Frigidaire Range Error Code 1c7c

The 1c7c code means the electronic oven control failed its internal calibration routine three consecutive times and detected that the calibration value was outside its acceptable range. When this happens, the control displays 'CAL' in the time digits and disables all oven cavity outputs. The oven will not heat until the fault is resolved. A Power On Reset is required to restore normal operation after the underlying cause is addressed.

The oven cavity is not safe to use while this code is active because the control has deliberately disabled all heating outputs for the oven. The cooktop burners on a gas range may still function, but the oven should not be operated until the fault is diagnosed and cleared. Do not attempt to bypass the control's shutdown behavior.

If only a Power On Reset is needed, there is no parts cost. If the oven temperature sensor needs replacement, parts typically range from $20 to $60 depending on the model. Replacing the electronic oven control board is the most expensive scenario, with parts generally ranging from $150 to $350 or more, plus labor costs if a technician performs the repair.

A Power On Reset, performed by unplugging the range or switching off the circuit breaker for several minutes, is required to bring the oven out of its locked-out state. If a transient power event caused a temporary calibration data corruption, the reset may fully clear the fault. However, if the control board or another component has a hardware fault, the error will return after reset and further diagnosis or repair will be needed.

Start by performing a Power On Reset: disconnect power to the range for at least five minutes, then restore power and check if the error returns. If it clears and stays clear, a transient power event was likely the cause. If the fault returns, inspect the wiring harness connections at the control board and check the oven temperature sensor for damage or loose connections. If no wiring faults are found, the electronic oven control board will likely need to be replaced.
