Whole house fan only works at one speed.
1/2 hp motor on belt driven fan. When switched to high it sounds as if it's trying harder but there in no noticeable increase in the fan speed. I had worked in the past.
Time for a new motor or is there a replaceable part like a capacitor that might do the trick?
Thanks in advance.

There may be a run capacitor.
A nice clear well lit picture of the motor label would be helpful. http://www.doityourself.com/forum/el...-pictures.html

It's a split phase motor but no capacitor.
According to the motor plate it's an oilable bearing motor. Has it been oiled ?
That may help.
Just as an FYI.... the most cost effective replacement motor I could find would be a Dayton 6K394. You could search around for that number at the best price.

wow..they cost almost as much as a new fan. Might consider just replacing as it is kind of noisey and the baffles don't close well. I noticed it needed oil when i took the pic. I will handle that soon and I have never done it but I assume there is some little port with a cap to inject the oil. Easy enough. Thanks for the help.
