LG art cool LA120HP thru wall air conditioner. when I turn on the unit it starts however as soon as it kicks on, I think the compresser, the unit beeps and turns off. why and what do I do
Use a clamp on ammeter to check the LRA (locked rotor amperage) at the moment the compressor is energized. It should not exceed the rated LRA printed on the data plate. If it does then ohm the compressor for a ground or short between windings
