Kenmore Cooktop Error Code E03

E03 is a fault code that appears when the cooktop's controller detects an internal system error. The code displays on both the individual cooking zone screens as E and on the main controller screen as 03. It indicates the cooktop requires service and will not resolve on its own if a hardware fault is present. Unplugging the unit and restoring power is the first step to determine whether the fault is temporary.

You should not continue using the cooktop while E03 is active. The code indicates a detected fault within the control system, and the nature of the fault is not fully known until a technician inspects the unit. Operating the appliance in this state could worsen the underlying issue or create a safety concern. Keep the cooktop unplugged until the fault is diagnosed and resolved.

The only DIY step supported for E03 is the power reset: unplug the cooktop, wait briefly, and reconnect power. If that does not resolve the code, the repair requires disassembly and inspection of internal components including the control board and wiring harnesses. This work should be performed by a qualified appliance technician, as working inside the cooktop involves high-voltage components.

A power reset will clear E03 if the fault was caused by a temporary controller glitch or a brief power irregularity. Unplug the cooktop, wait at least one minute, and plug it back in. If the code does not return, the reset was successful. If E03 appears again immediately, a hardware fault is likely present and service is required.

Repair costs depend on the root cause of the fault. A simple wiring reconnection at a service visit may cost in the range of $75 to $150 for labor. Replacing a main control board or zone module typically adds parts costs that can bring the total to $150 to $400 or more, depending on the specific component and local labor rates. Getting a diagnostic estimate before authorizing parts replacement is advisable.
