• Restores correct mounting for the motor, suspension and rear panels to reduce vibration and noise.
• Helps stop misalignment-related issues that can cause rubbing or excess movement.
• Used when the existing floor/rear chassis is bent, corroded, or damaged and causing leaks or improper fit.

• One chassis assembly as shown.

• Disconnect power and water supply before starting repairs; follow all safety procedures.
• Basic mechanical skills and common hand tools required; effort may include removing trim, panels and mounted components.
• Retain and reuse any original fasteners or brackets unless replacement fasteners are specifically required.

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.

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.

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

This valve access cover protects the appliance valve area from debris and accidental contact while allowing service access when needed. It keeps wiring and valve components shielded and helps maintain safe, reliable operation. What it does:

• Shields the water/valve area and nearby wiring from dust and foreign objects
• Provides an access point for servicing or replacing the valve without removing larger panels
• Helps prevent accidental contact with valve components during normal use
• Reduces risk of minor water intrusion reaching valve components

• One valve access cover

• Disconnect power and shut off the water supply before servicing
• Remove any retaining screws or clips, align cover tabs, and reinstall fasteners securely
• Inspect surrounding seals and mounting points; replace cover if cracked or warped

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.

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 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:

• Channels natural gas/LP from the household supply to the appliance valve
• Replaces cracked, corroded, or bent tubing that can cause leaks
• Helps stop symptoms like a persistent gas smell, failure to ignite, or intermittent burner operation
• Works with the appliance's inlet and control valve fittings to maintain proper gas flow

• Turn off the gas supply and electrical power before starting work
• Use approved fittings, thread sealant rated for gas, and test all connections for leaks after installation
• Do not modify or reuse damaged tubing; replace with exact-fit parts

This rear component cover protects and conceals a product's internal electronics and wiring, keeping components secure and reducing exposure to dust and debris. It restores the unit's enclosure for safe, reliable operation. What it does:

• Covers and shields internal control components and wiring from debris
• Helps prevent accidental contact with live parts and sharp edges
• Reduces vibration-related noise by securing loose components
• Visible damage or a missing cover can lead to exposed parts or rattling

• Always disconnect power to the appliance before beginning any repair
• Some models secure this cover with clips and/or screws; keep fasteners for reassembly
• Handle edges carefully to avoid cuts and prevent damage to wiring or connectors
• Follow the OEM service manual or exploded view for correct removal and reinstallation

This is a gas valve assembly, also referred to as a safety valve, that is used on an oven. It supplies gas for the bake and the broil burners of the oven.When this part is faulty, the user may notice that the broiler or the bake functions are not working properly. Basically, the oven will not heat in any way. Some users also report a gas smell coming from the unit when this part has gone bad. If this is the case, shut off the gas immediately until this part can be replaced. Make sure to disconnect the range and shut off the gas before replacing this part. Wear work gloves during this process.This gas valve assembly is sold individually. It is sourced straight from the manufacturer itself. This particular gas valve assembly is compatible with gas ovens that are manufactured by Bosch, including the Thermador and Gaggenau brands.
