What C82 Means
Electric (radiant smoothtop) Cooktop: C82 is published as a cookware and overheating page. KitchenAid names two conditions - the pan or pot is not the right size, and the pan or pot is empty or has boiled dry - and then records that the surface cooking area has overheated and the automatic shutoff was activated. Its cookware guidance is specific: the diameter of the pan base should equal the size of the cooking area, a smaller pan should not be more than half an inch (1.3 cm) smaller than the area, and a larger one should not extend more than half an inch beyond it. Ideal cookware has a smooth flat bottom, straight sides, a well-fitting lid and medium-to-heavy thickness.
Common Causes of C82
- A pan or pot that boiled dry or was heated empty
- A pan base noticeably smaller or larger than the cooking area it was on
- Thin or warped cookware that does not sit flat on the glass
🔧 One Safe Check You Can Try
Turn every surface control off, turn the oven off if it is running, and wait five minutes for the cooktop to cool before touching the glass or the pan. Then look at what was on the ring: a pan that boiled dry is the single most common way to reach this code, and a pan far smaller than the element lets the exposed ring heat the glass rather than the food. Match the pan base to the cooking area within half an inch either way, never run one empty, and turn the cooktop back on once it has cooled.
⚠ Why You Shouldn't Go Further Than That
- A dry pan on a radiant ring can reach temperatures that damage the glass top itself, and a cracked ceramic top is a replacement rather than a repair.
- The shutoff that produced this code is a protection device, so a cooktop that keeps triggering it is being run in a way the glass is quietly paying for.
- If the code appears with correct cookware and a normal amount of food in it, the temperature limiting is reporting something that is not about the pan, and that wants measuring at the element.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
