Bosch Range HBN4820 Parts

This 120V, 40W oven bulb provides interior lighting so you can check cooking progress without opening the oven door. Designed to match OEM fit and heat-resistance for use in many ranges and wall ovens. What it does:

• Replaces a burned or broken oven light to restore interior illumination.
• Helps you see inside the oven without opening the door, reducing heat loss.
• Appropriate for ovens that require a 120V, 40W heat-rated incandescent lamp.
• Common symptoms it fixes: no light when the door is closed, flickering or dim oven light.

• Disconnect power before replacing the bulb to avoid shock—turn off at the breaker or unplug the appliance.
• Allow the old bulb and oven to cool completely before handling.
• Use a cloth or glove when installing to avoid oils from skin shortening bulb life.
• Follow the appliance manual for bulb access.

Toaster light bulb illuminates the toasting chamber. Replace when bulb burns out or flickers. Verify compatibility with your toaster model number.
