Main Control Board/Display
The control board signals each oven component based on commands sent from the HMI electronic
board that were selected by the operator.
The Power Module board has connected a current sensor which measures the amp draw of the
microwave circuit through the brown CT wire looping through it. The current sensor is what
determines if the microwave circuit is working correctly by communicating the registered amp draw
to the board.
The current sensor is connected around the wire number 36 of the power distribution bar on the right
side of the oven.
