First let me thank all, who helped me with my chairs. They are fixed. Next, I have a pretty simple fix for a broken Norcold refriderator door. On my door the long plastic strip, which holds the bottom hinge, had broken out at the bottom and the door fell out.
1. Phillips screwdriver
3. Tin snips
The hinge connection went under the plastic and then two screws held the door in. I went to the hardware store and bought an inexpensive house roof vent (less than $10). I cut a strip, about ten inches long, off the metal vent that was thinner than the plastic strip, which was not broken off. I drilled two holes that the screws would go through, at the bottom of the strip. I then slid the strip under the remaining plastic strip on the door. I then put the door hinge part under the strip. I finished by tightening the screws and the door is better than the manufactured door.
This whole thing cost me less than $25 (including aviation tin snips that I purchased. This fix was a whole lot cheaper than a new door.
