I was in the shop this morning to do some injecting but smelled something really warm. Not hot like in burning but just really warm smelling. I check everything and found zip then noticed the display light on the microwave wasn't on, so I went and checked the breakers. Nope, nothing tripped so I went back to check the microwave and sure as heck it was super warm to the touch. The plug was cool but the microwave cabinet was plenty warm to touch....almost to the point of being hot to touch. I tries a drill in both plugs of the outlet and things worked fine so I figured that 5 years of cooking plastic was a pretty good run for a $75.00 microwave and a trip to Best Buy got me a new one.
The only things I leave plugged in in the work shop is the microwave and my cd player/radio. Finding this microwave so warm got me to thinking that maybe I should just unplug it between uses. The radio is all digital now so it doesn't hardly have a draw but I'll be giving it a touch/feel occasionally now just to be safe. Best Buy had a nice table top CD player/radio on sale while we were snooping microwaves and one with blue tooth everything came home for the shop today too. The current player's cd function is messed up and with all the cds I have that hasn't sat well with me. So that problem solved too.
Anyway, just making the suggestion that maybe giving some of your electrical appliances a feel every now and again to be sure they aren't overheating unknown to you. This has never happened to me before and it has made me a bit paranoid now.
