My freezer door spring on one side is broken, door stays open. On mine I can see there is a small clip on each side, I think the spring is inside there. For the time being I've used a small piece of Velcro on the door and matching piece on the side. It seems to hold it closed so it doesn't flop open when the fridge door is opened. The freezer door is easy to open and close, I guess I got it matched up pretty good to work that way. It's on my honey-do list.
I see a replacement in the PDF for my model Dometic fridge. Did you check their website for a parts list?
