Short answer first
C82 means the surface cooking area got too hot and the automatic shutoff cut in, according to Jenn-Air's documentation. Let the surface cool fully; most often the cause is the pan or the way the area was used, and a repeat with normal cookware points at the surface control.
Error codes
Reference| Code | Meaning |
|---|---|
| C82 | The surface cooking area has overheated and the automatic shutoff was activated. |
Signs that come with the code
- Cookware rocks on the surface — A pan that does not sit flat leaves heat in the surface.
- The cooking area stops heating mid-cook — The shutoff cuts heat even though the control is still set.
- The surface looks discolored around the area — Overheating can leave a rainbow or scorch mark.
- NEAR MISS: an oven cavity overheat code — Oven overheat codes concern the cavity, not the surface cooking area.
Likely causes, ranked
- Long high-heat cooking with oversized pots — Ranked first when C82 appears during long, high-heat cooking such as canning: heat held against the surface for a long time can reach the shutoff without any part being faulty.
- Warped or poorly matched cookware — A pan that does not sit flat, or is much smaller than the cooking area, leaves heat in the surface instead of the food.
- Something covering the surface — Foil, a baking sheet or a griddle resting across the cooking area traps heat beneath it.
What to check first, and why
- Recall what was cooking — A pan left on, a large pot on high or nothing at all: each points at a different cause.
- Let the surface cool fully — Switch the cooking area off and wait until the surface is cool before anything else.
- Look for anything on the surface — Remove foil, sheets, griddles or utensils resting on the cooktop.
Clearing the code and safe checks
- Switch the area off and move the pan — Turn the cooking area off and lift the pan away, using oven mitts.

- Wait until the surface is cool — Leave the cooktop alone until it is cool to the touch.
About 30 min
- Cook at a lower setting — Bring large pots up to heat, then turn down; long periods on high invite another shutoff.
About 2 min
- Stop before any panel comes off — Everything past this point needs live measurements or a panel removed; that is the line between an owner check and a service call.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. An overheated cooktop stays hot well after the code appears: keep hands and towels away, never cool it with water, and smother a pan fire with a lid rather than water. If the range or oven has to come forward, use two people: it is heavy, and a range is held by an anti-tip bracket that must be re-engaged when it goes back.
Reset or service call?
Call for service if C82 returns with a flat, matched pan of water on a medium setting, or if a cooking area heats with its control off. Both point at the surface control or the limiter rather than the cookware.

Generalized information
Scope: the documented meaning of C82 for Jenn-Air ranges and cooktops whose code list carries C82 as a surface overheat. Out of scope: oven cavity temperature codes, and models that read C82 differently; so is model-level detail such as connector positions and part numbers. A model-specific page, where one exists, is the more precise source.
