Have a blank panel board have sent in for repair thought it was out. Have re-installed and still have a blank board. Checked to see if power was going to transformer put meter across both red wires and nothing. At a loss
Answer Steve, you will need to check the control panel thermal fuse 4456654 for a "closed" circuit, and voltage across connector P19 pins 1(black) and pin 3(white) for 120 VAC into the ERC/Clock and out to the transformer (120 VAC across the red wires, and 20 VAC out of the transformer to the control, across the two blue wires).
No lights on the control panel. The oven will come for about 1 minute and then goes off. The transformer has 20+ volts.
If the control panel is going out and the transformer is good then the control board is faulty and would need to be replaced.
