Here we will discuss some common issues and solutions for the LG portable air conditioner compressor not working.

Overload issue

An overload device acts as an additional safety measure to prevent a motor from overloading.

Overloads can wear out over time and are found inside of the motor housing and wired to the compressor terminal block.

If an overload is no longer creating a circuit with the compressor terminals, then it will be necessary to replace it.

Replace Main Control Board

When the problem persists after checking out more commonly defective components in your device, it’s possible that one of the main control boards is faulty.

Before replacing the board, first, check the feeds and speeds of fans and blowers to ensure that they are working properly. This may be a sign that the blower motor or inverter board may need replacing instead if any of these things are malfunctioning.

 Defective Relay Board

Some of the main components that control how the air conditioner works include the power relay, compressor, and overload protector.

If these are not functioning properly, you will not be able to feel any sort of breeze or cooling coming from your AC no matter how many times you might have heard someone mention that it’s working.

That is why it would be really important to look into other parts that might be causing some sort of issue with the relays themselves.

 Faulty Thermistor

The thermistor is a sensor-equipped to detect the temperature of the air. If it does not have continuity, it will stop the compressor from running.

In case of a faulty thermistor, use a multimeter to test for continuity; if not found, replace it.

A capacitor is burned out

If your refrigerator compressor doesn’t run, one of the first things to inspect is the condenser. Using a multimeter, test the condenser for continuity.

If it’s not conductive, your condenser has failed and needs to be replaced.

Check Temperature Control Board

The temperature control board is responsible for sending power to the compressor as well as the fan.

If you are experiencing problems with your HVAC unit and have replaced the temperature control board and continue experiencing trouble.

Check that you have not missed any other commonly defective parts, including the compressor itself or the capacitor.

Temperature Control Thermostat Fault

Electrical contacts inside the temperature control thermostat wear out over time. This is normal, and the thermostat will frequently switch on the fan motor but not the compressor motor.

Damage Thermostat

The temperature in your home is monitored by the thermostat. As your air conditioning system’s fan and compressor are powered, it activates a switch when the temperature reaches a set point.

If the thermostat is defective and either stops providing power or supplies it inconsistently, you may notice that your air conditioner does not consistently crank up as high as it should.

When you’re at work or when you go out for the evening. To fix this problem, replace the defective thermostat with a new one.

A problem with Compressor

The compressor itself might be defective, especially if the motor continues to run and won’t shut off.

However, this is not usually the case (more commonly it is a problem with the overload protector or capacitor).

Before replacing the compressor, be sure to check these other things as they could indicate more severe problems.

Selector switch might be at fault

The compressor turns on and off when the air-conditioning system selector switch is turned to different settings.

If the compressor runs, but the air-conditioning system doesn’t cool, check that power is reaching the electrical plug.

Then check the capacitor (C1), overload (L2), and all wiring and connections to them (L1).

If these things operate as they should, test cycling of the compressor terminal switches (S1 & S2) may indicate a faulty selector switch circuit board.
