Summary:Appliances that include a ground fault door latch trip circuit that leverages a door latch circuit of the appliance to open one or more component relays upon detection of a current leakage event are provided. In particular, the ground fault door latch trip circuit can provide one or more shunt paths when a ground fault event is detected. The shunt paths can shunt current from a door latch to ground, such that the door latch circuit operates as if the door of the appliance has been opened.
