I have tested every component and all test good. The top coil gets 90 vdc, the ignitor glows, the flame sensor closes and gets 120 vac but the bottom coil never receives 90vdc. Should I assume that I need a new control board or a new gas valve? I am unsure if board sends seperate 90 vdc or if the coils are bad the voltage will not transfer to the other. I sent a pm to Lg John but not sure if I will receive a response because he has been inactive for a while. Please Help!
