Kenmore Range Error Code 1c7c

The 1c7c code means the electronic control board has detected that an internal calibration value is outside of acceptable limits. The display shows 'CAL' in the time digit area to indicate this condition. The calibration data is stored within the control board itself and governs oven temperature management. Replacing the control board is the recommended fix.

Operating the range with an active 1c7c fault is not recommended. Because the calibration data is out of limits, the control board may not accurately regulate oven temperature, which could result in undercooked food or uncontrolled heating cycles. Discontinue use until the control board has been replaced.

The cost depends primarily on the price of the replacement control board and whether you hire a technician. Control board parts for Kenmore ranges typically range from $150 to $350 depending on the specific model. Adding professional labor, the total repair cost generally falls between $250 and $550. Doing the repair yourself eliminates the labor portion of that cost.

The repair requires replacing the electronic control board, which is a moderately advanced DIY task. You will need to disconnect power to the range, access the control panel, and swap the board while carefully transferring wire harness connectors. If you are comfortable working with appliance electronics and following a wiring layout, this is achievable without a service call.

A power reset may temporarily dismiss the displayed fault, but it will not correct the underlying issue. If the control board's calibration memory is corrupted or a board component has failed, the 1c7c code or the 'CAL' display will return after power is restored. A board replacement is required for a permanent fix.
