Attic fan

I believe you are talking about a whole house fan that pulls through the ceiling into the attic, but it would seem to me that the principle would be the same as my experience. I have a power vent fan that pulls air out of my attic, drawing it up through the eaves and out the vent fan. When the motor crapped out I bought the same size unit and then disconnected and removed the motor/fan, installing the new motor/fan and reconnecting. Much less work than tearing the fan housing and flashing out of my roof, which was not necessary.
So why go through the trouble of removing the attic fan framework/assembly? The key would be to find the replacement motor or motor/fan assembly that is an exact fit. If you can find the same unit, it would seem much easier to replace the "guts" than to tear out the whole thing....

Just replace the motor. Not a big job. Should be 3 bolts holding the motor frame together. Wiring is basic
Much easier to replace the motor than the entire unit. Make sure the power is off and if possible, install an on/off switch while the power is off. These motors are never lubricated after installation even though they are designed to be lubricated with a few drops of oil. Then they sit all winter with no usage and freeze up. I've had to replace mine a couple of times. Lowes or almost any big box or electrical store will sell the motors alone.
A while back , I posted questions about a Whole House Fan. You may find some of the responses useful. I have come to Love My Whole House Fan and it is very effective.

I've bought the "whole thing" only to use the motor....... Perhaps twice in 27 years. Just don't do it when it's 80+ out......

If you can find an exact replacement for the existing motor it will be easier and you can save a few bucks by replacing just the motor. If it's an older unit finding an exact replacement might not be an easy task, especially if the motor was made specifically for the fan manufacturer and has non-standard mounting.
