Parts for Thermador SGCS456RS: 08 - Gas And Electric Component Parts

Used to hold down the jet holder assembly.

A replacement cover for the left-front potentiometer switch that protects the control shaft and helps maintain knob alignment for reliable temperature adjustments. Fits where the potentiometer's outer trim or cap is cracked, worn, or missing. What it does

• Protects the potentiometer shaft and internal switch from debris and accidental contact
• Helps keep the control knob aligned and seated properly on the shaft
• Restores a finished appearance to the control panel around the left-front control
• Use when the existing cover is cracked, broken, loose, or missing

• Disconnect power to the appliance before beginning any work
• Remove the control knob and any trim or panel pieces as needed to access the potentiometer
• Align the cover over the potentiometer shaft and press or secure per OEM method; handle plastic parts carefully to avoid cracking

Switch, spark assembly restores the ignition switch that creates the spark for gas burners, helping burners light reliably. Replacing this assembly can stop continuous clicking, intermittent sparking, or complete loss of ignition at the burner. What it does:

• Sends spark pulses to the burner electrodes so gas ignites when a control is activated.
• Replaces a failed ignition/spark switch to restore consistent sparking.
• Common repair for symptoms like burners that won't light, intermittent spark, or controls that click but won't ignite.
• Designed as a direct-fit replacement for the factory switch assembly when the part number matches.

• Disconnect electrical power and shut off the gas supply before starting any repair.
• Handle electrodes and ceramic insulators carefully to avoid damage; do not bend or crack the ceramics.
• Match and reconnect wiring to the original terminals; ensure connectors are fully seated before testing.

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.

The Gas Valve Cooktop is an OEM part for Bosch cooktops. This valve is responsible for controlling the flow of gas to the burners on the cooktop. It opens and closes to allow gas to pass through when a burner is turned on and stops the flow of gas when the burner is turned off. 

Causes of a bad gas valve can include wear and tear over time, issues with the valve mechanism such as stuck or blocked components, or damage from exposure to moisture or impact. 

Symptoms of a bad gas valve include:

• Burners not lighting or sparking repeatedly without igniting 
• Uneven or unpredictable burner flame heights
• Burners not getting hot enough for cooking
• Burners that cannot be turned on or off
• Gas leaks around the valve area

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

This gas manifold assembly routes fuel from the range's supply to individual burner valves so burners heat reliably. Replaces a worn or damaged manifold to restore proper gas flow and consistent burner operation. What it does:

• Distributes gas evenly to each cooktop/range burner via the valve ports
• Helps maintain correct burner ignition and consistent flame performance
• Can fail and cause burners not to light, weak flames, or uneven heat
• Works with the appliance's gas valves and regulator to control fuel flow

• Turn off gas supply and electrical power before starting work
• Only install and follow OEM diagram
• Tighten connections to recommended torque and check all fittings for leaks with a soap solution or approved leak detector
• If you smell gas, stop immediately, ventilate the area.

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.
