thanks for the info, i tried to put it on a switch till i fixed it the right way but when i wired it up the other fan turned on and would not shut off. not sure why that is but i'll get a new thermoswitch and see what happens. i've had the brat for over 10 years and never had a problem with anything before so hopefully this will fix it for another 10, or till she rusts away. thanks again.
