Whirlpool Oven Error Code 52

Error code 52 on a Whirlpool oven means the control board detected an over temperature condition during the self-clean cycle. The oven shuts down the cleaning operation as a safety measure when temperatures exceed the acceptable upper limit. This fault is most commonly traced to a failing oven temperature sensor or a wiring issue in the sensor circuit.

You should not attempt to run another self-clean cycle while code 52 is active, as the underlying fault may allow the oven to reach unsafe temperatures. Normal cooking at standard temperatures may be possible if the oven is otherwise functioning, but the temperature sensor fault should be resolved before relying on the oven for accurate temperature control. Have the sensor and wiring inspected before continued use.

If the oven temperature sensor is the cause, parts typically range from $20 to $60 depending on the model, and the repair is relatively simple. If a service technician is needed for diagnosis and replacement, total repair costs including labor generally range from $100 to $250. Control board replacement, if required, is more expensive, with parts and labor costs typically ranging from $200 to $400 or more.

A knowledgeable DIYer can perform the initial diagnostic step by unplugging the range, disconnecting the temperature sensor from its harness connector, and measuring sensor resistance with a multimeter. If the resistance reading is clearly outside the expected range at room temperature, replacing the sensor is a straightforward repair. However, if the sensor tests good, the issue may involve the control board or wiring, which can be more complex to diagnose and repair safely.

Unplugging the oven or cycling the circuit breaker may temporarily clear the code, but it will return if the underlying problem is not repaired. The code is triggered by an actual fault condition in the temperature sensor circuit, so a reset alone is not a fix. Address the root cause, such as a failed sensor or loose wiring, before attempting the self-clean cycle again.
