JennAir Radiant Cooktop Code C82: Pan Size or an Empty Pot

What C82 means

C82 on JennAir electric radiant and touch-control cooktops, including JED3430GS-style models, points at the cookware rather than the cooktop. The pan or pot is the wrong size for the cooking area, or it is empty or dry. The cooktop needs a flat-bottomed utensil that matches the element to reach full wattage, so the display shows C82 and the heat output is held back.

Common causes of C82

A pan that is smaller or larger than the selected cooking area
An empty or dry pot left on a heated element
A warped, thin or rounded pan bottom that does not sit flat on the glass
A lid that does not fit and lets the contents heat unevenly

✓ One safe check you can try

1. Turn the element off and let the pan cool. 2. Pick a pan with a smooth, flat bottom, straight sides and a well-fitting lid. 3. Match the pan diameter to the circle of the cooking area you selected. 4. Add food or liquid so the pan is not empty. 5. Turn the element back on. If C82 appears with proper cookware, call us.

! Why to stop there

Many C82 messages end with a pan swap, so a repair visit could be wasted money.
Using a thin or warped pan can leave marks on the glass that no technician can reverse.
If the code stays with good cookware, the sensing circuit needs a real measurement, which is best done by a trained technician.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

C82C82 questions

What pan should I use with C82?

Choose a medium-to-heavy pan with a smooth flat bottom, straight sides and a lid that fits. The bottom should match the size of the cooking area you turned on.

Can an empty pot cause C82?

Yes. A pot that is empty or dry is one of the conditions behind this code. Turn the element off, let it cool, add contents and start again.

When is C82 a repair issue?

It is a repair issue when the code appears more than once with a correct, filled, flat pan on the matching cooking area. At that point we can inspect the cooktop and quote the price in writing first.
