KitchenAid Cooktop Error Code C-82

C-82 is an over-temperature fault indicating the cooktop has exceeded its safe internal operating temperature due to insufficient ventilation. The cooktop's thermal protection system triggers this code to prevent damage to internal components and surrounding surfaces. It is not a random glitch but a signal that the unit is not getting the airflow it needs to operate safely.

No, you should not continue operating the cooktop while C-82 is active. The error indicates the unit has already reached or exceeded safe temperature limits, and continued use under those conditions risks damage to internal electronics, the cooktop surface, or nearby cabinetry. Allow the unit to cool completely and resolve the ventilation issue before resuming use.

If the fix is simply clearing blocked intakes or adjusting installation clearances, the cost can be minimal, often just the time needed to inspect and correct the setup. If the ductwork needs rerouting or a new duct run, materials and labor could range from roughly $100 to $300 or more depending on complexity. If a blower motor or thermal sensor requires replacement, parts and labor typically range from $150 to $450 depending on the specific component and local labor rates.

Start by reviewing the original installation instructions and checking all blower intake locations for blockages, debris, or grease buildup. Verify that all required clearances between the cooktop and surrounding cabinetry are met. If the installation checks out, inspect the ductwork for kinks or obstructions, and confirm the blower motor is functioning correctly. Clearing the airflow restriction is the required fix before the cooktop will operate normally.

A reset may temporarily clear the fault display, but C-82 will return if the underlying ventilation problem has not been corrected. Because the error is triggered by a real thermal condition rather than a software glitch, the sensor will detect the over-temperature state again as soon as the cooktop heats up under restricted airflow. Fix the installation or airflow issue first, then reset.
