Straight to it
C82 on an oven of this generation means the cooktop protected itself by shutting the cooking area down after it overheated. You can cook on the other areas, and this one comes back after a cool-down unless the cause is still there.
What this code is documented as meaning
Reference| Code | Documented meaning |
|---|---|
| C82 | The surface cooking area has overheated and the automatic shutoff was activated. |
What the appliance does alongside the code
- One cooking area stopped mid-use and shows the code — The others carry on, which is the signature of a per-area shutoff.
- It happens with an empty pan or a boil-dry — Nothing absorbs the heat, the surface temperature runs away, and the shutoff operates.
- NEAR MISS - every area is dead at once — All areas out together is a supply or board fault, and it is a different page.
Causes in the order they actually occur
- A dry, empty or badly matched pan — Ranked first because it is by far the commonest and costs nothing: without food or liquid to take the heat away, the surface reaches its limit in minutes.
- Ventilation under or around the cooktop being blocked — Third: a cooktop over a packed drawer or an oven vent has nowhere to lose heat.
The check order this code implies
- Let everything cool and try again with a full, flat pan — Free, and it settles the commonest cause outright.
- Look at what is packed under and around the cooktop — Blocked ventilation turns a normal session into an overheat.
What an owner can safely do
- Cook the same thing again with a flat, full pan matched to the area — If it behaves, the pan was the fault and no part is needed.
About 20 min
- Clear whatever is packed under or beside the appliance — Ventilation is part of the installation, not an optional extra.
About 10 min
- STOP HERE if it repeats with a good pan — Unplug the appliance or switch off its breaker before any panel comes off; a capacitor can hold a charge after the power is off.
What to do before any panel comes off
Safety
Let everything cool. A surface that has just tripped its own shutoff is at the top of its temperature range, and the glass gives no warning. Do not cool it with water.
When a reset is not the answer
Call when the area shuts down with a flat, full, correctly sized pan and clear ventilation: that is the sensing or switching circuit for that area and it is a service part. One exception to the order above, because it is about safety rather than cost: call straight away if the glass is cracked or the area stays hot after it is switched off.

The scope of this reading
This reading is written for the cooktop and range model lines that shut a cooking area down on temperature, and it stays with the code in its title. What is deliberately not here: the resistance tables, wiring colours and part numbers that differ between model lines, all of which belong to the service documentation for a specific unit rather than to a page about a code. If a page exists for your exact family or model, that page is the more specific answer and it should be read first; the code index linked below is where those pages are listed.
