Does LG make good air conditioners?

Waldo (5/5/2020 5:13:25 PM):
Why does my LG air conditioner keep turning off?
Callum (5/5/2020 5:13:44 PM):

If your thermostat is near the air vents, it can think your surroundings are cool and shut down the AC. The air filter might have gone dirty. In fact, a dirty filter is one of the most common causes in regular AC problems. A dirty filter blocks the air flow and can make your AC turn off.

Vegas (5/5/2020 5:12:57 PM):

Daniel (5/5/2020 5:13:09 PM):

LG AC CH34 Error Code = ABNORMAL PRESSURE/OVERHEATING. This error displays if the SAFETY RELAY powers the unit down due to ABNORMAL PRESSUREbuilding within the sealed system. This feature is built into the unit to combat overheating issues.
