Disassembly

To remove the Relay Board:

1.  Disconnect power to the oven.

2.  Remove the control panel assembly.                

(See 

Control Panel Removal

.)

3.  Remove the 5 Phillips-head screws. 

4.  Carefully unplug the Relay Board from the

Smart Board

• Location 

(See 

Control Boards and Panel 

Connections

.)

•  Part of the control panel assembly.

•  Performs all logic operations of the microwave. 

Contains all cooking and operating algorithms. 
Uses the relay board to switch loads.

•  All DC voltages generated by the Power Supply 

Board pass through the Smart Board.

•  Re18 VDC between CN103 pins 1 and 5 

(Powers the Smart Board).

Troubleshooting

If the Smart Board is not supplying 5 VDC to the 
VFD, see 

VFD Operating Voltage

.

If the Smart Board is not supplying relay operating 
voltage to the Relay Board, see 

Relay Operating
