02 - Power Supply Board
A microwave light bulb not working could be caused by a defective power supply board, although this is rarely the case. Before replacing the board, check the light bulbs, sockets, and wiring. If these parts seem to be working properly, test the power supply board with a multimeter to determine if it sending the correct voltage to the light bulb socket. If the board is not sending enough voltage to the light bulb socket, replace the board.
