Abstract
A range hood having a sleek, modern appearance has a keypad and control circuit which enable adjustment of fan speed and light intensity. The range hood includes a keypad having a linear array of keys which may be individually or collectively used to energize the fan at one of a variety of speeds. A control circuit responds to depression of one or a group of two of the keys and in response selects one of a plurality of possible fan speeds. The array of keys is also used in conjunction with a separate night light key to program the intensity of the light for use as a night light. An automatic shutoff key is used to gradually reduce the fan speed until, ultimately, the fan is deenergized.
