Using an allin key & screw driver, remove the screws holding the stainless steel door liner to the door. Carefully separate them - there's one allin key between the 2 door pieces that needs to be removed to separate the electric control module.
The door catch will come out easily - it has a couple of plastic guides that hold it in place.
Replacement part #521809 (obsolete part# 521558)
Put it all back together & be careful with the very flimsy plastic guides.
