Troubleshooting an LG Air Conditioning Unit

LG ducted air conditioning systems are quiet, reliable and a well-regarded industry standard. However, like most equipment these units can occasionally fail, this may be due to a small issue that has arisen because of infrequent servicing. In many cases, it is a good idea to seek out a local professional to fix the problem, but that may not be necessary in every case. In fact, some troubleshooting can be carried out by people with only a little DIY experience. Of course, anyone undertaking this kind of work should follow basic safety procedures and seek professional help if they are unsure of anything.

Locate the Manual

Keeping the LG air conditioning manual safe is crucial as it contains a great deal of useful information. Many common faults are discussed in the manual with easy solutions that can solve many minor problems. Another great resource is the LG website that has pdf’s of all their manuals available for download if the owner’s copy has been misplaced.

The Unit is Not Cooling

When troubleshooting LG air conditioning, Perth residents may find that although the unit appears to be working, it isn’t cooling the air. This could simply be that an adjustment is necessary on the control panel. Check the control panel settings and make sure that the unit is set to cool. Try lowering the temperature to the lowest setting possible which is usually 60 degrees Fahrenheit on most LG cooling units. Then try adjusting the fan speed and crank it up to its maximum setting. The unit should now be blowing cold air at a high speed. If this hasn’t corrected the problem, the unit may require a refrigerant recharge that must be carried out by a professional.

Solving Power Issues

If the air conditioner will not power on it is necessary to check to ensure that the unit is receiving power. If the indicator light located on the power plug is not lit, check the outlet with a different electrical device to see if it is working. It may be that a fuse has blown or the circuit breaker has been tripped, if this is the case, then you will need to replace the fuse and reset the breaker. Once these tasks have been carried out press the reset button and then the power button on the control panel. If the unit is still not receiving power now, it’s time to call on a certified professional.

Check For Obstructions

It may be the case that the air conditioning unit has been installed incorrectly. Alternatively the circumstances surrounding the system may have changed. This could manifest in the form of overgrown foliage in the garden or other debris that is obstructing the cooling unit. If the unit has been obstructed, the reduced airflow will cause the system to work less efficiently. Outside obstructions such as fences should be at least 51 cm from the exhaust. There should be adequate clearance around the unit and any blockage to air intakes such as window or furniture treatments should be removed.
