I have a package heat pump that is not cooling in the cooling cycle. I have a low amp draw, like 9.3 amps. I think my rating is 23.0 amps, and my gauge pressure is 150# suction, and #150 head while the system is running. It is a TXV system, with no reciever or accumulator. The suction and head seem to be equalized with the system running. The compressor cuts out on internal O/L before it shuts off. Could it be an issue of overcharge? or could it be a compressor with weak valves? I suspect the compressor has weak valves. Has anybody else seen this sort of thing?
