circuit, or in some cases an actual overheating event caused by a stuck relay. The oven disables its heating functions when this code appears as a safety measure.

No, you should not use the oven while error code 51 is active. The code indicates either a sensor fault or a genuine over-temperature condition, both of which require diagnosis before continued operation. Running the oven with a stuck relay or undetected wiring fault could present a fire risk or cause further damage to the control board.

Repair costs depend on the faulty component. A replacement oven temperature sensor typically ranges from $20 to $60 for the part, making it one of the more affordable fixes. A new electronic control board generally costs between $150 and $350 for the part alone. Adding professional labor charges can bring the total repair cost to anywhere from $100 to $500 or more depending on your location and the specific model.

A knowledgeable DIYer can handle the initial diagnostics by unplugging the range, disconnecting the temperature sensor from its harness, and measuring resistance across the sensor pins with a multimeter. If the sensor reads outside the expected range of roughly 1080 to 1100 ohms at room temperature, replacing the sensor is a straightforward repair. Control board replacement is also a DIY-capable job but requires careful handling of electrical components.

Unplugging the oven for a few minutes may temporarily clear the display, but error code 51 will return if the underlying fault has not been corrected. A reset does not repair a faulty sensor, damaged harness, or defective control board. Clearing the code without fixing the root cause means the oven may shut down again during the next cooking cycle.
