JennAir Range Code 1c7c: Oven control or wiring problem

What 1c7c means

On JennAir electric, gas and dual-fuel ranges with electronic oven control, such as the JES1750FS and JDS1750ML, 1c7c is the last of the lowercase oven-control codes in this group: there may be a problem with the oven control or the associated wiring. The oven stops and the display shows 1c7c. If a reset clears it, it may have been a power event, but one that returns needs a technician.

Common causes of 1c7c

Oven control board with an internal problem
Wiring harness with a loose connector
Power event that interrupted the control

✓ One safe check you can try

1. Press Cancel. 2. Wait until the oven is cool. 3. Turn the breaker off for a minute, then back on. 4. Try a 350 degree bake for ten minutes. 5. If 1c7c returns, stop and call us. Gas ranges: with any gas smell, leave the house and call the gas utility from outside.

! Why to stop there

Repeated codes after a reset point to hardware.
Safe testing needs the range powered with covers off.
We quote first in writing and warrant work for 30 days.

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.

1c7c1c7c questions

Is 1c7c different from 1c6c?

The official description is identical, and we treat them the same way during diagnosis. Both lead to the oven control and its wiring first, and the numbers just mark different checks.

Why did it appear after a storm?

Storms cause power surges that can upset a control, and a reset may clear it. If it returns without another storm, a part is likely failing and needs testing by a technician.

What if it comes back every day?

Then a part is probably failing, so book a visit and mention how often it happens and what the oven was doing. That detail speeds up the repair.
