Title: Vintage Westinghouse Compressor Wiring Post by: ClassicCokeLover on February 25, 2013, 06:30:45 am On the Westinghouse compressor for the "Junior", there are the three electrical posts, B-W-R. All of the wiring, relay, and t-stat should be replaced. But is there an ohms rating between the electrical contact posts that I can check to be sure it is ok?
Anyone else re-use the original setup? Title: Re: Vintage Westinghouse Compressor Wiring Post by: kbareit on February 25, 2013, 05:07:45 pm To test the windings in the compressor first place one of the probes on the body of the compressor(make sure it has good contact) then place the other probe on each of the posts and see if you are reading any resistance. If you read resistance the windings are shorted to ground and the compressor is bad. Most compressors posts are marked R-run S-start and C-common. Yours are marked B-start W-common and R-run. Place one probe on W and one on R write down the ohm reading. Place one on the W and one on the B and write it down. the B reading should be higher than the R. Place the probes on the R and B and write that reading down. take the readings of W-B and W-R and add them together, they should equal the reading of B-R. If you have any readings between the posts that show no resistance the winding is open or if they all read the same they are shorted together. If you need any help feel free to contact me and I'll help as much as possible.

Thank you! Title: Re: Vintage Westinghouse Compressor Wiring Post by: Creighton on February 26, 2013, 03:31:31 am Great info there!
Thanks, Ken. Creighton Title: Re: Vintage Westinghouse Compressor Wiring Post by: cohammer on February 26, 2013, 08:18:36 pm i am going to save that info for sure

Great Information! Title: Re: Vintage Westinghouse Compressor Wiring Post by: globalcompressors on February 27, 2013, 10:45:00 pm HAHAHAHAHA!!!!! :biggrin:

What I was referring to as B-W-R, were the colors of the conductors and how they were attached to the posts. Since there are no markings on or near the posts themselves. So my resistance readings came out as follows. W-R=20, W-B=3, R-B=23. I'll email you some pics of this. Thanks Title: Re: Vintage Westinghouse Compressor Wiring Post by: kbareit on March 08, 2013, 02:52:58 pm I answered your email before seeing the post. Your W to R is the start winding the W to B is the run winding. Seeing the readings it appears the compressor windings are fine. Anymore questions let me know.
