Posting this for Jeff, and not to dog pile on the fix for Coach 1482.

Specific to the issue Jeff mentioned in the other post about potentially adding more cooling to the Condenser fan to reduce head pressure and increase cooling. That may be the solution indeed.

But…………..there could be other things at play. High head pressure / low suction is quite often a partially plugged TXV. Second thing is it is EASY to get too much refrigerant in these systems IF you charge them like you would a car. I usually charged to get low side to 20 to 22 psi in 85 degree weather. You would normally see much higher low side pressures in a car but the long lines in the coach alter the usual readings. I would see about 225 high side and 22 low side when it was right. If I went much higher on the low side, the high side would start climbing and the cooling would decrease. Yeah, I know, it’s counterintuitive. Too much gas results in higher cooling temps, too little gas results in lower temps.
