Dacor Range Oven Cooktop Error Code F14

The F14 error code on a Dacor Discovery Range signals an EPROM failure within the control panel. EPROM stands for Erasable Programmable Read-Only Memory, a type of non-volatile memory chip embedded on the control board that stores the appliance's operating firmware and calibration data. When this chip fails or loses the ability to reliably read or write data, the control system cannot function properly and triggers the F14 fault to alert the technician to a fundamental board-level hardware failure.

This type of failure is almost always rooted in the power board itself rather than a wiring or sensor issue. The EPROM chip is soldered directly onto the control board, meaning it cannot be replaced as a standalone component in the field. Power surges, voltage spikes, or prolonged exposure to heat over time can degrade the memory chip or the board circuitry supporting it, causing the stored firmware to become corrupted or the chip to fail entirely. In some cases, a momentary power interruption during a write cycle can also corrupt EPROM data.

Because the EPROM is integral to the power board assembly on Dacor Discovery Range units, the correct repair procedure is to replace the entire power board. Attempting to reset or cycle power may temporarily clear the display, but the fault will return if the underlying board hardware has genuinely failed. A technician should also inspect the incoming power supply for signs of voltage irregularities before installing a replacement board, to reduce the risk of the new component being damaged by the same root cause.
