Crosley Microwave light bulb not working

If your Crosley microwave light is not working, the light bulb itself is the most likely cause and may simply be burned out. Replace the microwave light bulb before testing other parts. If your model uses a halogen lamp, test it with a multimeter for continuity or install it in an identical socket. If the bulb, socket, and wiring are in good condition, the main control board may not be sending the correct voltage to the light socket. A defective door switch can also prevent the cavity light from turning on or stop the light-control button from working, so test the primary, secondary, or monitor switch for continuity. A control board or micro switch can cause the same symptom, although these are less common. Enter your Crosley microwave model number to find the exact replacement light bulb, halogen lamp, door switch, micro switch, or control board for your appliance. Any repair that requires removing the outer cabinet must be handled carefully because the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. Properly discharge the capacitor before interior work, or hire a qualified technician if you are not familiar with capacitor discharge procedures.

03 - Crosley Microwave Main Control Board

Before replacing the control, 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.

04 - Crosley Microwave Door Switch

A defective door switch may not signal the control board that the door is open or closed which may prevent the microwave light from turning on or prevent the button that controls the light from functioning. To determine if any of the door switches are defective, use a multimeter to test each of the switches for continuity. If any of the door switches do not have continuity, the switch or switches should be replaced.

05 - Crosley Microwave 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.

06 - Crosley Microwave Micro Switch

A defective micro switch may not signal the control board that the door is open or closed which may prevent the microwave light from turning on or prevent the button that controls the light from functioning. To determine if any of the micro switches are defective, use a multimeter to test each of the switches for continuity. If any of the micro switches do not have continuity, the switch or switches should be replaced.
