The Main Control Board is an OEM component specifically designed for LG dishwashers. This board is the "brain" of the dishwasher, utilizing built-in programs to operate all functions of the unit including wash cycles, heating elements, motor control, and more.
Symptoms of a bad main control board can include intermittent or complete failure of wash cycles to run properly, inability to select certain options or unresponsive touch controls. Over time, electronic components are susceptible to damage from electrical surges or failures in associated parts.
Symptoms of a bad main control board include:
- Dishwasher fails to start or run cycles
- Inability to select options via touch controls
- Display/interface errors such as flickering lights
- Strange sounds coming from internal components
This OEM LG part is also compatible with Sears/Kenmore. Replacing the main control board can help restore full functionality to your LG dishwasher.
