Craptastic
By BSA Parent
Motor spindle was built "off center".It took mods to the furnace mount and spacer washers on the motor bushings to align properly, and prevent the fan from rubbing in the furnace enclosure.This took a couple of days of tinkering to "dial it in", where it should have been a 20 minute part swap. It would work for a couple of cycles, and then the vibrations would move the motor the tiniest fraction of an inch. This caused the fan to rub enough to stall the motor, thereby causing the system to shut down, as a safety feature. (Power vent expels Carbon Monoxide to the outside).My HVAC Professional was NOT happy. I finally stopped calling him, and finished the tinkering, myself.Thankfully, once modified it worked correctly - as I was forced to accept it as is, because the temperatures here were single digits at night **grumble**I would expect that alignment of that spindle, being crucial to correct operation of the fan, would be a quality assurance test at the manufacturer's level, before shipping the part to retailers. This one sure did not pass any such test...Perhaps I received a factory second? - I don't know.I do know that next time, I will pony up the extra 30 bucks, and buy the part at my local HVAC shop, so I can avoid this kind of headache again. If I could have driven to the HVAC shop, and exchanged it, I could have had a warm house, two days sooner.Do not order this part online, if you are in a time crunch. If you do, when the part arrives inspect the placement of the spindle, in relation to the center of the housing. Make sure that the mounting flanges are properly attached, and spaced EXACTLY like the motor you removed from your furnace. Alignment of this part is EVERYTHING, and improper alignment is an unmitigated nightmare.Good Luck.

Furnace Motor
By JK
The motor had to be shimed for installation due to brackets being a little off due to being bent in shipping,The motor works as advertised, but is no longer AO Smith branded, they were bought out by another company.

Works good.
By Thomas Paul Murphy
The old motor was getting hot to the touch. And what I was told was the ceramic bearing had been screeching for years. This motor solved the problem. I have also been told that the original motors in this type of furnace are the first thing to go about it because of the initial surge required to get them going. More modern furnace motors that function as the inducer motor have a step up system whereby the motor comes to speed in a serious of steps and thereby eliminates the "surge heat"Also the most modern furnaces have a variable speed like function to them.The thing to remember is that when you replace this motor also replace the blower wheel on it. Now here is what most people will never understand about centrifuge fans; They are blowers that are enclosed in housings with an air inlet and an air outlet port. If the blower wheel is not placed on the critical dimension from the side of the fan housing closest to the motor, as defined in the instruction manual, that blower fan can cavitate air inside of it (the same principal of being caught under the base of a waterfall) and when this happens it can lead to inefficient air quality and also poor furnace efficiency.Essentially it means that air is not blowing through the blower housing but instead escaping the function of the blower motor by creating a cavitation air pocket.If you have a man regularly service your furnace and he removes this blower fan to look at it make sure that he reinstalls it at the critical dimension. If you look on the arbor coming out of the motor and see that it has been scored from the set key in different critical dimension lengths it means that at least one of them was not correct. And it is impossible to know whether it was the original furnace setting or the man who came to yearly inspect your furnace who mis-set the critical dimension. So before you take the blower fan off measure that critical dimension when you have it separated from the clam shell housing, to see if it is currently correct.The air in your home will be much fresher when you get this right.The old motor was very hot to the touch, So much so that you could not hold onto it. Also when that furnace inspection man comes to your house make sure that he plugs the Electrical connector for this motor ALL THE WAY back into its housing for if he doesn't it creates a lack of current to the motor that heats up the motor to failure!This new one does not get hot!"We are all in this together!" a quote from the movie Brazil.And if you have no competence with regard to mechanical ability don't pretend you understand things you don't. Don't tamper with your furnace but make sure to ask questions.Copyright 2013 Thomas Paul Murphy
