I never seen anything like it.

Here it goes.

I built the AC system, pretty much.

Some decent lines, decent looking compressor, bad dryer, stocker evaporator core, TXV and condenser core.

I evacuated the system for about 45 minutes, pumped it with one can then another one.

Nothing, the AC vent temp is 85 degrees.

I added fresh oil to the compressor and blew out the lines before I put it under vacuum.


Pressures are 35-40 & 200-230

I monitored the pressures as added each can. Compressor kicks in and out. Blower motor hums just fine.


Can I get a WTF?

 

Oh yeah, fans are on and running at all time the AC is.

 

Ten years later....: that is your evap core busted.
