Bosch Range Electrode / surface-burner spark electrode 00631633, Replaces 631633

6.35 mm top-mount electrode (G8) used to generate the spark that ignites a gas surface burner.

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• No visible spark at the burner electrode
• Weak or misdirected spark
• Burner requires repeated ignition attempts
• Clicking continues while the burner fails to light
• Visible cracking or tracking through the electrode’s ceramic insulator

Check Before Replacing

• With the appliance cool, gas supply off, and electrical power disconnected, visually inspect the electrode for cracks, carbon tracking, grease, food residue, or damage.
• After restoring power and gas, observe from a safe distance whether a spark is present at the electrode tip when the burner control is turned to ignite; do not touch the electrode or exposed wiring.
• Confirm the burner cap and burner head are correctly seated and clean, since misalignment or contamination can prevent the spark from reaching the gas-air mixture.
• If the electrode sparks but the burner does not ignite, check whether other burners operate normally; this helps distinguish a burner/electrode issue from a broader ignition or gas-supply problem without establishing a diagnosis.
