I replaced the motor and thermostat on my attic exhaust fan a few days ago. It's working however the fan seems to turn on and off much more frequently than it should. Sometimes it will turn on and run for a couple of hours and other time it will run for a few minutes and shut off, then turn back on in a minute or two. Maybe I got a bad thermostat...? Was going to try to replace the thermostat again and see what happens but its hot up there so I thought I would ask here first. Any recommendations / help would be much appreciated. Thank you in advance!
