motor start capacitor
Well, I got the capacitor from Grainger and the door opener works
flawlessly now. So I've no idea whether the original failure was a
freak coincidence or not :-)
I hadn't realized that Grainger only sells to businesses/institutions,
but the guy there helped me out by pointing out that my employer (U of
Maryland) has an account, so I was able to buy it. Woohoo.
