Lg Washer Control Board

The Noise Filter Assembly is an OEM part for LG washing machines, designed to minimize electrical noise interference within the appliance. This essential component ensures that the washer operates smoothly without emitting disruptive sounds that can affect both the performance of the washer and the comfort of your home environment. 

Causes of a bad Noise Filter Assembly can range from wear and tear over time to exposure to power surges or electrical spikes, which can damage the internal components of the filter. 

Symptoms of a bad Noise Filter Assembly include:

• Increased electrical noise or buzzing sounds emanating from the washer
• Intermittent disruptions in the washer's performance
• The washing machine failing to start or experiencing power fluctuations

This OEM LG part is also compatible with some Kenmore models.

This noise filter assembly conditions incoming AC power to reduce electromagnetic interference before it reaches the control system. A failed line filter can cause no power, intermittent shutdowns, or breaker trips; replacing restores stable, reliable operation. What it does:

• Filters EMI/RFI on the power line to help protect sensitive control electronics
• Helps prevent interference that can cause no power, flickering display, or random resets
• A failing filter may trip a breaker/GFCI when the unit is plugged in or starts a cycle
• Visual clues can include scorch marks, burnt odor, or a cracked/bulged filter body

• 1 noise filter assembly

• Disconnect power before servicing; verify the outlet is de-energized
• Access is typically near the power cord entry behind a rear/top panel (varies by model)
• Label or photograph wire positions and transfer connections one by one; secure the ground
• Mount firmly and route wires to avoid pinching; reassemble and test for proper operation

• Line filter, EMI filter, RFI filter

This PCB assembly is the appliance's main control board that manages electronic functions and user-interface signals, restoring proper control and communication between sensors, motors, and the display so the appliance operates as intended. What it does:

• Routes power and control signals to motors, valves, sensors and the user interface
• Interprets inputs from buttons, dials or touch controls and runs selected cycles
• Helps prevent incorrect operation caused by faulty electronics
• Common symptoms: no power to controls or display, unresponsive buttons, error codes, or intermittent operation

• Disconnect power before servicing to avoid shock or damage
• Handle by the edges and avoid touching components; observe ESD precautions
• Confirm correct board PN and orientation before installing; some boards require bracket or connector transfer
• If symptoms persist after replacement, check wiring, connectors and related sensors

This power control board is the appliance's main electronic PCB. It manages power distribution and control logic, coordinating sensors and user inputs so the unit's motors, fans, heaters, and valves run when they should. What it does:

• Distributes and regulates power to key components through onboard relays
• Processes sensor feedback and timing to execute programmed operations
• Coordinates operation of motors, fans, heaters, and valves as required
• Common failure symptoms: unit won't power on or start, unresponsive controls/display, intermittent or erratic operation, repeated clicking from the control area, or error codes

• 1 electronic control board assembly

• Disconnect power before servicing; verify power is off
• Use ESD protection and handle the board by the edges
• Photograph/label connectors and transfer plugs one at a time, ensuring proper seating and orientation
• Secure the board, reassemble covers, restore power, and verify normal operation

The PCB Assembly Main is an OEM part for LG washing machines. As the central control unit, this printed circuit board regulates all functions of the washer including cycle selections, temperatures, spin speeds, and diagnostic systems.

Causes of a bad main PCB include natural wear and tear over time, moisture damage, power surges, or fluctuations that compromise electronic components. 

Symptoms of a failed PCB assembly include:

• The washer not starting or powering on at all  
• Inability to select or change wash cycles
• Error codes displayed
• No response from control buttons and displays

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