JennAir Range Code 1c4c: Oven control reading

What 1c4c means

On JennAir electric, gas and dual-fuel ranges with electronic oven control, such as the JES1750FS and JDS1750ML, 1c4c means there may be a problem with the oven control or the associated wiring. The letters in these lowercase codes identify the check the control was running when it stopped. Here the control reports a problem and the oven halts the cycle with 1c4c on the display.

Common causes of 1c4c

Oven control that stops responding once it warms
Wiring or connector trouble to the control
Temporary upset after a power event

✓ One safe check you can try

1. Press Cancel and wait for the oven to cool. 2. Turn the range off at the breaker for one minute. 3. Turn it on and set the clock. 4. Bake briefly to test. If 1c4c returns, keep the oven off and call us.

! Why to stop there

The same description covers several causes, so we test.
Control boards are costly, so we confirm before ordering.
Price is written down first and repairs are warranted 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.

1c4c1c4c questions

What does the c in 1c4c stand for?

It is part of the displayed code, and we keep it exactly as shown so you can match it to this page. We do not translate the letters, because the official description covers the whole code.

Could a loose plug cause it?

Yes. Wiring is part of the official description, and a plug can work loose with repeated heating and cooling. We check connectors before any board is replaced.

How long is the visit?

Often one visit is enough to diagnose. If a part is needed, we quote it in writing and schedule the return at a time that suits you.
