Question about LG Heating & Cooling

Air conditioner compressor keeps shutting down

I have a LG 1.5 tons Split A/C and have noticed that the compressor keeps shutting down when the temperature outside is above 40 celcius especially in the afternoon. For example, when i turn on the A/C and set the temp to 28 the A/C cools for about half hour then turns off without reaching the desired temp and then the compressor does not come back on for 30-45 mins. What is causing this is? is it a faulty compressor?? I have also got the capacitor replaced and it still did not solve the problem. I have another Haier 1 ton A/C and this works fine in the same conditions. Please help and thanks in advance.

This is due to thermal overload,Which can be caused by low oil in the compressor,the fan has stopped running on the unit outside,Dirty coils,or just a worn out compressor.Although this is thermal overload,It has nothing to do with outside temperature,But rather the internal temperature of the compressor itself.

    The best way is to have the unit totally evacuated and vacuumed,Then have new oil added and recharged with refrigerant.Since the Thermal overload can be caused by low oil,a partially restricted line,A loose connection in the wiring on the compressor,or the fan not working or working in the wrong direction(When the fan is working correctly,Air should be blowing out the top of the outside unit when the A/C is in cooling mode).



    If you can supply the results from previous test done,Such as the refrigerant charge pressure and at what ambient temperature,Head pressure reading(Pressure on the high side),fan direction,Etc.....

    I would be able to provide a more detailed solution.

Unfortunately, there is not a great deal of information about LG splits available, but is you are talking $12,000 to to repair, then it is much cheaper to replace since a two ton complete is less that half that amount.

Hi, I have to replace the capacitor (35 +2 microfarad) for my LG 1 ton, split Air Conditioner. The LG service guys had told that this model is nomore available with them. They tried some alternatives,...


Are you sure the capacitor is faulty? You can go up in U,F's but not down and if it is the capacitor it will work. For instance, you can use a 40x5. The larger number is to start the compressor ad the lower is for the outdoor fan motor. I know nothing of India, but if you have any appliance parts houses, they will have them, or can order one for you. A capacitor for that unit should be easy to find if you have parts places for appliance's there. Good Luck, and keep me posted. You can order on on the Internet from the States also. They are inexpensive, the shipping charges may cost the most. Have it checked out to make sure is is faulty. If it is swollen or deformed, or leaking oil, its bad. If not, take it to a repair place for appliance parts and check it for dead shorts or open windings..

5 ton split LG UNIT brand new about 1 year old.


Look up the term BLACK DEATH.


90-100 psi is very high on the low side.

Without spending too much time,I would pull a vacuum to -28 inch of mercury and let it sit over night.

Monitor the manifold garage for leak. (rise of inch of mercury)

My bet is the low quality LG compressor's worn out metal part is in the condenser.

Blockage will increase the low side PSI.

You can buy HVAC blow out can/chemical to clean line before you vac and fill the refrigerant.

Please let me know what's you founding is on reply.

My 1.5 ton,LG split AC shuts off rather


Hello
First the foam insulation is not just for looks,you will have some loss of cooling on the unit,the larger cooper line needs to be insulated,the small one does not.The large line is the suction line,the small one the liquid line.
Voltage,168 is low,sounds like a 208 volt unit or 220 volt.running at 168 or 198 ac volts is going to raise the amperage causing the compressor to run hot and work harder and soon burn up,And cause it to trip the breaker or shut itsself down on high heat.Your going to need to get that voltage fixed.I dont know why it needs a stabilizer if the unit was sized correctly it shouldnt need one.
Hope this helps.

The remote control operates intermittenly and there is no other way to shut down the AC


You have a ton and 1/2 split that's running all the time and problems with the remote?I am sure you have changed batteries if it has them. I would shut it off at the breaker until you can have the remote checked out or replaced. I know this would be a pain, to do, but you may have to until the remote is working right. Good Luck

Compressor keeps shutting off after 30mins or so


The system may be going into cool down mode or thermal over load if the temperature is 104 degrees fahrenheit or above since the compressor will shut down if the internal temperature reaches 165 degrees.This could also be from low oil in the compressor.
