This is a relay control board manufactured by Frigidaire to replace a broken or faulty part in wall ovens.In order for the appliance to work as intended, the relay control board needs to be able to receive signals from the main control board. It can then send relays that regulate the oven's various elements. Should this part be worn, faulty, or malfunctioning, the appliance won't work as intended, if at all, thus requiring replacement. To prevent injury, always wear work gloves and disconnect all power sources entirely from the appliance.This OEM relay control board is sold individually and manufactured from durable materials. It is compatible with wall ovens manufactured by various brands, including Frigidaire, Electrolux, Kelvinator, and Westinghouse.316443910 (AP3960187) replaces 1197132, AH1528195, EA1528195, PS1528195.
