Ato problems
Thanks for your time!
Im having an issue with my ato. The top off function isnt working - no water being pumped and the top off lights aren't lighting up. I know the unit has power applied to it, b/c i can manually trigger the high level alarm; it lights up and i hear the audible alarm as expected. Hope you can help! |

I assume it is older? The symptoms would only match what I have seen on the older board made before late 2011 and would match to a bad pump or a burned out transistor. If you disconnect the pump and it then lights up, likely a bad pump, otherwise a transistor has burned out on the board.
