SCS compressor replacement - Richard - 12-01-2014
I lost the second stage compressor in my rear unit. It wasn't locked, but it was pulling 14 amps and blowing the breaker. The windings were showing some continuity to ground also. The other side pulled about 7 amps on the bench.
Tom helped me find a replacement compressor, a LG QK164CBL from AC Parts Distibutors in Florida. It was 320 USD. I post this because this is a direct drop in for the Matushita that was the OEM. I had to do a little copper tubing fettling to get the diameters to match up. My high side was an unusual 5/16 tube.
Anyway, there is a neat tool that has stepped diameters on it that you can use to expand tubing to make a male female joint. It's common in the plumbing section of HD.
I wanted to post this picture, because I remember John Clark of Newell customer service fame laughing at my digital fish scale that I use for weighing in charges. By the way, according to the literature the system holds 32 oz of R22 per loop.
I was happy the new compressor was pulling around 7 amps when I put power to it.
The real test will have to wait till warmer weather. I'll know then if I have to adjust the charge.

Richard,
Do you always charge with liquid?
RE: SCS compressor replacement - Richard - 12-01-2014
Mike,
The system was evacuated and I knew the factory charge amount so I charged liquid to the high side. The compressor was NOT running.
When I have a running compressor I charge vapor to the low side.
