About 18 months ago, I purchased, for my gunsmithing shop's air compressor a 10hp single phase motor, from Phoenix Phase Convertors, a local business and reseller for North American Electric, Inc.
As you can see on this page, the description clearly states "24 month warranty". On or about October 12,2012, the motor, which had been working fine, started tripping it's 50 amp breaker regularly.
I contacted NAE and was directed to Mr. Dale Bostian as my rep.in a few days, at his direction, we had taken the motor (which weighs over 100 lbs!) to a motor shop in downtown Phoenix, about 50 minutes away, for "inspection". Phoenix Electric Motors, inspected the motor and declared it "fried". They forwarded an inspection report to Mr. Bostian who not only shipped us a replacement motor, but had his company send a check for Phoenix Electric Motor's inspection fee of 45 dollars!
Great right? Wrong!
Less than SIX WEEKS of actual use, the new motor start tripping the breaker.
