XPARTCO 00631633 Range Surface Burner Igniter Electrode
The XPARTCO 00631633 is an aftermarket replacement gas range surface burner igniter electrode (also called a spark electrode) compatible with select Bosch, Thermador, and Gaggenau gas ranges and cooktops in the HDI, HGI, NGM, NGMP, HDIP, and HGIP series. The surface burner igniter electrode is the ceramic-tipped spark generator located at each gas burner position on the cooktop. When the burner is turned on, the ignition system sends a high-voltage pulse to the electrode, which generates a spark across the ceramic tip to ignite the gas flowing from the burner. When the electrode cracks, chips, or becomes contaminated with grease or food residue, the burner may fail to light, click continuously without igniting, or spark intermittently.
This replacement electrode is constructed from high-quality ceramic and metal — the ceramic insulator body withstands the thermal cycling of repeated ignition, while the metal spark tip maintains reliable spark gap geometry over time. Sold individually — one electrode per order. It directly replaces AP5950372, 4162041, and PS10057850. Because a gas range typically has four or more burners with individual electrodes, compare your existing electrode's dimensions and mounting configuration before ordering to ensure a correct fit. Installs in minutes — no tools required in most cases.

Ceramic and metal construction. Sold individually — one electrode per order. Compatible with Bosch HDI, HGI, NGM, NGMP, HDIP, HGIP series. Replaces AP5950372, 4162041, PS10057850. Compare dimensions to your original before ordering — each burner position uses the same electrode style on compatible models.
Common Problems This Part Fixes
Gas burner will not light when the knob is turned
Burner clicks repeatedly without igniting the gas
Burner sparks intermittently — fires once or twice but does not sustain ignition
Igniter clicks continuously even when the burner knob is in the off position
One burner not lighting while other burners on the same range work normally
Electrode tip visibly cracked, chipped, or heavily contaminated with baked-on grease
Weak or inconsistent spark — arc not reaching the burner port reliably

Installation Notes
⚠️ Gas Appliance Safety Warning This part is used in gas ranges. Always turn off the gas supply at the shutoff valve and unplug the range from the electrical outlet before beginning any repair. If you smell gas at any point during or after installation, leave the area immediately and contact your gas utility provider. If you are not confident working on gas appliances, have this part installed by a qualified appliance technician.
⚠️ Unplug Range and Turn Off Gas Before Starting With the range unplugged and gas supply off, remove the cooktop grates and burner caps to access the burner heads. The igniter electrode is the small ceramic component positioned beside each burner head, held in place by a mounting bracket and screw or a snap-in clip depending on the model. Disconnect the single wire connector from the old electrode. Remove the mounting screw and lift the old electrode out. Install the new 00631633 electrode in the same position, secure the mounting screw, and reconnect the wire connector. Replace the burner caps and grates. Restore power and gas supply, then test each burner for reliable ignition. If the burner still does not light after replacing the electrode, inspect the igniter wire and the electronic ignition module. Tools needed: Phillips or Torx screwdriver (for mounting bracket on some models); no tools needed on models with snap-in electrodes.
Frequently Asked Questions
What does the surface burner igniter electrode do?
The igniter electrode is the component that creates the spark to light each gas burner. When you turn a burner knob past the "lite" position, the range's electronic ignition module sends a series of high-voltage pulses through the igniter wiring to the electrode at that burner. The electrode generates a visible spark across its ceramic tip to the grounded burner cap or burner head, and that spark ignites the gas flowing from the burner ports. Each burner position has its own dedicated electrode — failure of one electrode affects only that burner, while other burners on the same range continue to work normally.
My burner clicks constantly even when turned off — is it the electrode?
Constant clicking when a burner is in the off position is almost always caused by moisture or food residue in the igniter system rather than a failed electrode. When liquid boilover or steam gets into the burner cap area or electrode housing, it can cause the ignition module to fire continuously. Remove the burner cap and grate from the affected burner and allow everything to dry thoroughly — an hour in a warm oven (electric only, turned off) can help. Wipe the electrode tip clean with a dry cloth. If clicking persists after the components are completely dry and clean, the electrode or the ignition module may have been damaged by the moisture and needs replacement.
How many electrodes do I need for my Bosch range?
Most Bosch gas ranges have four surface burners, each with its own dedicated igniter electrode — so a full cooktop replacement typically requires four electrodes. This listing is for one electrode. If only one burner is not lighting, you likely only need one replacement. If multiple burners are failing, order one electrode for each affected burner. Because the electrodes on compatible Bosch models use the same part number across all burner positions, one order of multiple quantities covers all positions.
Can I clean the electrode instead of replacing it?
Yes — a contaminated or greasy electrode can often be cleaned successfully rather than replaced. Remove the electrode from the burner area and gently clean the ceramic tip and metal contact with a dry cloth or a soft toothbrush. Do not use water or liquid cleaners directly on the electrode — moisture in the ceramic can cause persistent clicking. If the ceramic body is cracked or the metal tip is corroded or missing, replacement is required. If the ceramic is intact and clean but the spark is still weak or absent, the electrode's spark gap geometry may have changed from thermal expansion and a replacement is the better fix.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Bosch OEM part, but is manufactured from high-quality ceramic and metal to match the dimensions and spark performance of the original 00631633 igniter electrode.
