JennAir Wall Oven Code 1c8c: oven control circuit alert

What 1c8c means

The code 1c8c on a JennAir built-in wall oven, such as the JJW2830DS or JJW9830DDP, signals a possible problem with the oven control or its wiring. The control is the board that manages heat and safety checks, and it has flagged something in its own circuit. You will see 1c8c on the display, and the oven may stay off. The same code is listed for combination ovens that include a microwave.

✓ One safe check you can try

1. Press Cancel and wait a moment. 2. Switch the breaker off for two minutes. 3. Restore power and try one short bake at low temperature. 4. If 1c8c is displayed again, stop and phone us. Keep the door closed while the oven rests, and avoid pressing keys repeatedly during the restart.

! Why to stop there

Control problems of this kind tend to repeat, and each repeat can stop a meal midway.
Testing needs a meter and access behind the oven.
We price the repair in writing before starting, and our work carries a 30-day warranty.

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.

1c8c1c8c questions

Why is the last character a letter in 1c8c?

The control uses a mixed set of characters to label its checks. The letter is part of the code exactly as it is shown, and we treat it the same way as the numeric ones.

Can a loose plug at the wall cause 1c8c?

Built-in ovens are hard-wired, so there is no plug to loosen. A loose terminal at the supply is possible, which is one reason we test power and the control together.

Is there anything I can clean to fix 1c8c?

No. Cleaning the panel or cavity will not affect a control problem. A reset is safe to try once, and a technician should handle the rest.
