Parts for Thermador CGB48RSBU: 20 - Inner Burner Box Parts

This ignition device is the spark module that generates ignition sparks for gas burners and the oven, restoring reliable lighting and safe operation. It fits specific Bosch gas ranges and ovens and replaces a failed spark-generating module. What it does

• Sends high-voltage sparks to burner and oven ignitors so gas will ignite.
• Commonly causes burners or oven to fail to light when the module is defective.
• May produce continuous clicking or no spark at all when failing.
• Works with the range/oven's control and safety systems to sequence ignition.

• Disconnect electrical power and shut off gas supply before starting any work.
• Verify correct part number and orientation; handle with care to avoid damaging connectors or ceramic insulators.
• Inspect wiring and ignitors for damage—replace damaged wiring or ignitors as needed.

This LP burner orifice (#59 drill) meters propane to the burner so your appliance produces a clean, properly sized flame. Use it for LP conversion or to replace a worn or clogged jet that affects burner performance.

• Regulates LP gas flow to the burner for correct flame size and combustion
• Used during LP conversion or when a jet is stripped, damaged, or obstructed
• Incorrect orifice size can cause small or lazy flames, yellow tips, or hard-to-light burners
• Replace if cleaning doesn't restore proper flame or the jet is damaged

• Shut off gas supply and power; allow the appliance to cool before service
• Remove burner parts to access the manifold; match the orifice to the correct burner position
• Start threads by hand and snug gently—do not overtighten soft brass orifices
• After reassembly, leak-test with soapy water and verify flame; final adjustments should follow the unit's service instructions.

This smoker guide/tray assembly guides and supports the smoker tray inside the oven, helping keep smoker pans stable and positioned for even smoking. Replaces a worn or damaged guide to restore proper tray function. What it does:

• Supports and guides the smoker tray so it slides in and out smoothly
• Holds smoker pans or wood chips in the correct position for safe use
• Helps prevent tray wobble, binding, or uneven seating
• Useful when existing guide is bent, cracked, or no longer secures the tray

• High-level replacement; remove power to the appliance before servicing
• Handle edges and mounting points with care to avoid damage
• Verify fit and orientation before final mounting; use existing fasteners unless new hardware is supplied

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 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 radiant surface element heats a cooking zone beneath a ceramic-glass cooktop. Replace a failed element to restore consistent, controllable heat when a burner no longer heats correctly.

• Converts electrical energy into radiant heat for its designated burner zone under the glass top
• Works with the control to cycle heat and maintain the selected temperature
• Typical symptoms when failed: burner will not heat, heats unevenly or only partially, or takes much longer to reach temperature
• Visible damage or hot spots beneath the glass can also indicate a failed element

• Disconnect power at the breaker and allow the cooktop to cool completely
• Lift/remove the cooktop glass to access the element; support the glass to avoid stress or cracks
• Transfer wires from the old element to the new one one-by-one; reuse existing brackets/clips if serviceable
• Seat the element flat and centered; avoid touching the coil surface; reassemble and test operation

Color: black. It measures about 5 inches wide by 21 inches deep.

This bracket securely mounts the spark igniter electrode at the burner, keeping the tip in the correct position for a strong ignition arc. A bent or corroded bracket can cause weak spark, misfires, or a burner that won't light.

• Holds the ignition electrode firmly next to the burner port
• Maintains proper gap and alignment for reliable sparking
• Replaces brackets that are bent, broken, or corroded
• Common symptoms: burner won't ignite or lights intermittently, weak/no visible spark, electrode feels loose or out of position

• Disconnect power and shut off gas; allow the appliance to cool
• Remove grates/caps and panels as needed to access the burner area
• Transfer the existing electrode to the new bracket and secure with the original hardware
• Restore gas and power, then test for proper spark and burner ignition

A hex keps nut (1/4-20) — a hex nut with an integrated locking washer — provides a secure, vibration-resistant fastening for appliance assemblies; stainless steel construction helps resist corrosion in wet or humid areas. What it does:

• Provides a locking nut solution for 1/4-20 bolts and studs; replaces stripped or damaged nuts to restore a secure connection.
• Integrated keps (locking) washer helps prevent loosening from vibration — useful when panels, brackets, or components wobble or rattle.
• Stainless steel material resists rust and corrosion in damp or high-humidity locations.
• Ideal for replacing missing or corroded hardware during repairs or reassembly.

• Use the correct size socket or wrench; tighten to the appliance manufacturer's specified torque where available and avoid overtightening.
• Disconnect power and shut off water supply when working near electrical or plumbing components.
• Inspect mating threads and replace damaged studs or bolts before installing this nut to ensure a proper, long-lasting fit.

Replacement 1/4-20 x 1/2 stainless steel bolt that secures appliance components and restores proper fit. Use when mounting hardware is missing, corroded, or loose to stop rattling and maintain alignment. What it does:

• Fastens panels, brackets and other appliance components to prevent movement and vibration
• Replaces missing, stripped, or corroded bolts that can cause loose parts or noise
• 1/4-20 thread with 1/2" length for applications requiring that fit (per part listing)
• Stainless steel construction helps resist corrosion in humid or wet areas

• Disconnect power and water (if applicable) and remove outer panels before servicing for safety
• Start threads by hand to avoid cross-threading, then tighten with the proper wrench or socket
• Do not overtighten; snug until secure and follow manufacturer torque specs if available

Electrode that produces the ignition spark for gas ovens and ranges, restoring reliable burner lighting. Replace a damaged or worn electrode to stop repeated clicking, weak sparks, or burners that fail to light. What it does:

• Delivers the spark at the burner to ignite gas during startup.
• Common symptom fix: oven/range burners that won't light or that click continuously without producing a flame.
• Use when the electrode is cracked, corroded, or the ceramic insulator is damaged.
• Works as part of the appliance's ignition system alongside the spark module/igniter wiring.

• Turn off power and gas supply before beginning any service.
• Avoid touching or chipping the ceramic insulator; handle the tip carefully.
• Reconnect wiring exactly as removed and secure the electrode in the original orientation.
