The stall fault went away so far when I extended the stall timer. but now I get a Door Zone Aux failed off message. I just replaced both DZ relays and the DZ input chip on the 1038 board and also replaced the DZA output on the Selector driver board. We'll se if that works. if not Im gonna open the valve and start from square one on it. The valve has been running fine for years so I would assume it would be the screen clogged but you never know.
