Reply.The low suction pressures may cycle the compressor off prematurely. After a short period of time, the evaporator pressure will slowly rise from the small amounts of refrigerant in it and the heat load on it. This will cycle the compressor back on. This short cycling may keep occurring until the compressor overheats. In this video we go through the basics of checking a heat pump charge in heating. It can be tricky but its pretty simple if you do this..Title music:Music: B...
