Broken door latch

Disconnect the power,open panel and remove screws with the exception of the two bottom ones. This allows the panel cover to be opened far enough to pull latch assembly clear.
Remove electrical contacts (2) and put defective unit aside. Connect new latch unit to both wire saddles,line up unit with proper holes and install two screws. Once fixed in place,install all other screws and switch power back on.Do a short test run to check for any leaks
