Common solutions for: Microwave light bulb not working
01 - Control Board
A microwave light bulb not working could be caused by a defective control board, although this is rarely the case. Before replacing the control board, check the light bulbs, sockets, and wiring. If these parts seem to be working properly, test the control board with a multimeter to determine if it sending the correct voltage to the light bulb socket. If the control board is not sending enough voltage to the light bulb socket, replace the control board.
