I have a Mt Vernon AE the problem is that I have 6 dashes on the wall control. Also when I plug the stove in the auto clean doesn't operate. I've checked the wall control wires to the stove all good. Power supply checks out, the micro switch on auto clean is in the closed position, tried swapping the wall control, control board and power supply still same thing. Checked door switch and hopper switch. 121 volts at the wall correct polarity and grounded. any ideas????
