The Burner Cap is an OEM part for Bosch Ranges. This part fits atop the burner assembly, playing a vital role in controlling and diffusing the flame for cooking.

A common issue with a malfunctioning or worn-out Burner Cap involves deterioration over time due to exposure to heat, grease, or cleaning agents. Damage or deformation to the cap can disrupt the flame pattern, leading to inefficient cooking or inconsistent heat distribution.

Symptoms of a defective Burner Cap may include:

• Uneven or erratic flames during burner operation
• Inadequate heat output or difficulties in achieving desired temperatures
• Visible signs of damage or wear on the burner cap's surface

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

This burner cap covers the gas burner head to help direct flame for even cooking and protect the burner assembly from spills and debris. Simple replacement restores proper flame shape and helps maintain safe operation. What it does:

• Centers and shields the burner head so flames distribute evenly across cookware
• Helps prevent food and liquid from entering the burner ports and clogging them
• Supports stable ignition by keeping the flame pattern consistent
• Can help reduce irregular or uneven flame appearance when damaged or misaligned

• Turn off gas supply and let cooktop cool completely before handling
• Lift off the old cap, clean the burner head and surrounding area, then set the new cap in place so it seats flat and centered
• No special tools required; ensure the cap is not rocking and does not block ignition ports
• If ignition problems persist after replacement, inspect burner ports and igniter for debris or damage
