Our attic fan has stopped working-- I got the model # and contacted the manufacturer, who suggested wiring the fan directly to the house power (leaving out the thermostat) to see whether it's the motor or the thermostat that needs replacing. They also gave me the part numbers for ordering a replacement motor and/or thermostat. My question: is this a reasonable "do it yourself" fix, or a job for a pro? I am very capable of following instructions carefully and have done some very basic wiring (putting in a dimmer switch, etc)-- but I also know that some things are better left to others. For instance I understand that some motors have capacitors that carry a charge that must be drained before working on them and am not sure if this fan has one or not. If it's a job for a pro, would I save any $$ by ordering the parts myself? Thanks!
