LG air conditioners troubleshooting. LG manufacturing company manufactures a slew of different kinds of AC units for window, wall, and portable use under their own name and various brand names.
Things that go wrong with ACs, in general, can also exist with LG ones. Although DIY repair is sometimes possible for these problems, many require the help of professionals to fix them.
This can get expensive, so it’s important to decide between repairing your unit or if it’s time to buy a new one.

LG air conditioners troubleshooting. LG manufactures a slew of different models of air conditioners under its own name, as well as under the names of other companies like Hampton Bay.
Although many of the problems that arise in LG air conditioners can exist in other brands as well, depending on your region or which particular model needs repair, some issues may be less common.
The LG air conditioner won’t cool
The air conditioner cannot function if the air filter is clogged. This significantly reduces cooling efficiency. Additionally, a dirty air filter will cause the evaporator coils to frost over and require cleaning or replacement.
Try cleaning your air filter to get rid of debris. If it cannot be cleaned, then you will have to order a new one. Assuming your compressor is in good working condition, check other common problems first before replacing it, which should usually only be done by a licensed technician.
Have problems turning off
Heat and air conditioning systems are controlled by thermostats that supply voltage to fan motors.
As the temperature inside the duct increases or decreases, the thermostat establishes a connection between the two wires, which activates the compressor.
Your thermostat may keep running all day long if it has shorted out, causing your air conditioner to work harder than it needs to.
Take off your old thermostat and check with a multimeter both pairs of wires it was using for testing to see if it has a faulty thermostat that is being too literal with its electrical current.
if there’s continuity on all three of them, the wiring is damaged in which case you should replace your thermostat with one that’s not as stubborn about keeping up its excellent work.
Compressor won’t work
The most common cause of a compressor overload protector tripping is a defective motor. Even if the compressor motor is defective, it’s usually not the only component that has suffered damage.
If the motor overload protector trips, be sure to check other components—particularly the compressor capacitor and overload protector. If these parts are defective, they should be replaced by qualified technicians.
The LG air conditioner fan does not work
The dual shaft fan motor might be faulty. The dual shaft fan motor is (simply put) broken down into two smaller motors, each having a different job to do.
On one side, the fan draws air in over the condensing coil to dissipate heat built up inside the system. On the other side of the device, the fan draws air past the evaporating coil so that heat will be extracted from your home.
These two parts are regulated by small bearings that can loosen or bind after some time, making them unable to accomplish their specific tasks.
To determine if this part is defective, wiggle both rods/shafts and ensure they move freely or not at all as needed. If either rod cannot perform its designated task adequately, then you will need to replace this dual motor.
Air conditioner remote control not working
First, try replacing the batteries in the remote control. If installing fresh batteries does not solve the problem and you still can operate your remote-controlled air conditioner manually,
there is a chance that your remote control may be malfunctioning. If you think that’s the case, replace it.
Noisy or loud air conditioner
Compressors start to make loud noises sometimes, and it’s not necessary to replace the whole thing.
A good rule of thumb is to ignore them unless they make an unusual amount of noise or if you don’t want to take a chance on them making a lot of noise at a big job in the future.
The fan motor is often noisy, too if that’s the case, then get a new one for sure!
When working in hot, humid conditions, noise from the air conditioner is unavoidable.
Air conditioning capacity will decline if the outdoor coil or indoor evaporator coil becomes excessively dirty, and clogged with dust or leaves and debris.
Install a clean filter, which gives you improved comfort for several years.
