Attic fans and windows should be at least thirty feet apart.

Your attic fan may not be turning on because of an electrical problem like a tripped circuit breaker a blown fuse or a bad connection.
Took the panel off and the fuse was blown again.
During the summer an attic can be 40 to 50 hotter than the outside temperature which in turn heats up the house very quickly.
Make sure the attic windows are open and have the proper distance from the attic fan so there is an airflow for the attic fan to pull in.
With an attic fan you can cool the attic to the same temperature as it is outside greatly reducing the house from heating as quickly.
So i replaced the fuse put the panel back on and it didn t turn on.
So a few months ago my ac wouldn t kick on nor the fan or furnace.
If the attic fan isn t turning on it could be an electrical issue a problem with the thermostat or the motor of the fan that s not working.
When an attic fan isn t getting enough air it sometimes will begin to rattle or shake.
Loud noise coming is from attic fan.
And it was blown.
I did some researching and found out it was the 3a fuse.
