went on a call last night for a no hot water, got there and its a polaris. board was replaced not that long ago, ignitor wouldnt fire. disconnected it from the board and was able to pull 120ohms from it. called another tech to get an idea of where to go from there and was told board is no good. is there any other way to confirm board is bad and its not something else. Im going back to this job later today, sitting here thinking about it, the board has to be giving the ignitor power, so I shouldnt get voltage from the board if its bad right? would it be from both terminals? and does anyone know if its just 120 or should it be a different voltage?
