Dacor Range Error Code F0

The F0 code on a Dacor range means the control board has detected a shorted or jammed input device, most commonly the membrane switch keypad on the control panel. The board sees a persistent signal as if a button is stuck or continuously pressed. This can be caused by a failed membrane switch, damaged wiring, or moisture under the keypad. The range displays this fault to prevent responding to false input signals.

A reset by cutting power at the breaker may temporarily clear the F0 code, but if the underlying cause is a faulty membrane switch or shorted wire, the code will return once the range powers back up. A reset is a useful first diagnostic step to determine if the fault is intermittent or persistent, but it is not a fix for a hardware failure.

Repair costs depend on which component has failed. A replacement membrane switch typically falls in the range of $50 to $150 for the part alone. If a control board replacement is needed, parts costs can range from $150 to $400 or more. Adding professional labor, total repair costs can range from $150 to $500 or higher depending on the specific model and technician rates in your area.

In some cases, yes. Start by powering the range off at the breaker for a few minutes and powering it back on to see if the code returns. If it does, inspect the wiring harness connected to the membrane switch for visible damage or pinching. Replacing a membrane switch is a repair many experienced DIYers can handle, though working safely with the range fully disconnected from power is essential.

It is generally not recommended to operate the range while the F0 code is active, because a shorted or jammed input device could cause the control board to respond to unintended commands. The safest course of action is to power the range off at the breaker until the cause of the fault has been identified and corrected.
