Lennox RTU M# GCS16-090-200-2Y
#1 Compressor going straight into deep vacuum and high side sitting @ 100PSIG
#1 circuit holds 6 pds. Added 2 pds with no change in high side pressure
#1 circuit TXV frosted up as well as the distributor and cap tubes.
Compressor pulling low amps. Shutting down on thermal overload.
I'm thinking the compressor is not pumping but it sure is sucking
Soooooooooo is it the compressor or a restricted TXV ?
If restricted why not high head pressure ? Would it act as a pump down ( nothing in so nothing out ) Also how would a scroll compressor pump down but not pump ?
What a DAY
Guess I'm going back with both.
