Thermador Microwave Oven Combo CM302UB Parts

The Bulb is an OEM part for Bosch ovens. This component provides illumination inside the oven, allowing you to easily monitor the cooking process without opening the door and losing heat.

Causes of a bad bulb can include filament burnout due to extended use, electrical issues that cause power surges, or physical damage from accidental impacts. 

Symptoms of a bad bulb include:

• The oven light not turning on
• Flickering light inside the oven
• Dim or uneven lighting
• The bulb appearing visibly damaged or burnt out

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.
