Hi All
I have this small LG 12000 BTU window unit which totally stopped working. Power from wall socket is good. Power plug and wires good.
Opened the unit up and saw the wires going into the 'Common' pin of the 2-in-1 capacitor, fried. I repaired all the wires/pins and also checked the dual capacitor for (Herm)30uF and (Fan)5uF. Both show me what they supposed to show. Fixed up everything and bingo, the unit ran. The compressor kicked in but stopped about 2 seconds later!!. after 60 seconds, it ran again and 2 secs later it stopped. that is how it was all the way.
From my findings, the high temp switch located on top of the compressor could have opened the supply to the compressor since the compressor gets too hot. So what could be the problem?
Capacitor capacitance measured, ok. But one thing i dont understand is, this compressor only has a run (herm) capacitor (2-in-1 capacitor with the other lead for fan). Why does it not require a start capacitor?
Any kind of advice is much appreciated
