offcntrWell, that was... unexpected.
Sometime last month, the heater in Denise's bathroom failed. It's a built-in Cadet model, with a thermostat knob, but also wired to a light switch on a shared plate with the exhaust fan. Sparked when she turned it on, made a burning smell. Thought it might just need cleaning out, so I took it apart, vacuumed the elements, and put it back together. On testing, the elements heated up, but the fan didn't turn on, so I took it apart again. Didn't see any obvious shorts, arc damage or loose wires, nor did it seem possible to remove and replace the motor. I put it back and reattached the cover, said she'd have to use a portable heater until after Holiday Market.
This afternoon, I took the face plate off to photograph the model number and specs, then went off to Jerry's to get a replacement. They didn't have the exact replacement model--the original was a 1600 watt, 120 volt unit. They had a 1000 watt model, or a 1500 watt that took 240 volts. Since I wasn't willing to rewire all the way to the breaker panel, I bought the smaller unit. It was the same size as the previous one, so I didn't have to cut drywall or install the "can"--the heater equivalent of a switch box. Just unscrew the cover, swap out the heater, connect the wires, and put it all together. Simple, right?
Except this time, when I pulled out the heater, I noticed something I'd missed before: a nail sticking into the back of the can. Closer examination revealed a corresponding puncture mark in the electric motor's transformer. Sometime last summer, the crew installing our new siding put a stake through the heart of our wall heater.
I got out my Dremel with cutting disk and a pair of pliers, clipped it off flush before installing the new heater. And now Denise can dry off from her shower without freezing to death.
