What 1c1c means on a Jenn-Air oven

The 1c1c error code on a Jenn-Air oven indicates that the control panel has detected a shorted key condition, meaning one or more keys in the touchpad matrix are registering as continuously pressed. The control interprets this as a stuck or short-circuited key input and responds by disabling the audible feedback tone for key presses and locking out the affected key to prevent erratic or unsafe operation. This is a protective response built into the control logic to keep the oven from executing unintended commands.

The key matrix on a Jenn-Air oven control panel is a grid of conductive traces and membrane layers that register touches by detecting contact closures between layers. When a key is shorted, the two layers of the membrane are in constant contact at that point, either due to physical damage, liquid contamination, or a failed membrane assembly. The control continuously scans this matrix and, upon detecting a sustained closure that does not match a normal timed key press, flags the 1c1c fault.

Diagnosis should begin with a thorough inspection of the control panel key matrix. Look for signs of moisture intrusion, grease contamination, or visible damage to the membrane surface. If the membrane appears intact, the issue may lie in the ribbon cable connection between the keypad and the electronic control board, or in the control board itself interpreting a false signal. Separating the keypad from the control board and checking for continuity across key positions can help isolate whether the fault originates in the membrane or the board.

Common causes of 1c1c

  1. 01

    Damaged or failed touchpad membrane

    Part replacement

    The membrane keypad layers can stick together at a specific key location due to wear, impact, or delamination, creating a permanent contact closure that the control reads as a continuous key press. Inspect the keypad surface for bubbling, cracking, or any area that feels depressed.

  2. 02

    Liquid or grease contamination under the keypad

    Wiring / connection

    Moisture or cooking grease seeping beneath the membrane can bridge the conductive layers at a key position, simulating a shorted key. Check the edges and surface of the panel for any signs of fluid intrusion or residue.

  3. 03

    Loose or damaged ribbon cable connection

    Wiring / connection

    The ribbon cable connecting the touchpad membrane to the electronic control board can develop a poor connection or short if it is kinked, partially seated, or has damaged conductors. Inspect the cable and its connectors at both ends for visible damage or misalignment.

  4. 04

    Failed electronic control board

    Part replacement

    In some cases the control board itself may misinterpret input signals from the key matrix due to a failed input circuit or component on the board. This is less common but should be considered if the keypad and ribbon cable check out as undamaged.

  5. 05

    Foreign object pressing against the control panel

    Wiring / connection

    A pot, utensil, or other object resting against the touchpad can physically hold a key in the depressed position. Verify nothing is in contact with the control panel before proceeding with further diagnosis.

Frequently asked questions about 1c1c

What does 1c1c mean on a Jenn-Air oven?
The 1c1c code means the oven control has detected a shorted key on the control panel, where one key is being read as continuously pressed. The control responds by disabling the audible tone for key presses and locking out the affected key. This is a protective measure to prevent unintended commands from being executed. The fault typically points to a damaged touchpad membrane, contamination, or a wiring connection issue.
Can I fix the 1c1c error myself?
Some causes of the 1c1c error are DIY-friendly. Start by confirming nothing is physically pressing against the control panel, then inspect the keypad surface for visible damage or moisture. If the membrane is contaminated, careful cleaning of the panel area may resolve it. However, if the touchpad membrane or control board needs replacement, that work requires disconnecting electrical components and is best suited for technicians or experienced DIYers comfortable working with oven electronics.
Is it safe to use my Jenn-Air oven when the 1c1c code is showing?
You should avoid using the oven while this fault is active. A shorted key can cause the control to receive unintended inputs, which could result in incorrect cooking functions or temperatures being activated. The control does disable the affected key as a precaution, but the underlying fault should be resolved before relying on the appliance for normal cooking use.
Will resetting the oven clear the 1c1c error code?
Resetting the oven by cycling the power at the breaker may temporarily clear the 1c1c code, but it will return if the underlying cause is not corrected. If the shorted key condition still exists in the membrane or wiring, the control will detect it again on the next scan cycle and re-flag the fault. A lasting fix requires identifying and correcting the physical cause of the short.
How much does it cost to repair a Jenn-Air oven showing the 1c1c error?
Repair costs depend on which component is at fault. A replacement touchpad membrane or keypad assembly typically ranges from $50 to $200 for the part alone. A new electronic control board can range from $150 to $400 or more depending on the model. Adding professional labor, total repair costs generally fall between $150 and $500. Getting a diagnostic assessment from a qualified technician before purchasing parts is recommended.
