Since my RV is over in my storage locker, I don't remember if the fridge is a Dometic or not. If so, this might be useful:
"I found out about this too late, but maybe this information will help someone else. A few weeks ago, the upper hinge on my Dometic fridge door broke and the door fell on the floor. I then noticed that the freezer door hinge was also cracked and ready to break. A call to Dometic confirmed that the only fix was to replace the doors. I invested over $300 in new doors. Today I found a post on a "Sportscoach" site that mentions a less expensive route. The following is quotation from that message. "The upper freezer door hinge broke on my Dometic refrigerator. I checked with Camping World and other sources and was told my only solution was to buy a complete door for $150 or so. Not liking this answer I called Dometic. They said that kits are available to repair all of the door hinges and are available through All Seasons RV Appliance Parts & Service in Elkhart, IN. You can reach them at 800-348-7697 or 800-344-0673. The upper and lower hinge repair kit cost $18.95, can be charged to a credit card and shipped anywhere and that they have any piece that you want. Since having this occur I have talked to two others that have paid for a full door ($350 or so) as well as a freezer door. This company is a valuable resource for us to know about.”
The most common reason for hinge failures is doors that have not been adjusted. If you refer to Technical Article # 7 on our Website
www.rv-partsplus.com you will learn how simple it is to adjust the doors and eliminate the costly replacement mentioned above."
Don't Know if this helps, but hope it does.
