Parts for Thermador STAR BURNER: 04 - Star Burner Parts

This Pro-Star burner head is the top-side gas burner component that directs and shapes the cooktop flame for stable cooking. It replaces a damaged or worn burner head to restore proper flame pattern and heat delivery. What it does:

• Directs gas to produce an even, controlled burner flame for cookware
• Restores correct flame pattern when the burner is producing uneven or weak flames
• Replaces corroded, cracked, or warped burner heads that interfere with ignition
• Helps reduce burner chatter or flickering caused by damaged head ports

• One Pro-Star burner head (single)

• Turn off the gas supply and unplug the appliance before servicing
• Remove grates and burner caps, then lift out old head and set new head into position
• Ensure the head seats flat and ports align; do not force or overtighten

The Spark Electrode is an OEM part for Bosch gas cooktops and ranges. It generates the electrical ignition required to light the gas burners via spark generation.

Causes of a bad spark electrode can include deterioration from continuous heating and cooling exposure during use. Physical damage or failure of insulation surrounding the electrode may also lead to malfunction over time.

Symptoms of a bad spark electrode include:

• Inability to reliably light one or more gas burners
• Delayed or multiple ignition attempts needed for burners to light
• A surface burner that will not ignite at all

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

Replacement 1-14 nut for star-style cooktop burners. Secures the burner head and cap to keep the burner centered, helping restore consistent flame position and stable cooking performance. What it does:

• Secures the star-shaped burner head to the stove so the cap stays properly seated.
• Keeps the burner aligned to help maintain even flame distribution and reliable ignition.
• Prevents burner wobble or movement that can cause uneven heating or noisy operation.

• Turn off gas supply and unplug or shut power to the appliance before servicing.
• Use the correct-sized wrench; start threading by hand to avoid cross-threading.
• Tighten snugly but avoid overtightening to prevent thread damage—refer to the service manual for torque guidance.
• After installation, ensure the burner head and cap are seated and aligned before restoring gas/power.

This spark electrode assembly produces the ignition spark for a gas burner. Replacing a worn igniter pin helps restore quick, consistent lighting and reduce nuisance clicking or misfires at the affected burner. What it does

• Generates a high-voltage spark at the burner to ignite gas when you turn the knob
• Helps address a burner that won't light or only lights intermittently
• Useful when spark is weak/absent at one burner or the ceramic insulator is cracked
• Proper alignment and clean burner surfaces support reliable ignition

• One igniter pin with mounting base

• Disconnect electrical power and shut off gas; allow the appliance to cool completely
• Remove burner cap/head and top or trim as needed to access the electrode
• Connect the spark lead and seat the base securely; avoid stressing or cracking the ceramic
• Reassemble, verify spark at the tip, and test ignition at low and high settings
