This evening, a friend of mine changed out the thermostat on a large industrial electric range. In the process the process of removing and disposing of the old sensor tube, he broke it.
He chucked the thing in the garbage, and within a few minutes, it started to heat up and catch the garbage bag on fire! The tube was room temperature when he removed it.
I walked in at about this point and checked out the damage. As we were talking, he shook some of the collected dust off of the old thermostat (not the sensor tube, the thermostat itself), and it spontaneously sparked up.
Both of the fires were very small, but I’m completely boggled as to what caused them. Any ideas?

when the thermostat shuts down air conditioning/furnace unit I lose power to almost all of my house and when the unit turns back on then the power returns to all the items that lost power.
