Oh Lord, you mean rebooting the smoke alarm fixed it.4

Everything seemed to go at once last week. The ceiling fan, on a dimmer switch was strobe-lighting and otherwise freaking out. So I pulled that down and bought a replacement. When I tested the old unit with new bulbs it worked fine but the dimmer was working oddly. Hell, I can live without the dimmer so I put that unit back up and returned the new.
That's about when the batteries from the smoke detectors started chirping and just like you say------even with the green and red flashing-------you can't easily figure which one is out, if any. So I played that replacement and reset game with all 4 units. All of the batteries tested good. So none of it made any sense. Put it all back up, reset the system and it hasn't chirped since.
Fridge water filter dispenser was also on the fritz for about 3 months. I replaced the filter and that didn't do anything. Finally I rolled the fridge out and pulled the water lines up off the floor, jiggled them around and straightened them out. That was a winner.
A bunch of other piddly things like that all went off at once. This is when I'm glad to be retired. It was really horrible dealing with that kind of crap when I was already overworked and overstressed.
Blew me away when that fixed my TV.
