LG Heat cool Window Air Conditioner - Answered Questions & Fixed issues

Reset the external breaker for the unit it should be next to the unit or in your power box.

You need to have an AC tech come out and do some preliminary testing on this.

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. If you have any other Air Conditioning Repair Questions don't be afraid to let us know.

See if you can reposition the thermister on the facing of the evaporator coils. That could be it or the thermister might be bad. They don't use copper/mercury sensing bulbs these days. They use these cheap thermisters. If you need further help, reach me via phone at https://www.6ya.com/expert/dan_73bbd84fe1d95b61

Does not sound right to me.My guess after doing what every he was doing he probably installed a start capacitor or repaired a burnt wrie, got the compressor running and charged for a lot of guess work. Just guessing.

If the drain is clogged or the ac is not slightly tilted towards the outside, the condensed water will leak inside instead of outside where it belongs.

Check the nameplate for input voltage

Check to see if there's power to the reversing valve, if there is, try tapping it slightly with something kind of soft. You should give the reversing valve solenoid a continuity check with an ohmmeter to see if it's open or shorted.

If this is a window or wall mounted single piece unit, open it and check for a loose compressor or fan mount.

how do I set it to heat up the room?

Check the controls, this unit most likely a reverse cycle air conditioner. It can be set to cooling or to heating. The conpressor is reversed to heat or running normally to cool.If it is not then the compressor is not working and it is just blowing room temperature air.

bad compressor or capacitor

Hello, Here is a trouble shooting guide for you and some details of how to fix it based on your symptoms. Here is a link to go to and make sure you jump around the site, it will tell you the fix based on your problem off the trouble shooting table. Link is below , copy and paste in browser. If this helped you, please rate it and some kind words are nice. Thanks Mike http://home.howstuffworks.com/home-improvement/heating-and-cooling/how-to-repair-room-air-conditioners1.htm

Unplug the a/c and check the control panel of your a/c. Unscrew the control panel to expose the wires and terminal lugs.Check for lose wires or terminal lugs or defects from the compressor capacitor. If all are OK try adjusting the thermostat switch to make the contacts work. If the capacitor is damage replace it and replace any damage terminal lug. If the compressor still does not work, check the overload and the compressor resistance. If overload is open, replace it and check compressor amperage. If the compressor amperage is high, you have to replace the compressor, vacuum, and recharge freon.

Unfortunately, 7000 Btu's will not cool 1180 sq ft. At best, it's rated for 400 sq ft, as it's only rated as a "Room Air Conditioner". To cool 1180 square feet, you'll need at least 30,000 Btu's (like in Central Air Conditioning) or 4 more window units spread out throughout the condo. It takes more Btu's to cool, than it does to heat.

I really sorry. I wish I had better news for you. Thanks for choosing FixYa.

check main power breaker, and reset breaker on unit, otherwise lightning storm would have nothing to do with units problem other then power surge, which would trip a breaker. Hope this helps, Thanks Mike

Unplug the unit. You will need to gain access to the blower motor inside the unit. Try and turn this motor by hand. If it is frozen, lubricate it. If it is not frozen, you either have a burned out motor, or you have an electrical failure.

Most motor failures are due to lubrication problems. It could be lack of lubrication for whatever reason. It could be contamination of the bearing system. If you don't grease a motor, sooner or later it's going to fail. If you lose grease in the bearing during cleaning, a failure is imminent. High motor and bearing temperatures also will tend to dry up the grease over time.

If you are not familiar with working on A/C units, motors, etc., I would recommend having a service professional repair the unit, or you can purchase a replacement. I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

Hello, the evap coil will freeze from either low airflow or low charge. I would clean the coils, check air filter and replace or clean if dirty. If you have a thermometer measure the air entering the ac and the air leaving the ac, the differance should be 15-20 degrees, measure this after cleaning the coils. If it still is below 15 degrees the unit is underchraged.

There may be something in the fan or could have the bearings worn in the motor. If you're careful you can turn the unit to the off position, take the plastic front off, reach in thru where the air blows out and try to give the fan blower a spin and see if it is free. If it isn't, try to find whats holding it. If it is, the bearings are worn and you'll have to have a new motor.
