remove the pcb in the fascia panel.mark all the connectors and then remove them from the pcb.unclip the pcb from the fascia panel.now with the control pcb board in you hand split the white plastic pcb housing open.remove the pcb from the plastic housing and you will see the relay and track and if its burnt you will see burn mark on plastic housing
