Product review (5 stars): Good replacement for factory unit that failed
When the local service dealer incorrectly diagnosed a bad compressor instead of the start relay I tried this unit. The compressor checked out good on my meter and the Supco is a larger heavier unit than the overpriced factory one. This is basically a generic unit for any compressor up to 1/2hp. It takes a little modification to connect up but talking to local service techs it has proven to be a more robust starter than the factory unit.
