As an update, I ordered this
https://pdxrvwholesale.com/products/...it-29326430300 to repair my broken hinge.
I had a heck of a time getting it last year. I think I ordered and paid for it 3 times, and each time the seller canceled and refunded after a couple of weeks because they couldn't get the part.
I tried again about a month ago, and this time the kit arrived with no problem. I had intended to replace everything, since I had all of the parts, but when I looked closely I realized that each hinge has two screws that go in from the front (easily accessible) and one screw that comes in from the side - which would necessitate pulling the whole fridge out by at least a couple of inches.
I decided to just replace the damaged pin, which was the silver threaded pin near the center of the photo.
The door works fine now, but I am looking for a replacement for the door side of the hinge. It is plastic and a portion of it was broken off in the initial mishap.
Hope this helps someone else who may have made the same (dumb) mistake that I did!
