LG Refrigerator Not Cooling? Compressor Set TCA37071511 — Fix Cooling Failure Fast
If your LG refrigerator has stopped cooling entirely or is running warm despite the compressor attempting to start, a failed compressor assembly is the most common cause. In most LG French door and bottom-freezer refrigerators using R600 refrigerant, the compressor set is the heart of the sealed cooling system. When it fails, the fridge and freezer compartments warm up, the compressor may click on and off repeatedly, or it may run continuously without producing cold air. ⚡ One of the most common sealed-system failures in LG refrigerators built between 2015–2022. Part TCA37071511 is the genuine OEM R600 compressor set assembly that restores full cooling performance and replaces all superseded compressor variants in this family.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Refrigerator powers on — lights, display, and fans are working
- ✔ Evaporator fan is running (audible airflow in freezer section)
- ✔ Refrigerant charge confirmed OK or sealed system is being serviced
- ✔ ONLY problem is no cooling / warm fridge despite compressor attempting to run

🔧 Common Symptoms
- Refrigerator and freezer both warming up or not reaching set temperature
- Compressor clicks on and off rapidly (thermal overload tripping)
- Compressor runs continuously but produces no cold air
- Loud humming or buzzing from the compressor area at the back of the unit
✔ If these symptoms match, the compressor assembly is the most likely failed component in the sealed system.
✔ In most cases, replacing the TCA37071511 compressor set restores full refrigeration immediately after proper installation and refrigerant recharge.

Compressor replacement requires evacuating and recharging the sealed R600 refrigerant system — always replace the filter drier at the same time. A contaminated or moisture-saturated drier will cause the new compressor to fail prematurely. Have your certified technician source the correct drier for this system before beginning the repair.
⚙️ Installation
Skill Level: ADVANCED — 2–4 hours. Certified refrigeration technician required. Disconnect power and recover all refrigerant before opening the sealed system. Remove the old compressor, replace the filter drier, install TCA37071511, braze all connections, pressure-test, pull vacuum, and recharge with the correct R600 refrigerant weight as specified on the unit's data plate. Do not attempt without EPA/refrigerant handling certification.

💡 Pro Tip
Every time the sealed system is opened, moisture enters. The filter drier is a one-use component — once exposed to atmosphere, it must be replaced. Skipping this step is the #1 cause of repeat compressor failures within 6–12 months. Budget for the drier before quoting the job.
