I had an attic fan installed about five years ago when I had the new roof
put on. I picked it up from Home Depot for the roofers to install. The fan
worked fine all this time but started making a very annoying sound. It works
on a thermostat and set to come on at 100 degrees. I also installed an
override switch in the hallway to shut off the fan.
My question is can just the motor be swapped out. I don't want to change the
whole unit and mess with the roof tile. I went to HD and they do not sell
motor assemblies. Any ideas where this item can be purchased.
Before you do that, check for places to oil on it. Some motors still take
oiling. Would be best you had the instructions. If you think you are going
to have to dump it any way, I would spray the heck out of it with WD40 and
hope a seized bearing starts turning again. I did that once and the fan was
like new for at least 5 more years till I moved. Also those fans may be a
waste of money. RIdge vents are better. Attic fans suck the ac out of your

Look I can buy the replacement motors for the roof vent fans and you can go buy a new
complete fan for about what I can buy just the
motor for. Buy a new fan for about $29.00 to $49.00 and take the parts off it to put
on the old one.
Now do look for oil holes on the motor to oil it and it will keep going and work
fine. They recommend 20 or 30 weight plain motor
oil to oil it with.

Just thought I would add that when I put in a fan in my previous house
(something I would never recommend and never do again) I found most of them
had small crummy motors but Sears had 2 models and one was 3 times bigger
than anything else on the market. DOn't have the house any more and don't
know the exact sizes involved but he should take a look at what he has
before buying a generic replacement. Might not fit.

you probably went to the wrong home depot.. the one i go to has two
replacement motors for the ventilators they sell... or you can look up
the manufacture in the web and go to their web page and get a 1`-800-
number and call them up to order a new motor via the credit card
I did this exactly. Mine made the same noises. I contacted the
manufacturer and they sent a replacement motor, even though it was
slightly out of warrantee. Been working fine since...
