Hello,
I removed my Fasco 7021-11577S when the bearings went bad and ordered the A225 OEM replacement. I notice that when mounted this new draft inducer it whistles really loud .Is the hole in the back of the draft inducer supposed to be flush against the hole in the furnace because there is a space. The old draft inducer assembly had some type of foam or rubber ring glued to the back of it . Seems like there isn't a replacement that has that . Any help would be appreciated thanks
