Yesterday our install crew put in a Trane HP Model# 2TWA0060A4000AB tied to a Trane A/H # TWE060A4000EL. They said it was cooling well when they left,
Today I get the call that it's short cycling and the occupant shut it off. Of course Im thinking its leaking but I get there and see equalized pressures of 150 PSI. I start it up and the head pressure never rises, but the suction drops to less than 10 and shuts off on LPS. This drop takes about 20 seconds. Service valves are open, I moved my gauges to the ports near the Rev Valve and get the same readings. There is nothing beween the comp dischage and the rev valve gauge port except for a muffler. I was thinking restriction at the txv but wouldnt that raise the discharge pressure as the suction drops? Again I get no pressure rise on the discharge. Its almost like the compressor is pulling in the gas but not discharging. Is this possible? I had to leave today to go to another appointment, but Im sure Ill be back tomarrow. Compressor pulls 5 amps (rated for 9.4 RLA) during its short run time ....ANY SUGGESTIONS?
