Thank you. I replaced the cycle switch on the dryer but it didn't make a difference. It did not originally have a HP switch by the compressor but there is a port there. Just no wire or plug. The system was originally a 134a and I did the normal vacuum/oil fill/refrigerant fill per specs. I have run the system for a couple of hours today with no squeal or pressure over 300 sitting in my driveway LP in the 25 range. I just think that it should cycle like my accord... off and on. Is that what others have seen happen in their P30 systems?
Also, the cycle switch still has continuity even at the ~300 pressure range so not sure when that device will turn off...
