Bosch Range HBG73B455 Parts

Seals unused ports in your wall oven to prevent moisture and debris entry. Replace if missing, damaged, or leaking. Verify fit with your model number.

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.
