Any pointer on how to identify the bigger one?
I notice, sometimes it said LTR4?
So far, the AC works after putting 4lbs back in it.
We will see how long it last.
The 11 CU in unit has a "11" on the back casting of the compressor in 1" high numbers.
From the other thread: The A6 was a good compressor but, I have seen them get ruined (lock up) as well. I would go through the trouble to put an A6 on.
