Abstract

A fan apparency arrangement for an appliance is disclosed. The fan apparency arrangement includes a chamber having a port; a fan in the chamber for moving air out of the chamber, the fan having a discharge end, and an intake end having an intake tube; and a sail switch disposed in the intake tube. When activated, the fan moves air out of the chamber through the port and creates a pressure difference between opposite ends of the intake tube, the pressure difference causing the sail switch to change position and signal that the fan is activated. An appliance incorporating such a fan apparency arrangement is also disclosed.
