Unplug refrigerator. Use non marring (plastic trim stick) tool to gently pry loose the plastic assembly containing the PCB display beginning at the lower edge and proceeding around the outer edge. Disconnect all connectors and note the routing of each wire harness and connector (take pictures on cellphone as necessary). Remove two screws holding inner PCB mount bracket in place to expose actuator, flapper door and linkage. Replace actuator (three mounting screws) and ensure that actuator "operating arm" properly engages the intermediate linkage and flapper door linkage. The actuator arm on the actuator I received was in the "flapper door OPEN" position.
--- I do not recommend test operating the actuator until properly mounted-----
Replace PCB mount bracket and PCB display. I test operated the actuator at this point to verify proper operation. Snap PCB display into mount bracket.
