Dacor Range, Oven, Cooktop Error Code F14

F14 on a Dacor Discovery Range indicates an EPROM failure, which is a memory chip failure on the control panel's power board. The EPROM stores the operating firmware and calibration data needed for the appliance to function. When this chip or the board circuitry supporting it fails, the control system cannot operate and displays the F14 fault. Replacing the power board is the prescribed repair.

A power reset may temporarily clear the F14 error from the display, but the fault will return if the power board's EPROM has genuinely failed. Resetting does not repair damaged or corrupted memory hardware. If F14 comes back after a reset, board replacement is necessary.

Repair costs for an F14 fault primarily involve the price of the replacement power board plus labor if a technician is hired. Power board parts for Dacor Discovery Range units can range from roughly 150 to 400 dollars depending on availability and the specific model. Labor costs for a qualified appliance technician typically add another 100 to 200 dollars, bringing total repair estimates to approximately 250 to 600 dollars in most cases.

Replacing the power board is a repair that a skilled DIYer can perform, but it involves working with the electrical components of the appliance and requires disconnecting power before starting. The EPROM chip itself is soldered to the board and cannot be replaced separately, so the entire power board assembly must be swapped out. If you are not comfortable working with appliance electronics, hiring a qualified technician is the safer option.

A control panel failure indicated by F14 means the board cannot reliably manage appliance functions, which can include temperature regulation and safety shutoffs. Continuing to use the range while this fault is active is not recommended. The appliance should be taken out of service until the power board is replaced.
