The LG EBR74164814 Range Oven PCB Relay Control Board Assembly manages electrical signals for key oven operations. This electronic component uses relays to switch power to connected heating elements and other oven functions according to the settings selected through the appliance controls. Installed within the range oven’s control system, the board receives electrical commands and directs power to the proper components at the required times. It supports coordinated heating operation and consistent cycle performance. Replacing a damaged control board can restore proper electrical switching and oven operation when the existing part no longer operates correctly. This assembly is designed for compatible range oven models and should be checked against the appliance model before installation.
