Thermador Cooktop Burner & Related Parts

The Venturi Gas Tube is an OEM replacement part for Bosch gas cooktop ranges. Its primary function is to ensure an optimal gas/air mixture for consistent and efficient burner combustion, thereby enhancing the overall performance of the cooktop.

Causes involve normal wear of internal components from continuous heating and cooling cycles. Corrosion damage may also disrupt the venturi tube over time.

Symptoms of a faulty venturi gas tube include:

• Unstable or hard-to-control flame levels
• Potential issues shifting burner flames out of their intended position
• Safety risks including carbon monoxide from improper fuel/air balance

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

The Burner Cap is an OEM part for Bosch gas cooktops. This small black burner cap safely contains the flame underneath to concentrate heat efficiently for precise cooktop control. Reliable burner caps are crucial for safety, performance, and aesthetics.

Causes of a bad burner cap can include warping or cracking from continuous exposure to high heat over the long run, as well as surface scratching or punctures.

Symptoms of a faulty cap include:

• Flames escaping beyond cap and licking up sides of cookware
• Visible damage or deterioration on cap surfaces
• Inability to adjust flame height as intended
• Burners no longer heating or shutting off properly

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

The Burner Head and Cap Assembly is an OEM part for Bosch ranges and cooktops. It contains the burner itself along with its protective cover.

Cracks or misshapen portions disrupt flame stability leading to inconsistent results.

Symptoms of a failed assembly include:

• Irregular or overly high flames from damage exposing gas jets
• Difficulty igniting or flames extinguishing prematurely
• Singed pans lacking the protection of an intact cap

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

The Burner Cap Assembly "C" Matte Blk is an OEM part for Bosch gas cooktops. As the rounded covering fitted over individual burners, it safely contains flames underneath cookware. Maintaining proper cap placement is vital for heating performance and safety compliance standards.

Causes of a bad burner cap assembly can include cracks or punctures from sustained high temperature cycling that compromise its insulating barrier. Over time, surface imperfections like scratches also diminish durability against consistent heat exposure.

Symptoms of faulty caps are:

• Flames improperly escaping from under pan edges
• Visible damage present on cap surfaces
• Inconsistent flame height adjustment or shut-off
• Excessive heat concentration in burnered area

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

This burner base supports the cooktop burner assembly and helps position the burner cap for a consistent flame. Replace a damaged or warped base to restore proper burner alignment and reliable ignition. What it does

• Holds the burner head and cap in the correct position for even flame distribution.
• Stabilizes the burner assembly so the ignition electrode can spark reliably.
• Helps prevent burner cap wobble or misalignment that causes uneven heating.
• Can resolve symptoms like burners that light intermittently or produce an irregular flame pattern.

• One burner base.

• Disconnect power and shut off the gas supply before beginning service.
• Remove burner grates and caps; replace base using basic hand tools—do not force parts.
• Inspect surrounding gaskets and the ignition electrode for damage; clean any debris before reassembly.

The Burner Cap Assembly is an OEM part for Bosch ranges and cooktops. It refers to the rounded caps placed over each burner to contain and direct flames safely.  

Causes of a bad burner cap assembly can include warping, cracks or punctures from consistent high heat that allow flames to escape improperly. Surface scratches likewise compromise insulation and durability over time.

Symptoms of damaged or faulty caps are:

• Excessive flames licking up beyond cap borders
• Scratches or cracks visible on hot surfaces
• Difficulty adjusting flame height precisely
• Burners do not heat evenly or shut off completely

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

This burner base supports the cooktop's burner cap and directs flame for even heating. It replaces a damaged or warped base to restore stable burner alignment and consistent flame pattern. What it does:

• Holds the burner cap in place and centers the gas flame
• Channels gas flow for proper burner operation
• Helps prevent wobbling or uneven heating from a warped base
• Commonly replaced when the base is cracked, corroded, or bent

• One burner base (B)

• Turn off gas supply and power to the appliance before servicing
• Remove surrounding burner components and reassemble in reverse order
• Inspect nearby seals and burner ports for damage; replace if necessary

This burner cap assembly covers and protects the gas burner head and helps shape the flame for even cooking. It replaces a damaged or missing cap to restore proper burner appearance and flame pattern on compatible cooktops. What it does:

• Centers and shields the burner head to promote an even flame distribution during use
• Replaces cracked, warped, or missing caps that can cause uneven heating or unstable flames
• Helps maintain correct burner alignment for reliable ignition
• Restores finished appearance around the burner for safe, proper operation

• One black burner cap assembly

• Turn off gas supply and power to the appliance before servicing
• Allow the cooktop to cool fully; handle with care to avoid scratching or chipping
• Seat the cap squarely on the burner head—no tools typically required

The Jet Holder is an OEM part for Bosch ranges. It is responsible for securely housing components that generate flames and distribute heat across the cooktop surface. The jet holder ensures proper airflow and fuel ignition during operation.

Symptoms of a bad jet holder include:

• Unsteady or unstable flames during cooking  
• Flames that cross-ignite between burners
• Inefficient heat transfer causing slow cooking times
• Loose, damaged, or missing jet holder components

Causes of a bad jet holder can include cracks developing from excessive heat cycling or debris buildup restricting gas/airflow. Mineral deposits may also cause fittings to warp and lead to improper alignment. 

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

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
