Abstract
A moisture control device and method has a heat generating source in electrical devices that is powered to operate independent of the electrical device for reducing, minimizing or preventing condensation, nucleation and degradations on electronic parts and circuit boards of the electrical device. A power supply is connected to the heat generating source and a switch connected to the power supply. The switch may be manually operable or automatic and is used for controlling operation of the heat generating source. A sensor senses on/off status of the electrical device and automatically operates the switch in response to the sensing. Power is supplied to the heat generating source when the electrical device powers down and disconnected when the electrical device powers on.
