Kenmore Cooktop Error Code E03

The E03 error code on a Kenmore cooktop is a split display fault, meaning it appears simultaneously on the individual cooking zone screens as the letter E and on the main controller screen as the number 03. This dual-display behavior indicates the fault has been detected and logged at the controller level, which coordinates communication between the cooking zones and the central control board. The code signals a detected system fault that requires service attention rather than routine user correction.

The E03 code typically points to a communication or hardware fault within the cooktop's control architecture. Kenmore induction and electric cooktops route operational signals between zone modules and a central controller, and a breakdown in this pathway, whether from a failed component, a loose internal connection, or a control board fault, can trigger this error. The code does not self-resolve under normal cooking conditions and will persist or immediately return after power cycling if an underlying hardware issue is present.

The first recommended diagnostic step is a full power reset by unplugging the unit, waiting a short period, and reconnecting power. This clears any transient electrical faults or controller lockups that may have triggered the code without a true hardware failure. If the E03 code returns immediately upon reconnecting power, the cooktop should remain unplugged and a qualified technician should be called. Continuing to operate the appliance after a persistent E03 is not recommended, as the root fault has not been identified.
