Dacor Range, Oven, Cooktop Error Code F15

F15 on a Dacor Discovery Range indicates that the watchdog circuit on the power board has been detected as defective. The watchdog circuit is a built-in safety mechanism that monitors the main processor to ensure the electronics are functioning correctly. When this circuit fails, the range generates the F15 code to alert the user and technician. The power board must be replaced to resolve this fault.

Operating the range with an active F15 fault is not advisable. The watchdog circuit is a safety monitoring function, and its failure means the power board cannot reliably detect or recover from processor faults or control malfunctions. Continued use under this condition carries risk, and the appliance should remain off until the power board is replaced.

A power reset, such as cycling the circuit breaker or unplugging the range, is unlikely to permanently clear the F15 error because the code points to a hardware defect in the power board's watchdog circuit. The fault may clear temporarily after a reset, but it will return once the range detects the defective circuit again during operation. The underlying issue requires power board replacement to be fully resolved.

The repair for F15 requires replacing the power board, which involves working with high-voltage components inside the appliance. A knowledgeable DIYer comfortable with appliance electronics can perform this repair, but the range must be fully disconnected from power before any work begins. If you are not experienced with appliance electrical repairs, it is recommended to have a qualified technician perform the replacement.

The cost to resolve an F15 error primarily involves the price of a replacement Dacor power board, which typically ranges from around $150 to $400 or more depending on the specific model and parts availability. If you hire a technician, labor costs will add to that total, generally ranging from $80 to $200 depending on your location and service provider. Obtaining a repair estimate before authorizing work is always a good practice.
