Below are 7 LG inverter air conditioner issues for troubleshooting:

1. LG Inverter Air Conditioner Not Turning On

The LG inverter AC won’t turn on primarily due to a power issue. If something is preventing the unit from getting adequate power, the AC won’t start.

Such issues include the following:

  • Unplugged unit – Your LG inverter air conditioner won’t turn on unless it’s properly plugged into the wall socket and turned on. So, check that to ensure it’s the case. 

  • Tripped breaker – The breaker disrupts the air conditioner’s power supply when it flips off, even though it protects the AC from overheating.

  • Blown-up fuse – If the breaker doesn’t trip up during a power surge, the thermal fuse will blow, cutting off the AC’s supply. So, use a multimeter to examine the fuse’s continuity and replace it if it has no continuity.

  • Overloaded or faulty socket – If you overload the power socket with multiple appliances, the AC may not turn on. Likewise, the AC won’t turn on if the power socket is faulty (lacks continuity). Hence avoid overloading the socket and replace a defective one.

  • Faulty wiring – Here’s where you’ll need an electrician’s help. Have the expert scrutinize the wiring to identify signs of faults and fix them.  

  • Faulty control panel – Lastly, if the control panel won’t power up, the AC won’t turn on. Try powering the control panel on, but if it doesn’t power on, request an expert service.

2. LG Inverter Air Conditioner Not Heating

Usually, the LG inverter AC goes through a short pre-heat period when you turn the heat on. So it doesn’t heat immediately. But once a few minutes pass and the AC doesn’t blow any cold air, check for the following:

  • Wrong Setting – The LG inverter AC will only heat when it’s on heat mode or the indoor unit temperature is 18 – 300C. If that’s not the case, ensure you adjust the unit’s temperature accordingly. 

  • Faulty heater – If the heater is defective, it won’t produce any heat, so your AC won’t blow hot air. You can try making your hand to the air vent or intake grille to see if you’ll feel warm. If not, the heater is faulty and so replace it.

  • Frozen unit – This is likely to be the case during the winter. The AC may take time to pre-heat, but you can always try to thaw the ice first.

  • Power disruption – the AC won’t heat if the breaker trips or the fuse blows up. So, check them and act according to the tips I shared earlier about the same. 

  • Clogged filter – Since a clogged filter obstructs the airflow, hot air won’t blow or circulate within your space. That’s why it’s advisable to clean the air filter every two weeks.

  • Wrong size – If the air conditioner is too tiny or big for your space, it won’t adequately heat or may fail 100%. That’s why you should consider your AC’s BTU rating and ensure it matches your room size, and below is a table to guide you.

AC’s BTU RatingRoom Size (sq.ft)
7,000 – 8,000 BTU200 sq.ft
10,000 BTU 300 sq.ft
11,000 BTU400 sq.ft
12,000 BTU450 sq.ft
13,000 BTU500 sq.ft
14,000 BTU600 sq.ft

3. LG Inverter Air Conditioner Not Cooling

Several issues could prevent the Inverter AC from adequately cooling your space or cooling at all. The problems, in this case, include the following:

  • Wrong setting – The inverter Ac will only cool on Cool Mode or when the indoor unit’s temperature is 18 – 320C. So, ensure that’s the case; if it’s not, adjust the temperature correctly.

  • Restricted airflow – The AC won’t cool if the air filter, condenser coils, and air inlet are dirt-clogged or there’s no sufficient clearance (at least 20 inches) around it. So, you’ll need to clean the air filter, coil, and air inlet if dirt-clogged and create a 20-inch plus clearance around it, 

  • Indoor heat source – If there’s a heat source indoors (an oven, burner, running computer), it could interfere with the AC’s cooling if the two or near. If so, you need to distance them. 

  • Wrong mode – The air conditioner, as I mentioned, will only cool properly when in Cool Mode. Modes like Energy-Saver, Dehumidification, Air Purification, or AI (Artificial Intelligence) prevent cooling. If so, revert to Cool Mode.

  • Low refrigerant – Once the refrigerant level drops, the air conditioner cannot absorb the room’s excess heat, thus being unable to cool. Consider requesting a service inspection of the refrigerant if the AC won’t cool up to this point.

  • Wrong AC size – Lastly, the reason why your AC won’t cool might be because it’s the wrong size. So, refer to the earlier table to see if that’s the case and replace the AC. 

4. LG Dual Inverter Air Conditioner WiFi Not Working

The connection between your router and AC may fail for different reasons, such as:

  • Poor signal – Different issues could weaken the WiFi signal and prevent the AC from connecting to WiFi. It could be that the distance between the router and AC is more than 30ft which shouldn’t be the case. It could also be that the router needs a quick reset or a dense wall blocking off the signal, which you should avoid

  • Weak password – If the password is too weak., someone might be using the WiFi, causing its signal to weaken. So, if that’s the case, you must set up a much stronger password.

  • Wrong password – You might also be inputting the incorrect password, and that’s why the AC won’t connect to WiFi. Thus, it helps double-check the password and ensure you use the correct case. 

  • The router could be off – You could also have forgotten an important detail, and that’s to turn on the router. So, double-check it, too, and turn it on if it’s off.

5. LG Inverter Air Conditioner Leaking Water

You wouldn’t want your Inverter AC to leak, but it could happen due to these reasons:

  • Tilted installation – Ideally, the inverter AC should only be sloped ¼ – ½ inch outside. If not, it may start leaking. So, check the tilting and adjust the AC’s slanting angle correctly. 

  • Clogged filter – A clogged air filter will prevent drainage and will instead cause a backflow. So, inspect the air filter for dirt clogging and clean it accordingly.

  • Frost build-up – If frost builds up, especially in the winter, it will melt and drip. You must thaw the ice before turning on the AC to prevent that. 

  • Loose drain hose or drain cap – The AC may also leak water if the drain hose or the drain pan is loose. You need to check them and secure them firmly. 

6. LG Inverter Air Conditioner Power Light Flashing

Usually, the Inverter AC flashes the power light when something is wrong. Sometimes the light may blink severally or be accompanied by an error code.

Generally, here are the reasons the power light will flash:

  • Communication fault – If there’s a communication failure between the indoor and outdoor units, the inverter AC will flash the power light five times. If so, consider resetting the AC to see if the flashing stops. 

  • Clogged condensate line – The Ac may also flash the power light if the condensate line is dirt clogged. So, you’ll need to check it and clean it. 

  • Power failure – During a power failure, the AC won’t just blink the power light but will also display the error code CH00. If so, try resetting the AC but if the flashing doesn’t stop, call an electrician. 

7. LG Inverter Air Conditioner Remote Not Working

Lastly, here are the issues that could prevent the AC remote control from working:

  • Long range (over 10ft) – If you hold the remote control more than 10ft away from the inverter AC, it won’t work. You should hold it close by and away from dense barriers or walls. 

  • Wrongly placed or exhausted batteries – Check the batteries to ensure they are correctly placed. If not, remove them and put them the right way. If the AC still doesn’t work, replace the remote’s batteries, as they could be exhausted.

  • Faulty remote – If the remote sensor light/LED or buttons are damaged, it won’t work. You’ll need to replace it if that’s the case. 

  • Bad control board – Consider the possibility that the fault might not be the remote but the AC’s control board. Have an expert check it and replace it if it’s faulty.
