Early Warning Sign: Ice Maker Stops Working
In this repair case, the homeowner noticed their ice maker stopped functioning. While the fridge still seemed operational, cooling efficiency had dropped. Within days, food in the fresh food section began to spoil. The first component to stop working in many LG fridges with compressor issues is the ice maker. If that happens, it’s time to act quickly.

Fast Response in Houston ZIP 77043
Our team responded within two hours of the service request. From diagnosis to full repair, it took just 3–4 hours. The job was completed same-day thanks to our technician having the correct compressor in stock—a rare but valuable advantage of choosing an experienced local company.
Diagnosing the Issue: Compressor Underperformance
The LG FLD090LANA linear compressor was still running but not providing adequate cooling. Gauge readings confirmed low discharge pressure and high suction pressure, which indicated internal failure. Although it hadn’t stopped completely, the compressor was no longer moving refrigerant efficiently.
The ice maker failure and rising compartment temperatures were strong indicators of compressor issues. These symptoms align with common signs of LG fridge not cooling.
Compressor Replacement: TCA36491304
The faulty compressor was replaced with the factory-authorized LG part TCA36491304. This kit includes the compressor, installation hardware, and drier. It’s fully compatible with R134a systems and the inverter board used in this model.

Maintenance Tips: Pet Owners, Take Note
During disassembly, the condenser coils were found to be completely clogged with dust and pet hair. The customer owned a large dog with thick fur. Overheating of the sealed system can accelerate compressor wear.
We strongly recommend a professional refrigerator maintenance service once a year—especially for pet owners or homes with higher dust levels.
How to Prevent This in the Future
- Vacuum the condenser coils annually
- Check for warm air behind the fridge
- Listen for odd compressor noises
- Monitor ice production – it’s the first to fail!
When to Call a Technician
If your LG refrigerator is not cooling and you’re in Houston, don’t wait:
- Minimize door openings
- Transfer perishables to a cooler
- Call immediately if temperature exceeds 45°F
Delaying service can lead to spoiled food, damaged liner walls, and more expensive repairs.
