You can see if there's an installation maqnual to download. You can check your owners manual for a service number. Possibly Tech Support can instruct you on how to adjust the door. Or determine if you need new hinges or other parts. Frigidaire is the named manufacturer. Find the serial and model number info for when you call. If you want to wing it you can prop the door up and examine the bolts used for the top hinge. Loosen them and see if the hinge can move.

Depending on how the hinges are designed, a nylon washer of suitable size could be placed on the bottom hinge pin to shim the door up a bit.

Thanks to all who responded and the suggestions. Now to figure it out!

What I’ve learned since posting is that Frigidaire has no serial number on record for this freezer sold by Home Depot. What I learned from a friend, who got down on the floor to see the lower hinge, is that the hinge is bent. He went to the trouble of cutting me numerous blocks of wood to support the hinge once it’s back in place. Moving on to raising and supporting the hinge to see if I still need plastic washers.
