Parts for Thermador PRD366EHC/05: Control Panel Parts

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

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.

The Potentiometer is an OEM replacement part for Bosch gas range or cooktops. It functions as a three-terminal resistor that adjusts the flow of electric current, which in turn, controls the ignition and temperature of the cooktop. This component is essential for the precise operation and control of the gas burners, ensuring they light up and maintain the desired flame intensity.

Causes of a malfunctioning Potentiometer can be attributed to wear and tear, electrical issues, or damage due to spills and cleaning products. A compromised potentiometer affects the flow of electric current, leading to issues with the ignition and temperature control of the gas burners.

Symptoms of a bad Potentiometer include:

• The cooktop not lighting or staying lit
• The ignitor continuously clicking without igniting the burner
• Inability to adjust the flame intensity or temperature accurately

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

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
