LG Electronic Window Air Conditioner - Answered Questions & Fixed issues

At least 3. 1 on the inside unit fan, 1 on the outside unit fan and 1 on the compressor. The outside unit may have both in a single chassis.

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. West Palm Beach Air Conditioning

Still could be the fan capacitor. You cannot visually inspect a capacitor. It needs to be tested with a dvm. Beware capacitors store quite a bit of juice and although they probably won't cause permanent damage....the do hurt like hell when the discharge into you. You could try with the unit running spinning the fan manually BE CAREFUL. If it starts then the cap is probably bad. If not motor could be bad even if it spins ok.

randobrad had it exactly for me, the port to the outside was cleared but the one from front to back was clogged. Once I found the small port (using a wire hanger) it was easy.

remove filter and see if coil froze up. that will slow down air flow.

Try putting a hand on the grill while it's running to see if it dampens the noise.

These are quite easily damaged and sometimes just wear out. The cable from the motor can also be easily damaged. They are cheap and easy to replace. Just source a new one for that model online. When you receive it, turn off power to the system, take the front cover off, unscrew inside tray from cover box, slide tray out, remove the power box, get access to the motor and replace. Be sure to check which wires go where before removing and take photos or make accurate diagrams with color codes. Check that the control board functions normally before purchase though. A faulty board could cause this fault.

If it has humidity control and the cool is still on but set temp is higher than the room temp, the humidity control will override set temp. If it has no %rh control then it probably has a circuit board fault; micro relay is stuck closed and board needs to be replaced. Its probably the circuit board. On it, there is a little black box(s). About 1" X 1/2" in size. With long run times the small contacts inside will fuse/melt together.

Lg have 5uf capacitor installed in outdoor section along with comoressor unit. It bascially helps to rotate the condenser fan.

Yes. If it has a port installed from factory, it can be recharged. If it used R12, it can be purchased from Ebay. It the unit does not have a recharging port, you can also purchase that from Ebay. You need to know the size of tubing the port is going on. A pressure guage would also help troubleshooting.

Is the fan running?

First of all you need to check if your power supply to unit is correct (120v or 220v).

Hi,

The model number seems to be for a wall mount unit. here si the link for the manual:

I hope this helps.

I believe the "FP" probably stands for Freeze Protection and it's there to prevent your outside coil from freezing up and causing your head pressure to drop. To do this, it briefly has to reverse the cycle from heating to cooling. This is normal in a heat pump.

wait for it to bleed off then scrap it.usually not worth repair and recharge

Have a short in unit. Need to check continuity of each component to ground to determine where short is. Also make sure breaker is good.

Air sensor defective replace it.

If you have set the temp near to the room temp it will switch off and on. Set it to to 20 deg and watch. Even if it is not working properly then problem is with thermostat.S.S.MALICK

Turn off anti-gravity! AAARR AARR. Sorry don't know. murf427

Sounds like the drainage tube is stopped up or the canal. That should take care of your problem.
