The Dometic fridge in the 17′ Casita has a weak plastic hinge. It can break if it pops open in transit, is overloaded, or by leaning on it while open. Replacing the hinge required a costly new door from Dometic until Little House Customs came to the rescue with a stainless steel reinforcement plate that will help prevent the hinge from breaking. It will also fix a broken hinge.
For this project I needed a drill with a 1/8″ bit, phillips screwdriver, and a pair of 10mm wrenches.
The plastic trim cap on top of the hinge needed to be pried off, I used an old knife. Working with the 10mm wrenches, the lower is used to loosen the nut 1/4 turn, then the top one is used to unscrew the hinge pin while keeping the lower nut from turning. Pull out the hinge pin.
Here I opened the fridge, being careful to not let it drop or flop, and laid the reinforcing plate on top of the door. Re-insert the hinge pin to hold the door through the plate and nut and screw it down while keeping the bottom nut from turning with the wrench. Then tighten up the lower nut.
I drilled just one hole before inserting a screw by hand before going onto the next hole. If you drill them at all at once, they might not line up. It’s soft plastic, so no power tools or the screws can strip out.
Installation complete. With the door closed you can barely see it.
