Hmm...

If the voltage goes low enough to break arc, but not low enough to reset the timer chip on the relay, I could see them misbehaving.

Figure the board prob runs low-voltage 5-20v and uses a timer chip to close a 110 relay- board power supply is going to deal better w/ flux than the arc, so it might be that your hot-starts aren't tripping all the way.

You in Cali?

'cause if you are, your voltage gets all kinds of wacky this time of year... people and their air conditioners.


I don't know, man... IANAEE ( I am not an electrical engineer), but it seems worth investigation.
