Parts for Thermador PRD484EEHU/01: Control Panel 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 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

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 rotary potentiometer converts shaft rotation into an electrical signal the control board can read, providing precise position feedback for user selections. Replace it if inputs become erratic, jump between settings, or the control stops responding.

• Provides rotary position feedback to the electronic control
• Enables accurate selection and adjustment of functions or setpoints
• Wear or damage can cause drifting, dead spots, or incorrect readings
• Intermittent or no response to input is a common failure symptom

• Disconnect power before servicing
• Access the control/console area to reach the component
• Note shaft orientation and any connector positions; transfer exactly to the new part
• Handle electronics with ESD care and verify smooth, full-range operation after reassembly

This temperature regulator is the mechanical thermostat that controls oven heat. It senses cavity temperature and cycles the heat source on and off to reach and maintain your set temperature for consistent baking and roasting performance. What it does

• Senses oven temperature via a capillary bulb and tube
• Opens and closes internal contacts to control the heating source
• Maintains the selected temperature during cooking cycles
• Help resolve: oven not reaching set temp, overheating or wide swings, uneven baking, or unresponsive temperature control

• 1 temperature regulator

• Disconnect power; shut off gas. Allow the appliance to cool completely
• Note the original routing of the sensing bulb and capillary; reinstall the new one in the same path and clips. Do not kink, sharply bend, cut, or shorten the tube
• Transfer any knob/shaft components as needed and align properly
• After installation, verify temperature with an oven thermometer and adjust per service instructions if applicable

This replacement control knob restores a secure, easy-to-turn grip on your appliance's control shaft. Replace a cracked, stripped, or missing knob to accurately select settings and keep daily operation simple.

• Interfaces with the control shaft to turn the appliance on/off and adjust settings
• Replaces knobs that are cracked, stripped, loose, or missing
• Helps maintain proper alignment with indicator marks for accurate selection
• Typical signs include wobbling, falling off, or failing to engage the switch/valve

• Disconnect power and let any hot surfaces cool before servicing
• Pull the old knob straight off the shaft; avoid prying that could damage the panel
• Align the new knob's flat side or splines with the shaft and press firmly until seated
• Verify smooth, positive engagement of the control after installation
