Williams P625469 Control Board 4-Relay with Transformer 120V

The Williams Comfort Products P625469 is an OEM replacement control board designed for use in Williams gas furnaces and wall heaters. This board integrates four relays and an onboard transformer, operating on 120V AC, to serve as the central electrical command hub for compatible heating systems.

The integrated transformer steps down line voltage to supply low-voltage control circuits, while the four relay outputs manage key system functions such as the blower motor, gas valve, igniter sequencing, and auxiliary equipment. Replacing a faulty control board with this genuine OEM part restores reliable, manufacturer-specified system operation.
