Washer Suppression Parts

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.

EMI filter reduces electrical noise on the appliance's incoming power line to help protect electronic controls and cut down on radio/TV interference. It restores proper power filtering for appliances that show noise-related control issues. What it does:

• Filters electromagnetic and radio-frequency interference on the power input to prevent electrical noise from affecting control boards and sensors.
• Helps reduce visible or audible interference with nearby electronics such as radios, TVs, and audio equipment.
• Can address intermittent control errors, unexpected resets, or erratic operation linked to line noise.
• Provides the correct connection point for the appliance's power input so the control circuitry receives cleaner power.

• Disconnect power at the breaker and unplug the appliance before starting any work. Verify power is off with a tester.
• Match wiring colors and terminal types; secure all connections and route wires clear of moving parts.
• Some installations require removing access or control panels—retain fasteners.

This power line filter sits between household AC and the washer's internal wiring to reduce electrical interference and help stabilize control operation. Replacing a failed filter may restore power and prevent nuisance breaker or GFCI trips.

• Filters incoming AC power to reduce electromagnetic interference reaching the control and motor circuits
• Helps prevent interference-related issues like erratic controls or random resets
• Failure may present as no power/blank display, intermittent power loss, or tripping a breaker/GFCI
• Visual clues of failure can include scorching, swelling, or a cracked housing

• Unplug the washer or switch off the circuit breaker before servicing; allow a few minutes for internal components to discharge
• Access the filter location (often near the control area or rear panel) per your model's service information
• Note wire locations (LINE, LOAD, and GROUND) and move one lead at a time to avoid miswiring
• Mount securely and ensure the ground connection to the cabinet is tight for proper operation
