Original part discontinued, new switch functioning properly
Saved my 20 year old compressor. The first switch I received from ereplacementParts.com was the wrong pressure range. They happily sent me another kit which works great. The pressure range is correct, and it cycles perfectly. The configuration was slightly different, but all the components fit to the new switch without modification, except the unloader tube had a different connection fitting, but everything was supplied and worked just as intended. If you are replacing a CW207579AV, its a good bet this is the one you want.
Excellent customer service, speedy shipping, easy return on the first switch, couldn't ask for a better experience. eReplacementParts.com will be my first stop next time I have a need.
