My home was built in 1940. It is a 1 1/2 story house with full basement. I just replaced the AC and furnace with a dual fuel Rheem heat pump and gas system with the blower unit located in the basement. For any number of reasons that I'm sure you could start naming, the AC does not do very well on the second floor. There are three floor vents up there but I'm sure the cold air sinks to the first floor before it cools much.
The house has an attic fan mounted upright in a tunnel. The fan pulls air from louvers in the second floor ceiling, into the tunnel, and then exhausts into the attic where it leaves through the gable ends. The ceiling hole is also the peak / attic access (remove the louvers) and it is 20" X 20". About the time I was having the new system installed last fall the fan quit. I asked the contractor to take a look at it to see about getting it running again. He didn't have time when installing the HP/furnace. However, he was here a few days ago to check the humidity control on the HP/furnace. I got him to check out the fan at that time. Not good. Motor shot. We need help finding a replacement motor.
The motor is a Fasco, but they are not able to cross reference it. The control for the fan has three speeds and also a timer for the on/off. I'm hoping someone here will have some old material which will give me an idea of what to replace it with. The numbers from the motor:
Fasco 4 pole motor. It is a direct drive connection to the fan.
Rochester, NY.
4A1A61R
115V
2.3 Amp
Shaded Pole, Clockwise shaft rotation and 3/8" shaft.
Any help sure would be appreciated. I don't use the fan very much but it sure does a good job of getting rid of some of the heat up there and pulling some more cool air to that floor when it does get hot. One suggestion the contractor made was to just get one of the gable end fans and put that up there. It would fit but I don't believe it would work with the different speeds. And I've seen some of the "Whole House" fans but they are pretty big and won't fit through the hole, making for a big carpentry job. That is not very appealing either.
