[ARCHIVED THREAD] - Replacing blower motor and capacitor

Posted: 5/26/2015 10:20:51 PM EDT

I don't generally like electrical work, but this doesn't seem horribly difficult to do. I was quoted $950 by a reputable company, but I could probably get the parts to do it myself for less than $200.

Only problem will be removing the current motor without damaging the housing unit since it seems to be rusted pretty good.

Any advice before I screw things up? Should I fo?

Generic blower motor should cost ~200, two hours labor tops unless it's a horrible pain to take apart, and the service call. Where are they getting 950? All said and done it should be around 500.

Apply a good penetrating oil ( such as pb blaster or kroil) to the 4 point bolt retaining the fan to the motor shaft.
Sometimes you need a proper gear puller type tool to extract.
If you run into trouble, locate a local shop who is an electric motor specialist for help.
My locality has a specialty shop who rebuilds motors and sells replacements. They're damn good at what they do.

Hell, are they replacing the air handler??? $900 is steep. The hardest part usually is getting the old shaft out of the blower. Sand the shaft and hit it with PB blaster or Kroil. If you have a puller your good to go.

Alright, I'm foing.

I'll spray it with Kroil tonight and see if I can get a motor locally tomorrow. Only problem I may have is finding out which wire went where.

Allow me to post a quote from Red Adair a mans man.

If you think it's expensive to hire a professional to do the job, wait until you hire an amateur.

Point taken, but this is the DIY subform.

Not saying Kroil didn't do anything, but it's still not coming off. I'll have to get a gear puller.

Finished it earlier. It wasn't bad at all. Took me about three hours of labor to do everything, but half of that time was spent cleaning the blower and housing unit. Now enjoying a cold beer in a cool house.

Thanks for the help.

ETA: Gear puller was not needed, although I couldn't find one that would have worked anyway. The tender care of a 4lb mallet seemed to do the trick with removing the old motor. DISCLAIMER: If you go that route, you have to be very gentle because it is very easy to damage the blower or housing unit.
