This part is a genuine OEM gas valve made for use with gas-powered ranges. The gas valve ensures that gas can enter the appliance so that the burners can light. If the gas valve is faulty in any way, such as being bent, dented, detached, or otherwise rendered ineffective, it could prevent the burners from lighting or may weaken the strength of the flame. Before replacing the gas valve, put on work gloves to prevent injuries to the hands and disconnect the range from the power and gas sources.This part is manufactured by Bosch and has been sourced directly from the manufacturer. It is sold individually. This gas valve is manufactured from high-quality, durable, non-corrosive metal and other materials. It is an authentic replacement part and thus is compatible with ranges manufactured by Bosch, Thermador, and Gaggenau.

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.

• 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

This 1/4" gas supply tubing connects the appliance's gas line to the valve, providing a secure path for fuel so the unit can ignite and operate safely. Use when tubing is damaged, leaking, or replaced during valve service. What it does:

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. 
 

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.
