Weber 64427 GENESIS Ignition Switch Button Wire Assembly

What Problem This Part Solves

The electronic ignition system on a Weber Genesis grill depends on properly connected wiring to activate the ignition components. Over time, wiring may become damaged, disconnected, or worn from heat exposure, moisture, or regular grill use.

Common symptoms of faulty ignition wiring include:

• Ignition system not activating when the button is pressed

• Intermittent ignition operation

• Loose or disconnected electrical connections

• Damaged or deteriorated ignition wiring

• No spark caused by an interrupted electrical connection

• Visible damage to the original wire assembly

Replacing a defective ignition wire assembly with Weber 64427 can help restore proper electrical connections and reliable grill ignition.

Note: Ignition problems may also result from a defective ignition module, switch, electrode, or depleted battery. Inspect the complete ignition system before replacing individual components.
