Replaced Trane Rotoloc compressor ( liquid bypass stuck open) Pressures unknown...
Pulled out 9Lbs R-22 before swap...
Replace compressor, charge in 9 lbs R-22 liquid bypass on new compressor opens... Liquid line from condenser starts freezing up....
Yes, I said the liquid line is freezing up:eek:
Pull cover off of condenser and see a small torpedo filter drier that is the flash point (ahhhhh obstruction). Pull little drier and put in a full size Sporlan.
While working I happen to notice the data plate, Factory charge 5 lbs...
This is not good at all....
Start recharging after drier swap, things are going well until I hit my head pressure top end and am still below freezing on the suction (5.5 lbs with liquid bypass closed):mad:
WTF.... check blower airflow (supply and return good), Pull evap coil (clean)....
Pull #80 orifice (clear)
Here are my thoughts, Someone before me overcharged this system ( probably charged it while the bypass was opening:eek:) thinking it was just low charge, The origional problem was / is a system obstruction.
I'm going to focus my attention on the evap coil ( partial clog at distributor) and go from there.
Your thoughts?
