Probed with the temp sensor today, no cold areas or anything that seemed odd. All the high side hoses were too hot to touch, and the low side was mediocre cold at best...
Condenser inlet and outlet temps show a 80F drop, so the fans are shedding heat fine and its not a blockage in the condenser...the pressure is just off the charts.
Here's proof the pressures keep going up and up. I added about another 1/2 a can in. I stopped because with whatever is going on, is not following your theory.
This is at 1500rpm with both aux fans going full speed. Ambient temp right now is 98F.
Vent temps were showing 63F.
