Fan in the bath at house B stopped working. It's integral with and therefore on the same switch as the light. So I opened up the fixture and found a dead motor. This is an older NuTone unit, and g.f. found a replacement motor on the web for around $20 plus whatever tax/shipping might apply.
We could have been satisfied with that, but I unwrapped the thing to find a thermal fuse. Trip to "The Shack" (isn't that just the cutest darn nickmame?) and although the guy there had no idea what a thermal fuse was, I had the part number handy from their website. $1.99 plus tax, $2.16 total.
So I'm thinking, what would this repair have cost me if I'd hired an electrician? Probably a complete new unit at $100, plus $150 to install? How do people who can't do one little thing themselves survive? I'm nowhere close to being the DIYer that a lot of you are, but things like this come up all the time.
