Product Overview
LG Refrigerator Main Control Board EBR87145173
The EBR87145173 main control board is the central computer of the LG refrigerator.
It controls the compressor, evaporator fan, condenser fan, defrost heater, and temperature regulation system.
When this board begins to fail, the refrigerator may appear to have multiple problems even though only one component is defective.
Common Problems This Part Fixes
-
Refrigerator not cooling
-
Freezer warm or thawing
-
Compressor not starting

Repeated clicking from rear of unit
-
Fans not running

Unit stuck in defrost cycle

If your refrigerator turns on but does not cool properly, the main control board is one of the most commonly failed components.
How the Control Board Fails
Power surges, heat, and age can damage internal relays or voltage regulation circuits.
Because this board manages the entire cooling system, failure often looks like a sealed-system or compressor issue even when those parts are good.
