Dacor Microwave light bulb not working

Is your Dacor microwave light not working, or is the microwave light bulb burned out? The most likely cause is a failed Dacor microwave light bulb, so replace the bulb before testing other parts. Some Dacor models use a halogen lamp, which you can test for electrical continuity with a multimeter or install in an identical socket. If the lamp and light socket are working, inspect the wiring and test the main control board to confirm it sends the correct voltage to the socket. A defective door switch can also keep the light from turning on because it does not tell the control board whether the door is open or closed. If needed, test each door switch and micro switch for continuity. A less common cause is a failed control board. Enter your model number to find the exact Dacor microwave light bulb, halogen lamp, socket, door switch, micro switch, or control board for your appliance. If testing requires opening the outer cabinet, unplug the microwave first. The high-voltage capacitor can store a lethal charge even after unplugging and must be properly discharged before interior work. If you are not familiar with capacitor discharge procedures, have a qualified technician handle the repair.

Before replacing the control, check the light bulbs, sockets, and wiring.

04 - Dacor 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.
