KitchenAid Range Error Code F02

F02 means the electronic control board has detected a welded or stuck-closed relay in one of the oven element circuits, either bake, broil, or convection. A relay in this state cannot open to cut power to the element, meaning the element may stay energized even when the oven is off. This is a safety-relevant fault and the range should remain unplugged until the issue is resolved.

No, the range should not be used while F02 is active. A welded relay means an oven element could remain powered without any command from the control, creating a risk of unintended heating or overheating. Keep the range unplugged until the faulty relay or control board has been replaced.

Repair costs depend on whether the failed component is the control board alone or if a shorted heating element also caused the relay damage. A replacement electronic control board typically runs in the range of $150 to $350 for the part, with labor adding $100 to $200 if a technician is hired. If a heating element also needs replacement, expect an additional $30 to $100 for that component.

A knowledgeable DIYer can perform the initial continuity test at the control board connector pins P4-1 or P4-2 against P5-1, P5-3, or P5-4 to confirm which circuit has the welded relay. If the control board is confirmed faulty, replacing it is a manageable repair involving disconnecting wire harnesses and mounting hardware. However, given the safety implications of a stuck element relay, many technicians recommend professional service for this particular fault.

Resetting power will not clear F02 if the relay contacts are physically welded together. Because the fault is a mechanical failure of the relay, the control board will detect the same stuck-closed condition as soon as it powers back up and performs its internal checks. The underlying hardware failure must be repaired before the code will clear.
