Dacor Range Error Code F8

F8 on a Dacor range is a door locking switch alarm. It means the door lock motor ran for two minutes during a self-clean cycle without the phase switch confirming that the door had successfully locked. The oven shuts down and displays the code to prevent starting a self-clean cycle with an unsecured door. The issue typically points to a faulty switch, wiring problem, or a mechanical obstruction in the lock assembly.

Normal baking and cooking functions may still be available while the F8 code is active, since this fault specifically relates to the self-clean door lock system. However, you should not attempt to run the self-clean cycle until the fault is resolved, as the door lock is a safety mechanism required for that mode to operate. If the oven is completely unresponsive, discontinue use and have it inspected before cooking.

Repair costs depend on which component has failed. Wiring repairs or connector fixes are typically on the lower end of the cost spectrum. Replacing a door lock switch or phase switch generally falls in the range of $50 to $150 in parts, plus labor if a technician is used. A complete door lock motor assembly replacement on a Dacor range can run $100 to $300 or more in parts, with total repair costs including labor often ranging from $150 to $400 depending on your location and service provider.

Some causes of the F8 code are DIY-friendly, such as clearing debris from the door latch area or reseating a loose wiring connector. However, testing the phase switch for continuity, inspecting wiring harnesses, and replacing the lock motor or switch assembly require basic electrical diagnostic skills and comfort working around appliance components. If you are not confident performing these checks, a qualified appliance technician is recommended.

Resetting the oven by cycling the breaker or clearing the code from the control panel may temporarily clear the F8 display. However, if the underlying cause, such as a faulty switch, wiring issue, or mechanical obstruction, is not corrected, the code will return the next time self-clean mode is initiated. A reset alone is not a repair.
