JennAir Range Code 1c1c: Keypad circuit problem

What 1c1c means

On JennAir electric, gas and dual-fuel ranges with electronic oven control, such as the JES1750FS and JDS1750ML, 1c1c is a lowercase code that means there may be a problem with the user interface or keypad, or the wiring connected to it. The control cannot read the panel properly, so keys may be ignored or the oven may stop. The code appears on the display and may stay until power is cycled.

Common causes of 1c1c

User interface or keypad with a failing contact
Wiring between the panel and the control
Moisture on or behind the panel

✓ One safe check you can try

1. Press Cancel and wipe the panel with a barely damp cloth. 2. Dry it fully. 3. Switch the breaker off for one minute and on again. 4. Tap one key at a time and check the display. If 1c1c comes back, leave the panel alone and call us.

! Why to stop there

Panel damage is often invisible from the front.
Control and panel wiring need a test, not a guess.
We quote in writing first 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.

1c1c1c1c questions

Is 1c1c written with lowercase c on purpose?

Yes. The display shows it that way, and we keep the code exactly as displayed so you can match it to this page. The same goes for the other lowercase c codes in this group.

Can cleaning cause 1c1c?

Too much liquid on the panel can cause it, so use a barely damp cloth next time and dry the panel before switching the range back on.

Will you replace the keypad?

Only if testing shows it is the cause, and we quote the price in writing before ordering anything. The wiring behind the panel is checked first, since a loose ribbon can mimic a bad keypad.
