Abstract
A dry out mechanism for controlling a humidifier is disclosed. The mechanism includes a float and a switch. The float contacts the switch when the float is within an operating range. The movement of the float can be manually changed between settings to achieve normal operation or dry out operation of the humidifier. In the normal operation, the float activates the switch based on the fluid level within the humidifer's reservoir. In the dry out setting, the float activates the switch independent from the level of fluid within the reservoir so that the humidifier depletes the reservoir and components of fluid.
