Dacor Range Error Code F1

F1 on a Dacor range indicates a System Watchdog Circuit alarm, meaning the ERC self-diagnostic circuitry has detected a failure in the bake/broil system. The fault can originate from the ERC board, the relay board, the membrane touchpad, the bake or broil heating elements, or the wiring connecting these components. The range's control system uses this code to flag that something in the heating circuit is outside of expected parameters.

No, you should not attempt to use the oven while F1 is active. The watchdog alarm indicates a detected failure in the bake/broil system, and the control board has flagged the system as unreliable. Continuing to operate the range risks potential overheating, electrical faults, or damage to other components. The oven should remain off until the fault is diagnosed and repaired.

Repair costs depend heavily on which component is at fault. Replacing a membrane touchpad typically falls in the range of $100 to $250 for the part alone. A relay board replacement can range from $75 to $200, while an ERC board is often the most expensive component, potentially ranging from $200 to $500 or more depending on the model. Adding professional labor to any of these parts costs will increase the total, and getting a diagnostic estimate before committing to a repair is advisable.

The first diagnostic step, disconnecting the membrane touchpad from the ERC and observing whether the alarm clears, is something a technically confident DIYer can perform. However, further diagnosis requires an ohm meter and knowledge of how to safely test components like heating elements and relay boards in a high-voltage appliance. If the fault points to the ERC or relay board, replacement of those components is typically required and professional service is recommended for safety.

Resetting the range by cycling the power at the breaker may temporarily clear the F1 display, but the alarm will return if the underlying fault is still present. The ERC watchdog circuit will redetect the problem during normal operation or self-diagnostics. A reset is useful for confirming whether a fault is persistent or intermittent, but it is not a repair solution.
