Rated 1.3 out of 5 by 8reviewers.
Rated 2 out of 5 by DisappointingPurchased motor on 6/6 installation went well. Motor ran very well. compressor ran every 6 to 7 minutes for 3 to 4 minutes.Today (6/16) it sounded like it was single phasing (i know it is only a single phase) them quit seconds later. found a hole (plug in end of cap between leads) in the start capacitor, small amount of liquid in run capacitor. no clear reason why.Grainger is working with us to replace this motor June 16, 2016
Rated 1 out of 5 by Three time using this motor. The first lasted 2 days before clicking and rattling started. replaced with another. It lasted 1 1/2 years. I received a third motor. This one clicked and rattled when I first turned it on.I'm replacing it with a WEG this time. A few dollars more but worth it if it last longer and runs quiet. April 17, 2015
Rated 1 out of 5 by It's as bad as everyone says. Lasted ~3 weeks before it smoked. Thermal breaker didn't even trip, the main breaker tripped and now I have a compressor room that's covered in soot and stinks. Lucky it didn't start a fire! August 1, 2014
