Electrolux Range Error Code C-23

The C-23 code means the oven temperature has exceeded its safe operating limit and the control system has triggered an overheating fault. The appliance shuts down to prevent damage and protect against a safety hazard. The fault is associated with the broil, bake, and convection heaters and the relay circuitry on the sub PCB. The root cause must be identified and corrected before the oven will return to normal operation.

No, you should not attempt to use the oven while C-23 is displayed. This fault indicates the oven has already exceeded its safe temperature limit, which means a heating component or relay is likely not shutting off correctly. Continuing to operate the appliance in this condition could cause further component damage or create a fire hazard.

Repair costs vary depending on which component has failed. Replacing a single bake, broil, or convection heating element typically ranges from around $75 to $200 including the part and labor. If the sub PCB relay board needs replacement, costs can range from $150 to $400 or more depending on the specific board and labor rates in your area. Getting a diagnostic from a qualified technician will help identify exactly which component is at fault before committing to a repair.

Some parts of the diagnosis, such as visually inspecting the heating elements and checking for signs of burning or damage, can be done by a knowledgeable DIYer. However, resistance testing of the heaters and testing the DLB relays on the sub PCB requires a multimeter and comfort working with appliance internals after disconnecting power. If a relay on the sub PCB or the board itself needs replacement, many homeowners prefer to hire a qualified technician for that portion of the repair.

A power reset, such as unplugging the range or turning off the circuit breaker for a few minutes, may temporarily clear the fault display. However, if the underlying cause, such as a stuck relay or a shorted heating element, has not been repaired, the code will return as soon as the oven is used again and temperatures climb. A reset alone is not a fix.
