I have a customer with an Ecomatic SWG that was working find a few weeks ago, but has stopped initializing. There is power to the head unit, and the two green lights are on, but it never counts up. When I turn the knob, it displays the output setting for a little while, but then the display goes back to blank. Before I tell this customer they need to replace the whole SWG, I wanted to see if anybody had any suggestions.
