What perfect timing on reading this post.
My Microwave has a little bit of a stick to it when I open it and I thought when we got back home after the this past weekend outing I was going to WD40 it. Hmm, now after reading these posts it has me thinking the "STICKING" is not such a bad thing after all.
All our trips out on the road with the camper, bumpy roads and all, and never a problem with the microwave door coming open. So I guess the old saying goes...." if it ain't broke ( just slightly stuck ) don't fix it".
Some great ideas being tossed about here...but in my case I think I will leave it.
