Parts for Thermador PRD48JDSGU/08: Manifold Parts

The Solenoid Valve is an OEM part for Bosch ranges. Located inside the control panel, the solenoid valve regulates gas to individual burners during the cooking cycle. It opens and closes electrically to direct fuel when its paired control knob is turned on.

Symptoms of a bad solenoid valve include:

• Inability to ignite or maintain a flame on specific burners 
• Burners failing to respond to control settings
• Hesitation or delay in burner engagement
• Range functions in an unpredictable manner

Causes can involve normal wear of moving internal parts, mineral buildup inhibiting valve movement, or physical damage. Failure reduces the range's functionality and safety.

This OEM Bosch part is also compatible with Thermador and Gaggenau models.

This replacement screw secures appliance panels and components in their proper position. Installing this screw restores a solid, factory fit and helps prevent vibration and misalignment.

• Fastens panels, brackets, or internal parts to the appliance chassis
• Maintains alignment to reduce vibration and rattling noises
• Replaces missing, rusty, or stripped hardware
• Typical symptoms include loose panels, gaps, rattles, or a screw that won't tighten

• Disconnect power (and shut off water or gas, if applicable) before servicing
• Support panels and watch for sharp edges and pinch points
• Use the correct driver size/type for your model to avoid stripping
• Start threads by hand to prevent cross-threading; tighten snugly without over-torquing

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 potentiometer is the rotary sensor behind the control knob. It converts knob rotation into an electrical signal the control board uses to adjust settings, restoring smooth, accurate response when a worn or erratic control causes inconsistent operation.

• Translates knob rotation into a variable-resistance signal for the electronic control
• Enables the control board to regulate power/heat or speed, depending on model
• Common failure symptoms: unresponsive or jumpy settings, dead spots when turning, or settings that drift
• Helps restore precise, repeatable adjustments at the knob

• Disconnect power to the appliance before servicing
• Pull off the knob and open the control panel to access the potentiometer
• Move wires one at a time to the new part; align the shaft/flat to the knob as noted
• Reassemble and test full range of adjustment; follow any model-specific calibration if required

Replacement water inlet valve that controls an appliance's incoming water flow for reliable fill and cycle operation. Replacing a faulty valve can stop no-fill, slow-fill, or continuous-fill issues and restore normal performance. What it does:

• Opens and closes to regulate water entering the appliance during fill cycles.
• Helps ensure correct water levels for proper washing or rinsing.
• Common symptom fixer for appliances that won't fill, fill slowly, or keep filling.
• May cause visible leaks at the valve or trigger fill-related fault behavior if failed.

• Turn off power and shut off the water supply before starting any work.
• Open a cycle or relieve pressure to drain residual water before removing the old valve.
• Inspect and replace any worn seals or inlet hoses when installing the new valve.
• Follow the appliance service manual for specific removal/installation steps.

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.
