LG Refrigerator Compressor,Set Assembly

The LG Refrigerator Compressor Assembly (Part Number: TCA38311805) is an authentic original equipment manufacturer (OEM) replacement variable-speed Smart Inverter compressor set designed for select LG frost-free double-door refrigerators (including models in the GL-T342TPZY and GL-N342SDSY series). Positioned at the rear base of the refrigerator in the machine compartment, this sealed compressor pressurizes and circulates eco-friendly refrigerant through the sealed cooling system. Designed with smart inverter technology, it adjusts motor speed based on internal cooling demands, reducing operational noise and minimizing overall energy consumption.

Key Features

• Variable-Speed Smart Inverter Technology: Dynamically adjusts motor speed according to ambient temperature and door usage to maximize energy savings and maintain precise compartment temperatures.

• Genuine OEM Precision Engineering: Factory-manufactured directly by LG to ensure precise mechanical mount alignment, correct suction/discharge tube dimensions, and seamless inverter board communication.

• Low-Noise & High-Efficiency Design: Internal mechanical dampening minimizes motor hum and vibration during variable-speed operation.

Benefits

• Resolves warm cabinet conditions, complete loss of cooling, or compressor motor failure.

• Restores energy-efficient operation and low noise levels across cooling cycles.

• Direct OEM replacement ensures factory-certified electrical safety and long-term durability.

Applications

Designed specifically for select LG frost-free double-door refrigerators requiring compressor part number TCA38311805.

What's Included

• 1 x Genuine LG Refrigerator Smart Inverter Compressor Assembly (TCA38311805)

Usage Instructions

1. DANGER: Unplug the refrigerator from the main electrical outlet and ensure the sealed system is completely discharged of refrigerant.

2. Access the lower rear machine compartment panel at the back of the appliance.

3. Using specialized HVAC tools, recover refrigerant safely according to environmental guidelines.

4. Unplug the electrical wiring harness connector and ground lead from the compressor header.

5. Un-braze (or cut) the suction, discharge, and process lines attached to the old compressor.

6. Unclip the base mounting stoppers and lift the old compressor off its rubber grommets.

7. Install the new LG TCA38311805 compressor onto the rubber grommets, braze the copper lines using proper nitrogen purging techniques, replace the filter drier, evacuate the system using a vacuum pump, recharge with the specified refrigerant weight, reattach wiring connectors, and test operation.

Safety Instructions

• SEALED SYSTEM WARNING: Installation requires certified refrigeration/HVAC repair equipment, silver brazing, vacuum evacuation, and proper refrigerant handling. This repair should be performed by a qualified appliance technician.

• Always disconnect main AC power before opening machine compartments or touching electrical components.

Care Instructions

• Maintain clean air circulation around the lower rear machine compartment panel by vacuuming dust and lint off surrounding condenser coils periodically.
