    Default Attic fan motor replacement

    Hi everyone, this spring, I did a favor for a family member and a friend by replacing their motors in their roof mounted attic fans. They had both stopped operating. I bought the motor replacement at one of the "box" stores. They are a 1/7hp motor. To try to make a long story short, one worked fine all summer as it was supposed being thermostatically controlled. The other stopped working in about a week or two. The original motor in this second application wasn't an original and I'm not sure what the HP would be. It has a small housing and blade though. My question is: should I assume that this motor was bad and simply just replace it with another of the same? I bypassed the thermostat and the motor didn't run. Should I maybe try another with a different HP? I'm going to troubleshoot starting with the power source, thermostat on down to the motor. I'm thinking about replacing everything (thermostat, motor, blade) with a unit that will fit into the housing. This way I'll know that everything should be properly matched and working properly. Thanks for any advice.

    Replace the whole thing. That's what I'd do.

    ditto dj, it's too easy to mismatch the parts.

    Good Luck from Columbiana, Alabama
