Parts for Thermador SB2B: 06 - Inner Burner Box Parts

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 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.

This is a cooktop burner igniter OEM replacement part for Bosch cooktops and ranges and is sold as an individual part. This part creates a spark that ignites the burner within your cooktop or stovetop and is made of a combination of metal and ceramic.

Causes of a bad ignition plug can include issues with the electronic module, worn electrodes that no longer spark reliably, or damaged wiring.

Symptoms of a bad ignition plug include:

• Gas burners that will not light or remain lit
• Delayed ignition of one or more burners
• Intermittent or no sparking from the ignition plug

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

The Igniter Mounting Clip is an OEM part for Bosch ranges. It secures the igniter to the range top, ensuring it is properly aligned and stable for optimal ignition performance. The surface igniter is crucial for the ignition of gas burners, facilitating an immediate and safe flame to cook with.

Over time, the Igniter Mounting Clip can succumb to various forms of wear and tear, including corrosion from exposure to moisture, degradation from frequent heating cycles, or physical damage during cleaning or maintenance activities. 

Symptoms of a compromised Igniter Mounting Clip include:

• The surface igniter becoming loose or dislodged
• Difficulty in igniting the burner or uneven flames
• Noisy or irregular ignition sounds
• Visible signs of damage or corrosion on the clip

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

Used to hold down the jet holder assembly.

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 1/4-inch gas supply tube routes fuel between internal components of the appliance, such as the regulator/manifold and valve or burner assembly. Replacing a damaged line helps restore safe, consistent gas flow and dependable burner operation.

• Carries gas from the regulator/manifold to downstream valve/burner components
• Direct replacement for a kinked, cracked, or corroded tube
• Maintains proper routing and secure, sealed connections inside the unit

• Shut off gas and power; allow the unit to cool and ventilate the area before service
• Support fittings with two wrenches; avoid over-torquing and do not kink the tube
• After installation, check all joints with an approved leak-detection solution—never an open flame

This 1/4-inch gas supply tube routes fuel between internal gas components to deliver a stable, leak-resistant supply to the burner. Replacing a damaged tube helps restore safe operation and consistent burner performance.

• Carries gas between internal components (such as the valve/manifold and burner)
• Maintains a sealed pathway to prevent leaks
• Helps ensure proper ignition and flame size
• Common signs of failure: visible kinks, cracks, or corrosion; weak/no flame; gas odor near the tube

• Shut off gas supply and power before servicing; work in a well-ventilated area
• Match original routing and orientations; avoid kinks and sharp bends
• Tighten fittings to manufacturer guidance; do not overtighten
• Leak-test all joints with approved leak-detection solution and verify burner operation

This rear trim is the exterior trim panel that covers the back edge of the appliance for a finished look and basic protection. It restores a clean appearance and helps keep wiring and components concealed. What it does:

• Covers and protects exposed rear edges and openings
• Hides wiring and component access at the appliance rear
• Restores finished exterior appearance after repairs or replacements
• Reduces drafts and movement-related rattling at the back panel

• Disconnect power and disconnect water before beginning work
• Require removing the rear access panel or nearby panels to fit; basic hand tools typically needed
• Handle carefully — edges can be sharp and trim can be fragile
• Secure fasteners to prevent loosening or vibration

This gas pressure regulator controls and stabilizes incoming supply pressure to the appliance manifold, helping ensure consistent burner flames and reliable ignition. Replace if the original regulator is sticking or no longer maintaining correct pressure.

• Regulates incoming gas to the appliance's rated manifold pressure
• Helps maintain even flame height and proper combustion
• Supports reliable burner ignition and reduces flame-out from pressure swings
• Common symptoms include weak or uneven flames, yellow tipping, burners not lighting or not staying lit, or flames that are too high

• Disconnect electrical power and shut off the gas supply before servicing
• Observe the flow-direction arrow; install with outlet toward the appliance manifold
• Use approved gas-rated thread sealant on male threads only and leak-test all joints with a non-corrosive solution after installation
