Heh. Strange coincidences – Just spent most of the afternoon dealing with the after effects of a power “bump” and outage at work yesterday evening.. You’d be suprized how much electronic dohickymajigs they can cram into a simple automatic door… and how sensitive those thingy’s can be. The really scary thing is that even if you have to replace your whole machine it will probably be cheaper than fixing the doors. ($240 just for one glorified electric eye! And there are usually 2 per door. That’s just the sensors … I don’t want to think what the control curcuitry will cost to replace.)
