For my application, I just MAKE SURE that the pin at the top of my small Norcold is fully engaged. It is possible to push the Refer closed, hear a click and realize later that the fridge is not really latched. Usually this realization comes when something dense comes flying out, with everything else just behind it.
We just close the door, then give it a really firm push near the upper right corner and nearly every time find that the pin that secures the door was not fully seated.

But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. Romans 5:8
