Lmxs30746s00 Parts

The Electronic Control Board is an OEM replacement part for LG refrigerators. As the "brain" of the refrigerator, it regulates power distribution, cooling functions, dispensers, lights and more based on internal algorithms and external triggers.

Symptoms of a bad electronic control board include:

• The refrigerator failing to cool properly or ice maker not operating  
• Lights, water/ice dispensers malfunctioning or unresponsive
• Control displays showing error messages or abnormal readings  
• Strange noises or smells coming from the refrigerator

Causes can be long-term moisture exposure leading to short circuits, voltage fluctuations over many cycles, or natural failures in the printed processor chip.

This LG electronic control board replacement is also compatible with select Sears/Kenmore models.

This sub PCB assembly is an electronic control board that processes inputs and switches components, coordinating specific appliance functions. Replacing a failed board can restore normal operation and resolve dead controls, error codes, or intermittent, unpredictable behavior. What it does:

• Distributes and regulates control power and switches loads via onboard relays/triacs
• Interprets signals from sensors and the user interface to execute commands
• Coordinates timing and operation of related components per the appliance's program logic
• Failure may present as no power, won't start, unresponsive or flickering display, random beeps, or recurring error codes

• 1 sub PCB assembly

• Disconnect power to the appliance before servicing; verify no voltage is present
• Use ESD protection and handle the board by the edges
• Photograph wiring; transfer connectors one at a time and ensure they are fully seated
• Secure the board with existing fasteners/standoffs; perform any required reset or diagnostic per your model's service info

This gas valve assembly controls and shuts off the flow of gas to your appliance's burner system, enabling safe ignition and steady heat. Replacing a sticking or failing valve restores reliable heating performance and consistent flame control.

• Regulates gas flow to the burner(s) as commanded by the control/thermostat
• Works with the igniter to light the flame
• Helps maintain stable gas supply for consistent heating
• Failure symptoms include no ignition, igniter glowing with no flame, intermittent heat, or a weak/uneven flame

• Disconnect power and shut off the gas supply before servicing
• Allow the appliance to cool and work in a well-ventilated area
• Transfer any fittings or brackets from the original valve if required
• After installation, restore gas and check all connections for leaks with a soapy-water solution

Glass Shelf provides a flat, easy-to-clean storage surface inside your refrigerator, replacing cracked or broken shelves to restore usable storage and help keep food and containers organized and supported. What it does:

• Note the order/orientation of any shims or washers and transfer them during reassembly
• Start threads by hand to avoid cross-threading; tighten securely without overtightening

This compressor damper is a vibration-isolating mount that sits between the sealed-system compressor and the chassis. It cushions the compressor to reduce noise, limit vibration transfer, and help keep refrigerant lines from being stressed.

• Isolates the compressor from the frame to absorb start/stop shock and vibration
• Helps reduce humming, rattling, or buzzing from the back/bottom of the appliance
• Replaces a damper that's cracked, flattened, hardened, or missing
• Can help if the compressor rocks or the unit vibrates excessively

• Disconnect power and pull the unit forward for access; remove rear/service panel if present
• Support the compressor to relieve load on the mounts before removing fasteners
• Match orientation; transfer any sleeves/spacers from the old damper to the new one
• Ensure the compressor sits level and that tubing is not strained before restoring power

Note: This part is "Cover Only". Does not include pans or glass. Order pans and glass separately by model.

This name plate is the exterior emblem that mounts to the appliance's front panel. It replaces a missing, cracked, or faded badge to restore a clean, factory look and cover the designated trim area.
