The LG company manufactures a slew of window, wall and portable air conditioners under its own and other brand names, including Hampton Bay. Many of the problems that arise in LG air conditioners can exist in other brands as well. Although some of these problems a handy do-it-yourselfer can troubleshoot and fixother repairs may require qualified professionals.

After adding up the labor and parts costs, repairing a window unit may not be as economical as replacing it, especially if your unit is out of warranty or past its life expectancy, which is an average of 10 years. Some of the issues you may have with an LG air conditioner include:. A simple adjustment to the control panel settings can make a difference in the unit producing cold air.

Check the control panel settings to ensure they are set correctly. Verify the unit is set to Cooland then set the temperature to its lowest setting, which is 60 degrees Fahrenheit on most LG models equipped with a digital display.

Check the unit for cold air; it if is not blowing cold air it may require a refrigerant recharge by a certified professional. Improper installation can lead to a unit not working correctly. Verify the installation is correct and the unit is not obstructed. Check to ensure the airflow to the unit is not restricted. The unit must be installed with proper clearances on both sides and at the rear with no obstructions to impede airflow. Measure the distance from the window air conditioner to outside obstructions, such as a fence.

Confirm that the unit has at least a minimum of 20 inches between its exhaust and any obstructions. Check the unit for accumulated dirt or debris. The vents, air filter, evaporator coils, and condensing coils need to be kept clean through regular preventive maintenance to assure maximum cooling efficiency and longevity of the unit. The air filter should be checked and cleaned at least twice a month. The evaporator coils and condensing coils should be checked at least seasonally and when needed, carefully cleaned with a brush attachment on a vacuum cleaner.

For wall and window air conditioners, check the angle at which the unit is installed. Air conditioners that do not blow any more more than likely have a problem with the fan motor or circuit board that controls it.

After making all the adjustments, and a unit won't blow air at all, call for professional service. When the LG air conditioner won't power on, check various elements to ensure the unit has power. Plug a clock with a second hand into the wall outlet or use another electrical device to verify the outlet has power. Check for a tripped circuit breaker or blown fuse if the outlet doesn't work; reset or replace as needed. Press the Reset button on the power plug after verifying the outlet works, and then the Power button on the unit control panel.Page of 4 Go.
