I had to replace the exhaust blower in an ICP 90+ furnace (part
#1164280) after the unit was in service five years. The original part
developed a bad vibration, then the plastic blower wheel self
destructed. The replacement part is now getting "noisy" according to
the customer. I checked it out and there is a vibration like this
blower wheel is out of balance, but the furnace is still functional.
My question to others out there: Have you been having problems with
chronic failures of this part or was I just unlucky enough to draw a
bad one off my suppliers shelf? Heating season is almost over and I
normally don't stock this part anyway, but perhaps I should have one
on hand just in case I get another call on one of these units for this
I looked it up on The Web and suppliers sure are proud of those
darn things, the lowest price I saw was $171.00 . There are 2
motor repair/rewind shops in town that I deal with on a regular
basis and the guys there have been able to come up with metal
blower wheels for those draft inducers. It looks like it can be
taken apart. Perhaps you have some well stocked electric motor
repair shops in your area?
