Here we go going to be hard to explainn entirly on here but I'll try I have a YCH180B3L0FA 2003 year the compressor went down short to ground on 2 legs replaced compressor found head pressure border line high 250psi and suction border line low 55-60 psi it was 87degrees out side we have replaced orfices with a txv upgrade no change blew out coils all look clean cleaned indoor and ooutdoor coils replaced air filters replaced blower belt and weighed the charge in no change now for the tech numbers subcool 25degrees superheat 10 degrees 18.5 delta t at the unit SA 49.6 RA 68 outdoor temp 87 has 98 degree temp diff. in liquid line going into condenser and coming out and the air across the condenser wsa 85 in and 105 out. now that its gotten hot we had to disable 2nd stage because its going out on hea pressure. Have tried to adjust subcool will not come below 23 degrees and that was with 9lbs removed only hold just over 13Lbs. Both condenser fans are on. All the tubes in both coils are open blew them out with nitrogen and pulled a vac. to 430 microns put a sight glass in the line before the TXV and dont see any liquid going threw it which is odd. Need some help don't really know what else to check seems like its over charged but again took over half the charge out did not help much.
