When your Bosch range vent hood lights are not working, start with the light assembly, especially if the bulb is not sold separately for your model. Next, replace the range hood light bulb, since a burned-out bulb is the most common cause. Bosch range vent hoods that use halogen lamps may have one or more burned-out halogen lamp bulbs. Because a failed lamp can be difficult to identify visually, test each one for continuity with a multimeter or replace the bulbs. If a new bulb does not work, test the range hood light socket for incoming power. A socket that has power but does not light the bulb is defective and should be replaced. The light switch is another likely cause. Test it for continuity and replace it if the circuit is open. Finally, test the push button switch, which can also prevent the vent hood light from turning on. Disconnect power before testing or replacing parts, and enter your Bosch range vent hood model number to find the exact replacement light assembly, bulb, halogen lamp, socket, light switch, or push button switch for your appliance.

One or more of the halogen lamp bulbs may be burned out. Since it’s very difficult to visually determine if any of the halogen lamps have burned out, use a multimeter to test them for continuity. Alternatively, you can just try replacing the bulbs.
To determine if the light socket is defective, use a multimeter to test the incoming power to the socket. If the light socket has power, but the light bulb isn’t working, replace the light socket.
To determine if the light switch is defective, use a multimeter to test the switch for continuity. If the light switch does not have continuity, replace it.
To determine if the push button switch is defective, use a multimeter to test the switch for continuity. If the push button switch does not have continuity, replace it
