Parts for Thermador SGC304RW: Component Parts

Used to hold down the jet holder assembly.

This jet holder assembly secures the burner orifice and delivers the correct-sized gas jet for a 12,500 BTU natural gas burner, helping restore proper flame size and consistent ignition. What it does:

• Holds the burner orifice in the correct position so gas flows through the proper jet
• Provides the factory-sized orifice for a 12,500 BTU natural gas burner to maintain intended flame height
• Helps correct weak or uneven flames caused by a missing, damaged, or incorrect jet holder
• Supports reliable ignition when installed and aligned properly

• One jet holder assembly (blue) with the 12,500 BTU natural gas orifice installed

• Turn off the appliance and shut off the gas supply before starting any work
• Only install the exact orifice variant specified for your appliance; confirm color/marking and orientation before tightening
• Re-check all gas fittings and perform a leak test after installation

The Jet Holder with Nut is an OEM part for Bosch ranges and cooktops. It holds precisely machined jets that control gas flow from each burner valve.

Causes may be wear and deterioration from prolonged heating exposure. Physical impacts or damage accumulation over time could also compromise the jet holder.

Symptoms of a bad jet holder can include:

• Inability to adjust or maintain proper flame stability and heat output
• Irregular or uneven flame patterns between surface burners
• Potential gas leaks observed at jet connections

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

This is a replacement gas tubing assembly for your gas range that routes fuel safely between the valve and burner manifold. Replacing damaged tubing restores proper gas flow and helps eliminate leaks or ignition problems. What it does

• Routes gas from the range's valve to the burner manifold or secondary fittings
• Restores proper fuel flow when old tubing is cracked, corroded, or pinched
• Addresses common symptoms like a gas smell near the appliance, burners that won't light, or visible tubing damage
• Serves as a direct-fit OEM-style replacement when the original tubing is worn or leaking

• One gas tubing assembly

• Turn off the appliance gas supply and power before inspecting or replacing tubing
• Only install with compatible fittings and thread sealant rated for gas connections; follow manufacturer torque specs
• After installation, perform a certified gas-leak test and check all burner operations

The Spark Switch is an OEM part for Bosch ranges. This part ignites the burners by sending a signal to the spark module, which then produces the spark needed to ignite the gas.  

Causes of a bad spark switch can include wear and tear from regular use, damage from spills or cleaning agents, or electrical issues.  

Symptoms of a bad spark switch include:

• Burners not igniting
  Continuous clicking even after the knob is turned off
  No spark when attempting to ignite the burner
  The cooktop not producing a flame

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

The Spark Module is an OEM part Bosch ranges and cooktops. This electronic part generates the high-voltage spark needed to reliably ignite the gas burners with the push of a button.

Causes can be issues like component failure over the thousands of ignitions it facilitates. Water ingress could also potentially cause problems. 

Symptoms of a bad spark module include:

• Unreliable or intermittent burner ignition requiring multiple ignition button presses
• One or more burners that will not ignite at all
• Occasionally flashing or error codes relating to ignition issues

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

This part has been discontinued by the manufacturer and is no longer available.
