My Kenmore Elite freezer door came off one of its hinges. I cannot figure out how to put it back on so that it stays. The connection has an upper hook with a lower hinged arm. It is strange.

I just spent the better part of an hour on this. There is a white flange with two phillips screws. If you take this off it is easier to see the mechanism, but you may be able to get it back on without removing the flange. I removed the flange. The mechanism attached to the door has a hook facing up and a smaller hook facing down. There is a hinged metal bar below this. The bar has a hinged piece with a loop on it. Pull the loop up. Now push down on the piece with the hooks ( it has a spring) and hook the smaller hook on the loop. Do this for both sides. Now the door should slide easily into the slots. Once in the slots, push down on the hook piece and release the loop. Push the loop back in place along the bar. Hopefully this does the trick for you, it did for me.

heres a video showing how the two metal pieces hook together. It's hard. You really have to put out and almost use two hands.

This takes some acrobatics with the spring loaded hook. First, on The smaller hook, push the locking clip flush with the hook. Then draw both hooks together before you insert into the door. I dismounted my door from the track so that I could manipulate the spring loaded hook out from the door, while guiding the smaller clip in underneath - when you get the right angle, it will slip into the slot below the slot the larger hook goes into above. This may look impossible until you push the spring loaded hook down and pull the top out a bit. Watch your fingers. Once it seats, then you can pull the hinge fully open, push back the plastic molding, and open the little locking piece, which had to be closed flush with the hook when you started. This thing is ridiculous, but it can be fixed. I’m sure it can be done with the door mounted, but I’d rather not torque on all that plastic and slide rails. Just two screws allows you to dismount the door frame from the track. Do it.

It is strange that the door came off. If it did not brake.. laying the refrigerator on it's side,or getting a friend to help hold the weight while you secure it should work.
