does this sound correct? 75degf ambient and head master is bypassing hot gas causing high head pressure. am i thinking correct when i say it is doing this because the headmaster is backing liquid into the condensor and putting hot gas into the reciever but the hot gas is not condensing because of the high ambient, filling the reciever with gas which takes up more volume than liquid. so the unit does not have to be overcharged to cause the high pressure when the headmaster is bad. this would be a sporlan oroa-5-180 with r-22.
