What 1c1c means on a Kenmore range

The 1c1c error code on a Kenmore range indicates a key press error within the touchpad and control board system. When this fault is detected, the control module identifies that one or more keys on the keypad are registering a continuous or stuck signal. In response, the control disables the buzzer associated with the affected key to prevent continuous alarm sounding. This is a protective measure built into the control logic to alert the technician or user that the input system is not functioning correctly.

The keypad on these ranges communicates with the control board through a ribbon cable or direct wire harness connection. When a key membrane becomes stuck, contaminated, or shorted, it sends a persistent signal to the control board that mimics a key being held down. The control interprets this as an error condition rather than a valid input, triggering the 1c1c fault. Moisture intrusion, food debris under the keypad surface, and physical damage to the membrane are the most common root causes.

The first diagnostic step is to inspect all connections between the keypad and the control board. A loose or corroded ribbon cable connector can cause false key press signals identical to those produced by a physically stuck key. If the connections are secure and undamaged, the keypad membrane itself should be tested and inspected for damage, followed by evaluation of the control board if the keypad checks out normal.

Common causes of 1c1c

  1. 01

    Stuck or contaminated keypad key

    Part replacement

    Food residue, grease, or moisture trapped under a keypad button can cause a key membrane to remain depressed or short against adjacent contacts, producing a continuous key press signal. Inspect the keypad surface for visible contamination or physical deformation around individual keys.

  2. 02

    Loose or damaged keypad ribbon cable connection

    Wiring / connection

    The ribbon cable connecting the keypad to the control board can become loose, bent, or corroded over time, causing erratic or false key signals. Check the connector at both ends for proper seating and signs of corrosion or physical damage.

  3. 03

    Failed keypad membrane

    Part replacement

    The membrane switch layer inside the keypad can crack or delaminate, creating an internal short that mimics a held key press. If the keypad surface appears undamaged externally but the error persists after cleaning and reseating connections, the membrane assembly likely needs replacement.

  4. 04

    Moisture intrusion into the keypad or control area

    Wiring / connection

    Spills or steam exposure can introduce moisture into the keypad or behind the control panel, causing key contacts to bridge and trigger a false key press error. Allow the control area to dry completely and inspect for corrosion on contacts.

  5. 05

    Faulty control board

    Part replacement

    If the keypad and all connections test normal, the control board itself may have a failed input circuit that incorrectly reads a key as continuously pressed. This is the least common cause and should be diagnosed only after ruling out the keypad and wiring.

Frequently asked questions about 1c1c

What does 1c1c mean on a Kenmore range?
The 1c1c error code on a Kenmore range indicates a key press error, meaning the control board has detected that one or more keypad buttons are registering a continuous or stuck input signal. In response, the control disables the buzzer for the affected key to prevent constant beeping. The fault points to a problem in the keypad, the wiring connections between the keypad and control board, or less commonly, the control board itself.
Can I fix the 1c1c error on my Kenmore range myself?
In many cases, yes. Start by disconnecting power to the range for a few minutes, then check that the ribbon cable connecting the keypad to the control board is fully seated and free of corrosion. Clean the keypad surface carefully to remove any debris or moisture that could be causing a key to stick. If these steps do not resolve the error, the keypad membrane or control board may need to be replaced, which requires ordering the correct replacement parts for your specific model.
Is the 1c1c error on a Kenmore range a safety hazard?
The 1c1c error itself is not a direct safety hazard, but it does indicate that the control panel is not operating normally. A stuck key could potentially cause unintended operation of oven functions. Until the fault is resolved, monitor the range closely and avoid leaving it unattended during operation.
Will resetting my Kenmore range clear the 1c1c error code?
A power reset by unplugging the range or switching off the circuit breaker for several minutes may temporarily clear the 1c1c code. However, if the underlying cause such as a stuck key, damaged keypad membrane, or faulty connection is not corrected, the error will return. A reset is useful as a first step to confirm whether the issue is intermittent or persistent.
How much does it cost to repair a Kenmore range showing the 1c1c error?
Repair costs vary depending on which component needs replacement. A replacement keypad membrane or touchpad assembly typically costs between $30 and $120 in parts, depending on the model. A replacement control board can range from $100 to $300 or more. If you hire a technician, expect to add labor costs of roughly $75 to $150 per hour on top of parts.
