The ACs seem to be a total waste of money if they cannot cool when the weather is most hot.. money down the drain
Future buyers, please beware of LG and don't waste your money on ACs which don't cool when the ambient is 45 Degrees. |
There are a lot of reasons for this
. Direct sunlight falling on the ODU, hence AC internals are over heating
. Bad installation resulting in poor ventilation of internal components.
. Choked condenser.
Call LG service and register the complaint. When the technician comes ask him what the error code means.
Similar problems were faced by my BIL and other residents in Dwarka. Most of the AC's would stop in extreme heat, but if you switch them off and wait for the machine to cool, they start running. Here is what I think is happening :-
Each compressor has a Thermal Cut Out to trip the compressor in case excessive current is drawn. The cutout just heats up an element with excess current and then trips. So if the internals heat up a lot, the compressor will trip. Bad ventilation or choked condenser are usual culprits.
Your only recourse is to discuss the problem with the technician and get his opinion and solutions.
One trick used thirty years ago in Delhi is to drip water onto the condenser from a tank placed on a window AC (can be done with a split also). That results in better thermal efficiency hence the AC cools better and as the compressor is strained less it also remain cooler. |
