Abstract

A disposal assembly includes a motor coupled to operate a grinding mechanism of a food waste disposer. A first switch is coupled to selectively inhibit the supply of power from a power source to a main winding of the motor, and a second switch is coupled to selectively inhibit the supply of power from the power source to a start winding of the motor. A control circuit is configured to close the first and second switches during an initial startup time period, detect a voltage of at least one of the windings, and open the second switch in response to detection of the voltage above a start voltage threshold value. The control circuit is also configured to subsequent to opening the second switch, close the second switch in response to detection of the voltage below a low voltage threshold value indicative of an excess load condition of the motor.
