Abstract
Systems and methods for identifying relay contact position within an appliance. In one embodiment, an appliance includes a first motor, a second motor, and a relay. The relay can be configured to be adjusted between at least a first position associated with a first circuit of the first motor and a second position associated with a second circuit of the second motor. The appliance can also include one or more control device(s) configured to identify the position of the relay within the appliance. For instance, the control device(s) can provide a test signal to the relay and detect an output signal that is based at least in part on the input signal. The output signal can be associated with the second circuit. The control device(s) can determine whether the relay is in the first position or the second position based at least in part on the output signal.
