Parts for Bosch NGT935UC/01: Gas Cooktop Parts

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.

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

This gas burner jet holder assembly routes fuel through the orifice to the burner and secures the connection. The red 11,000 BTU version is designated for the right-front or left-rear burner, helping restore proper flame and heat output.

• Positions the jet and routes gas from the manifold to the burner for the specified heat output
• 11,000 BTU, red-coded variant designated for RF/LR burner location
• Provides a stable, serviceable connection between tubing and burner base for a consistent flame
• Symptoms include weak or irregular flame, failure to ignite, or incorrect flame size at the RF/LR burner

• Shut off gas supply and power; allow the appliance to cool before servicing
• Remove grates, burner caps/heads, and any panels needed to access the holder
• Support gas tubing and use two wrenches on fittings to avoid twisting or damage during removal/installation
• After installation, check all joints with an approved leak-detecting solution and verify flame quality

This burner base supports the cooktop burner assembly and helps position the burner cap for a consistent flame. Replace a damaged or warped base to restore proper burner alignment and reliable ignition. What it does

• Holds the burner head and cap in the correct position for even flame distribution.
• Stabilizes the burner assembly so the ignition electrode can spark reliably.
• Helps prevent burner cap wobble or misalignment that causes uneven heating.
• Can resolve symptoms like burners that light intermittently or produce an irregular flame pattern.

• One burner base.

• Disconnect power and shut off the gas supply before beginning service.
• Remove burner grates and caps; replace base using basic hand tools—do not force parts.
• Inspect surrounding gaskets and the ignition electrode for damage; clean any debris before reassembly.

This burner base supports the cooktop's burner cap and directs flame for even heating. It replaces a damaged or warped base to restore stable burner alignment and consistent flame pattern. What it does:

• Holds the burner cap in place and centers the gas flame
• Channels gas flow for proper burner operation
• Helps prevent wobbling or uneven heating from a warped base
• Commonly replaced when the base is cracked, corroded, or bent

• One burner base (B)

• Turn off gas supply and power to the appliance before servicing
• Remove surrounding burner components and reassemble in reverse order
• Inspect nearby seals and burner ports for damage; replace if necessary

This Venturi is an OEM part for Bosch Ranges. It plays a role in supplying air to the burner for proper combustion. Continuous exposure to heat and debris can cause this part to degrade or malfunction.

What Causes a Bad Venturi: 
Exposure to heat and debris from cooking can cause the venturi to deteriorate over time. Blockages or clogs in the venturi can also affect its functionality.

Symptoms of a Bad Venturi:

• Uneven flame or inconsistent burner operation
• Reduced gas flow to the burner
• Burner flame discoloration

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

This is a cooktop burner igniter OEM replacement part for Bosch cooktops and ranges and is sold as an individual part. This part creates a spark that ignites the burner within your cooktop or stovetop and is made of a combination of metal and ceramic.

Causes of a bad ignition plug can include issues with the electronic module, worn electrodes that no longer spark reliably, or damaged wiring.

Symptoms of a bad ignition plug include:

• Gas burners that will not light or remain lit
• Delayed ignition of one or more burners
• Intermittent or no sparking from the ignition plug

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.

The Burner Cap Assembly "C" Matte Blk is an OEM part for Bosch gas cooktops. As the rounded covering fitted over individual burners, it safely contains flames underneath cookware. Maintaining proper cap placement is vital for heating performance and safety compliance standards.

Causes of a bad burner cap assembly can include cracks or punctures from sustained high temperature cycling that compromise its insulating barrier. Over time, surface imperfections like scratches also diminish durability against consistent heat exposure.

Symptoms of faulty caps are:

• Flames improperly escaping from under pan edges
• Visible damage present on cap surfaces
• Inconsistent flame height adjustment or shut-off
• Excessive heat concentration in burnered area

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

The Burner Cap is an OEM part for Bosch gas cooktops. This small black burner cap safely contains the flame underneath to concentrate heat efficiently for precise cooktop control. Reliable burner caps are crucial for safety, performance, and aesthetics.

Causes of a bad burner cap can include warping or cracking from continuous exposure to high heat over the long run, as well as surface scratching or punctures.

Symptoms of a faulty cap include:

• Flames escaping beyond cap and licking up sides of cookware
• Visible damage or deterioration on cap surfaces
• Inability to adjust flame height as intended
• Burners no longer heating or shutting off properly

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

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.
