To remove an error code from a Kenmore oven, disconnect the oven's power supply for 30 seconds, plug it back in, and then hire a professional to repair the control board if this doesn't work. The fault code on a Kenmore oven may vary depending on the manufacturer.
Kenmore product numbers start with a three-digit code, indicating which manufacturer made the product. Whirlpool is most common manufacturer of Kenmore products, including its ovens. Kenmore products with a model number starting with "110" are manufactured by Whirlpool.
While fault codes often indicate that a part of the oven needs to be repaired or replaced, some codes can be tripped by a minor electrical fluctuation. Disconnect the oven's power supply for at least 30 seconds, and plug it back in. If this doesn't fix the problem, the error code typically reappears within a minute.
Newer ovens, including many manufactured by Whirlpool, feature control boards that are prone to malfunction. Many of the error codes displayed by control boards are due to a fault in the control board itself. As a result, a number of error codes can only be removed by replacing the control board or hiring an expert to repair it.
