I changed a condenser motor on a 3 1/2 ton 12 seer tempstar about 6 months ago. About 2 months ago got a call. The motor was making a horrible racket. It acted like the bearing was bad so i replaced it. Now i got another call, costumer says doing the same thing. Has anyone ran into this type of problem. I am using the replacement from the same supply house the unit came from. I am not the original installer but this costumer has had numerous problems with this unit but i connot think of anything that could be causing this.
