Disconnect the wiring harness connectors.
Put the dispenser control panel aside.
Remove the four screws in the door dispenser housing.
Slide out the housing and disconnect the target switch and dispenser light connectors.
Spread out the locking tabs and remove the switch.
Push the chute duct door locking tabs back and raise the assembly above the locking tabs.
Push the lower armature locking tabs (under the assembly) back and lift up the entire assembly.
Check all parts shown on the attached diagram.
Post your findings.
