Garage Fan Control Photos

The 14" exhaust fan us installed high up in an exterior wall. It draws 2 amperes.

The Control Board is fastened high where its 4 LED indicators are directed at the side door, where the garage opener push-button is located.

The Limit Switch is a microswitch mounted above the door. It is actuated by an extension of a springy Meccano sheet bolted to the top of the door.
