Question about LG Heating & Cooling
It sounds like the head pressure is to high. This is sometimes do to overcharging. The hissing noise that you hear is the liquid refrigerant dumping into the suction side. This is what a compressor does when the Head pressure is way too high. The fact that it is tripping the breaker may be to a broken suction valve in the compressor. I think it might be time for a new unit.
