ABSTRACT:
A dehumidifier includes a humidistat switch to provide power to the compressor and fan when the ambient humidity exceeds a given level. The power to the compressor is also controlled by a thermostat switch and a timer. When the dehumidifier is operating in an environment that is below a given temperature, the compressor is periodically turned off for a short interval to melt any ice that has formed on the compressor coils.
