New Blower wheel


rican

Recommended Posts

I had to replace my belt driven blower wheel, because the old one was making a chattering noise. Although, the one ordered was stated to be the same size as the old one, what came in was ~1/2 in wider in the diameter. The wheel still fit in the unit with room to spare. I adjusted the wheel as not to hit the housing unit and installed it with the fins in what I thought were the same direction as old. I tested the unit prior to reinstalling it and it seemed to run fine with almost no noise. The old unit ran counter clockwise. I left the new wheel turning in the same direction. Air was being blown out. I reinstalled the unit into the furnace. When the unit turned on I noticed at registers that new wheel was blowing out air at about 1/2 -2/3rds the old rate and from the returns a high pitched winning noise can be heard. Would a larger wheel not push as much air? Might it be turning in the wrong direction? Any help would be great.

Thanks

A new wheel that is bigger should produce more airflow. It is most likely in backwards. a wheel that is in wrong will put out about 30% - 50 % of normal

airflow. see my crappy drawing below for correct blade alignment.
