Lg Refrigerator Control Board

The PCB Assembly, Main is an OEM part for LG refrigerators. This main control board, or printed circuit board (PCB), manages and coordinates all the refrigerator's functions, including temperature regulation, defrost cycles, and other essential operations. It acts as the brain of the refrigerator, ensuring efficient and effective performance.

Common causes of a bad PCB include electrical surges, manufacturing defects, or wear and tear over time. These issues can disrupt the refrigerator's normal functions and lead to various operational problems.

Symptoms of a bad PCB assembly include:

• The refrigerator not cooling properly
• Error codes displayed on the control panel
• Unresponsive or malfunctioning controls
• Inconsistent temperatures within the refrigerator compartments

This OEM LG part is also compatible with Sears/Kenmore models.

This power control board assembly regulates power and system functions for the appliance, restoring electronic control of lights, displays, and components when the original board fails. Replaces a failed main control board to recover normal operation. What it does:

• Manages incoming power and distributes voltage to displays, sensors, and motors
• Controls compressor, fan, and defrost cycles via signals to other modules
• Can cause blank displays, no power to lights, or intermittent operation when faulty
• May stop appliance functions like cooling if the board no longer responds

• Disconnect power to the appliance before starting any repair to avoid shock or damage
• Handle the board carefully and avoid touching components; use anti-static precautions if available
• Verify the board part number matches the one on the appliance before installation

This Main PCB Power Control Board Assembly manages the appliance's electronic control and power distribution so cycles run as programmed and functions respond to user commands. Replacing a faulty board restores proper control operation. What it does:

• Regulates power to motors, valves, sensors and user interface circuitry
• Interprets control inputs and runs timed cycles and functions
• Helps prevent erratic behavior caused by failed board components
• Common symptom link: unit won't start, touchpad unresponsive, random resets or error codes indicating control faults

• Disconnect power before accessing electrical components to avoid shock
• Ground yourself and handle the PCB by edges to reduce static risk
• Inspect connectors and harnesses for damage; seat plugs fully during reassembly
