Well, the house air conditioner has now huffed it. Fearing that the new dog, whose chewing instinct is prodigious (he previously chewed a couple of boards off the back of the house), had gnawed through the wiring, I went out into the jungle that is my backyard to examine the unit. Nope. Fortunately the rawhide chews we bought seem to have preserved the A/C. But after checking the breakers and fuses, it is obvious that the unit has power, it just won't start up, emitting a click and a low electric whine like the fan is trying to start but is obstructed. However, an inspection of the fan blade/motor revealed no such simple obstruction. Any ideas? Can't call a service guy. They have a distressing habit of wanting a not-inconsiderable amount of money to do their black magic.
Well, have two doctor's appointments this morning, so I'll try to have more later.
