Common Causes
LG portable air conditioners sometimes stop cooling properly. Several common causes affect their performance. These issues often have simple fixes. Checking these can save time and money. Understanding the causes helps maintain comfort and efficiency.
Dirty Air Filter
The air filter traps dust and debris. When it gets dirty, airflow reduces significantly. Poor airflow limits the cooling ability of the unit. Clean or replace the filter regularly. This simple step improves cooling and air quality.
Blocked Exhaust Hose
The exhaust hose removes hot air from the room. If it is blocked or kinked, hot air stays inside. This stops the unit from cooling effectively. Ensure the hose is straight and fully connected. Clear any obstructions to restore proper airflow.
Incorrect Unit Size
Choosing the wrong unit size affects cooling power. A small unit cannot cool a large room well. The air conditioner will run longer without cooling enough. Select a unit that matches your room size for best results. Check the manufacturer’s guidelines to find the right size.
Full Water Tank
Portable air conditioners collect moisture in a water tank. If the tank is full, the unit may stop cooling. Some models automatically shut off to prevent leaks. Empty the water tank regularly to keep cooling uninterrupted. This simple maintenance keeps the unit working efficiently.

Basic Checks
Basic checks help identify simple reasons why your LG portable air conditioner is not cooling. These steps save time and effort before calling for repairs.
Start with the easiest fixes. Often, the problem lies in settings or maintenance. Follow these checks carefully.
Cool Mode And Thermostat
Ensure the unit is set to “cool” mode. The thermostat should be lower than the room temperature. This triggers the cooling cycle. Wait a few minutes after turning it on for it to start cooling.
Air Filter Cleaning
A dirty air filter blocks airflow. Remove the filter and check for dust or debris. Clean it using water or replace it if it is very dirty. Clean filters improve cooling performance.
Exhaust Hose Inspection
Check the exhaust hose for bends or blockages. The hose must be straight and fully connected to a window or door. A blocked hose traps hot air, reducing cooling.
Emptying Water Tank
The water tank collects condensation. When full, the unit may stop cooling or turn off. Empty the tank regularly to keep your air conditioner working well.
Advanced Issues
When your LG portable air conditioner stops cooling, simple fixes can help. These quick fixes often solve common issues without needing a technician. Try these steps to restore cool air fast and easily.
Defrosting Coils
Ice buildup on coils blocks cold air. Turn off the unit and unplug it. Let the ice melt completely. This may take a few hours. After defrosting, clean the coils gently. Restart the air conditioner and check for better cooling.
Resetting The Unit
Resetting the air conditioner can clear errors. Switch off the unit and unplug it from power. Wait for about five minutes. Plug it back in and turn it on. This can refresh the system and fix minor glitches.
Repositioning Exhaust Hose
The exhaust hose removes hot air outside. If it is bent or blocked, cooling stops. Straighten the hose and remove any kinks. Ensure it vents properly through a window or door. This helps the unit cool the room efficiently.
