DR Cillaliz, your visit from the fire department reminded me of the time the heating element in our oven ignited while I was pre-heating it for dinner. We had a ladder truck, a pumper, and a couple of administrative vehicles here and one of the firefighters said, "Wow, I've never seen an oven do that!" No fire, no damage, no home-cooked dinner that night.
I hope all is well at your house...
