Thermador Cooktop Parts

This LP main jet regulates propane flow to a surface burner to maintain a clean, stable flame. Replace a clogged or incorrect jet to restore proper burner performance, especially when converting a cooktop or range from natural gas to LP.

• Meters LP gas to the burner head for correct flame size and combustion
• Direct replacement for a damaged, clogged, or incorrect jet during service or LP conversion
• May help with yellow/sooty flames, weak or overly high flames, uneven heating, or delayed ignition

• Shut off gas and power; allow the appliance to cool completely
• Remove grates, caps, and burner head to access the orifice holder
• Start the jet by hand, then tighten gently with the correct tool—do not overtighten
• After installation or any LP conversion, leak-test connections and verify a steady blue flame; other jets and the regulator may also require LP settings per the model's instructions

This ignition device generates the spark needed to light gas burners, restoring reliable ignition and preventing continuous clicking or no-light conditions. Replace a failed module to re-establish normal burner ignition. What it does:

The Surface Element is an OEM part for Bosch cooktop and ranges. Measuring 6 inches across, it provides focused heat from below for smaller sized cookware.

Causes of a bad 6" plug-in element generally relate to normal wear and tear over time. Spills left on the coils could potentially cause issues by corroding internal wiring or damaging heating components.

Symptoms of a bad narrow surface element can include:

• The element heating intermittently or not at all
• Only parts of the coil visibly heating up
• Buzzing or clicking coming from below the element
• Tripped circuit breakers affecting that specific element

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

The Burner Cap Assembly is an OEM part for Bosch ranges and cooktops. It refers to the rounded caps placed over each burner to contain and direct flames safely.  

Causes of a bad burner cap assembly can include warping, cracks or punctures from consistent high heat that allow flames to escape improperly. Surface scratches likewise compromise insulation and durability over time.

Symptoms of damaged or faulty caps are:

• Excessive flames licking up beyond cap borders
• Scratches or cracks visible on hot surfaces
• Difficulty adjusting flame height precisely
• Burners do not heat evenly or shut off completely

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

The Surface Element (240V-2100W) is an OEM part for Bosch cooktops and ranges. It provides consistent, even heating from below pans on the cooktop surface.

Causes of a bad surface element can include normal wear and damage from extended, heavy usage. Food or liquid spills left on the element for prolonged periods could potentially corrode the coils or electronics over time as well.

Symptoms of a bad surface element include:

• Element not heating up at all or heating unevenly
• Element heating intermittently or stopping prematurely
• Buzzing, clicking or smoke coming from below the element
• Tripped or blown circuit breakers when using that element

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