LG Dishwasher Main Control Board EBR73739203 OEM Part

The principal power control board is a key element within LG and Sears-Kenmore dishwashers, residing internally to manage their operational functions. It interprets data from various sensors to confirm proper performance across all components. Should the control board encounter a fault, symptoms may include flickering lights, non-responsive buttons, or a complete halt in function.

Prior to replacing the control board, it is essential to disconnect the dishwasher from its electrical supply. For safety, wearing work gloves is advisable. To access the board, the inner door panel must be removed and the wiring harness detached. Subsequently, connect the harness to the new board and proceed with installation. Reassemble the dishwasher, ensuring the inner door panel is securely fastened, and conduct a functionality test to ensure proper operation.

This control board is specifically engineered for LG dishwashers and is provided directly by the manufacturer as a singular, authentic OEM replacement part. It effectively addresses issues such as an unresponsive touchpad.
