Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.These factors will put a very light load on the compressor and cause the amp draw to be low. Short Cycling on the Low-pressure Control — The compressor may short cycle on the low-pressure control, depending on how severe the restriction in the TXV is. The low suction pressures may cycle the compressor off prematurely.High superheat and low subcool is a indicator of a low charge. Overall low head pressure on both sides of the gauges is also a good indicator.
