One of the problems with being an engineer is that I have ideas on how to fix things and it takes a lot for me to have someone else fix things. Lately we’re been having problems with our microwave door closing; it was just sticking. So, I finally got annoyed at it and decided to take a stab at fixing it. I figured it just needed to be lubed up, but what type of lubricant would work that wouldn’t blow up. I had WD-40, but that was a bad choice as I thought that it could be smelly, wasn’t good around food, and could blow up the microwave. My second choice was a bar of soap. Sounds stupid, but what did I have to lose. I used a bar of Irish Spring (it makes things smell better) to lube up the prongs on the door that go into the microwave. That seems to have been the ticket; after less than a minute of trying to fix the microwave, it was as good as new!
