LG Refrigerator Not Cooling? Compressor TCA38151706 / FLS075LANA – Sealed-System Replacement
May restore cooling when sealed-system diagnosis confirms compressor failure. No-cooling symptoms can also result from refrigerant leaks, restrictions, control-board faults, fans, sensors or other sealed-system components. In select LG French-door and side-by-side refrigerators, the TCA38151706 is the genuine LG sealed-system compressor set assembly using compressor model FLS075LANA. When the compressor fails, the refrigerator may run continuously without cooling, produce no cold air, or shut down on thermal protection. ⚡ Compressor replacement requires refrigerant recovery, brazing, evacuation, charging and qualified sealed-system service. This is not a DIY repair. ⚠️ LG software update kit CJT30000002 is required before commissioning this replacement compressor. Order separately. Follow LG service instructions and warranty requirements. Confirm the complete refrigerator model, refrigerant type and data plate before ordering or installation.
❓ Is This the Right Part?
This is the correct replacement if ALL of the following are true:
- ✔ QUALIFIER 1 — sealed-system diagnosis has confirmed compressor failure (not a fan, sensor, control board or refrigerant leak)
- ✔ QUALIFIER 2 — refrigerator model, refrigerant type and data plate have been verified against TCA38151706 specifications
- ✔ QUALIFIER 3 — qualified sealed-system technician is performing the repair
- ✔ Software update kit CJT30000002 has been sourced and will be applied before commissioning

🔧 Common Symptoms of Compressor Failure
- Refrigerator runs continuously but does not cool — both fresh food and freezer sections warm
- Compressor starts briefly then shuts off on thermal overload protection
- Compressor does not start — no vibration or hum from the compressor area
- Sealed-system diagnosis confirms compressor failure after ruling out fans, sensors, control board and refrigerant charge
✔ If sealed-system diagnosis confirms compressor failure, TCA38151706 is the correct OEM replacement assembly.

💡 Pro Tip
Compressor failure is one of several causes of no-cooling in LG refrigerators. Before ordering, confirm the inverter board, fans, thermistors and refrigerant charge have been evaluated using LG’s model-specific service procedure. A misdiagnosed compressor replacement is an expensive and time-consuming mistake. If you need help confirming the diagnosis, contact us with your model number and symptom description.
