Weber 64136 Spirit 500 Liquid Propane Gas Manifold

What Problem This Part Solves

The manifold assembly controls the flow of propane from the fuel source to the burner and allows the burner flame to be adjusted through the control knob. Because it contains precision-machined gas passages and internal valve components, years of use, corrosion, grease accumulation, or physical damage can eventually affect its performance.

Common symptoms of a failing manifold include:

• Gas leaks around the valve
• Burner won't light properly
• Uneven flame height
• Burner cannot be adjusted
• Stiff or seized control valve
• Inconsistent cooking temperatures
• Poor burner performance
• Propane odor near the control panel

Replacing the damaged manifold with the genuine Weber 64136 restores safe propane delivery, smooth burner adjustment, and reliable grilling performance.
