Question about LG Refrigerators
I have an LG LST243C-2 air conditioner in my unit. The previous owner did not leave a manual. They air conditioner appears to be working but does not cool. I would like to try cleaning the compressor, but do not have the instructions. Can you provide these or suggest other reasons why it may no longer be cooling even though it appears to be in working order otherwise. Thanks.
First thing to check is look and see if there is thick frost build up on the back lower panel inside the freezer? If not there must be a problem in the damper (vent). Let me know what you find so I can help.

If the fan inside the freezer is running and the compressor behind the fridge is running and is hot to touch, you have a gas problem or the compressor is inefficient. This can only be confirmed by connecting refrigeration gauges to the gas system and should only be performed by a fridge tech.

It could be as simple as being low on refrigerant. Depends on how expensive the unit is if its worth recharging and how big the unit is. Some small units will need to have a recharge point fitted which cost more of course.

Fuse 9, 50A under hood, Fuse 5 15A Instrument panel. If they're ok, make sure the compressor clutch can be turned by hand (engine off, obviously). If not replace the compressor. Most common problem is the cycle switch. That should be the electrical connector on top of the accumulator. Just jump that by backprobing the connector on both sides with a pinand connect them, with the car on and a/c on if the compressor clutch engages, replace the switch. If it doesn't, try wiggling wire harness and watch it, if it engages, find a broken wire and repair it.
