The Gas Burner Seal is an OEM part for Bosch cooktops and ranges. This component sits between the burner and the cooktop surface, providing a seal that prevents gas leaks and ensures efficient burner operation. The seal helps maintain proper gas flow and supports the stability of the burner during cooking. You should replace the gas burner seal if it becomes damaged or deteriorates. Over time, exposure to high temperatures, food spills, and regular cleaning can cause the seal to wear out or crack, leading to potential gas leaks and reduced burner efficiency. Symptoms of a bad gas burner seal include: Visible cracks or damage to the seal Gas smell near the burner area Inefficient or uneven burner flames This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.00189317 (AP2821612) replaces 1013973, 189317, 20-02-018-01, 411545, AH3440540, EA3440540, PS3440540, PS8698434.
