Just randomly checked this thread...I've been using this fridge for almost 2 years now.
I took a slightly different path for the door...I just peeled back the rubber gasket a bit, removed all the screws, then took out the entire insert. When i put the gasket back in, it didn't have a 100% perfect seal anymore (between the screws it would "open up" a little bit). So, I went to HD and got some really inexpensive plastic sheets, and cut/drilled them so that it goes plastic - rubber - door again, but without all the parts sticking out the insert had. Works great now. For the light, i just used a small piece of gorilla tape on the switch. I didn't find the light useful anyway.
If you don't want to ever be able to put the door insert back in, instead of plastic, just use some silicone sealant to hold the rubber on the door.
The main reason I went this route is that there's a good chance i'll want to use this as a regular refrigerator again - I was thinking I'd be jumping to a chest freezer at some point . Glad I did, as the freezer is now in the basement waiting for conversion.
