Parts for Thermador PRSG304S: Burner Section Parts

The Spark Ignition Switch is an OEM part for Bosch ranges and cooktops. It controls the ignition of surface burner flames by emitting an electrical spark when activated.

Causes of a bad switch can be general wear and fatigue over thousands of start cycles. Exposure to moisture, dust or metal debris could also damage electrical components internally.

Symptoms of a bad spark ignition switch include:

• Burners failing to light even when valves are turned on
• Intermittent or irregular lighting of some burners
• No electrical sparks emitted from the ignition electrode

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

Controls gas supply pressure to burner manifold. Replace if regulator is cracked, sticking, or no longer maintaining correct pressure for consistent flames.

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.

Burner won't light or has no gas flow? This top burner valve controls gas to individual burners. Moderate DIY repair with basic tools needed.

1/4" gas supply tubing connects your range's gas line to the valve. Replace when damaged, cracked, leaking, or during valve service for safe operation.

This flexible gas supply tube connects your range's gas valve to the burner assemblies, safely delivering natural gas or propane for cooking. It's designed to withstand the heat and vibration of normal range operation while maintaining a secure gas connection. Replace it if you smell gas near your range, notice corrosion or cracking on the tube, or if burner flames are uneven or won't light properly.

Gas supply tube connects gas line to range burners. Replace if cracked, kinked, damaged, or leaking. Installs between supply valve and burner assembly.

Jet holder securely houses the orifice assembly on gas range burners. Replace if cracked, corroded, or heat-damaged. Ensures proper gas flow and ignition.

This is a duct assembly used in a range or oven to direct airflow for ventilation or cooling of internal components. It channels hot air or combustion byproducts away from sensitive parts to ensure safe and efficient operation. Replace this duct if it is cracked, disconnected, or if you notice unusual heat buildup, poor ventilation, or error codes related to overheating.

Used to hold down the jet holder assembly.

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.

This igniter creates the spark needed to light gas burners on your range cooktop. It generates an electric arc that ignites the gas flow when you turn the burner control knob. Replace this part if burners won't light, take multiple attempts to ignite, or produce weak clicking sounds without lighting.

Venturi tube for gas ranges and cooktops. Mixes gas and air for proper burner combustion. Replace if cracked, corroded, or threads are damaged.

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 Grate Foot Kit is an OEM part for Bosch ranges. This kit includes the small rubber feet that attach to the bottom of the range grates, providing stability and preventing the grates from scratching the range surface.

Over time, the grate feet can wear out or become damaged due to exposure to high temperatures, regular cleaning, or accidental impact. Missing or worn-out feet can cause the grates to sit unevenly or scratch the range surface.

Symptoms of a bad grate foot kit include:

• The range grates sitting unevenly or wobbling
• Scratches or damage on the range surface
• Grates sliding or shifting during cooking
• Missing or visibly worn-out rubber feet

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

The gas supply tube delivers gas from the main line to the range burners and is located behind or underneath the unit. Replace if you smell gas, notice uneven flame patterns, or if the tube shows signs of corrosion or damage during inspection.
