Parts for Thermador PRG484ECG02: Control Panel Parts

This display is the user interface module that shows cycle status, settings and error indicators so you can read and control the appliance from the front panel. It restores visible feedback and menu information for normal operation. What it does

• Provides the visible display for cycle progress, timers and selected options
• Shows error codes and status messages to help identify issues
• Works with the appliance control board to update settings and user inputs
• Restores readable display after a failed or cracked panel

• Disconnect power to the appliance before starting work to avoid shock or damage
• Replacement typically requires removal of the front control or console panel; handle the display lens and ribbon connectors carefully
• Keep screws and small fasteners organized for 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.

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 is a replacement rotary potentiometer for appliance control panels—provides smooth variable input for temperature/speed/setting adjustments so the appliance responds correctly to user control changes. What it does:

• Acts as the variable resistor that the control knob uses to set temperature, speed, or other settings
• Restores accurate user input when original control becomes intermittent, jumps, or fails to change settings smoothly
• Helps eliminate erratic readouts or unresponsive knob adjustments linked to a worn or faulty potentiometer
• Works as the electronic interface between the knob and the appliance control board

• Disconnect power before accessing internal control panel to avoid shock or damage
• Handle PCB and connector pins carefully; avoid bending leads or contaminating contacts
• Replace only with the exact part number listed and reassemble panel alignment before testing

The Switch Selector is an OEM replacement part for Bosch ranges. It serves as the electronic interface controlling the various cooking modes and functions. Precise switching operation is necessary for reliable selection of bake, broil, warming, and other settings.  

Causes of a bad switch selector include normal wear and tear from repeated use over extended periods. Exposure to liquid spills, steam, or cleaning chemicals may degrade internal electronic components.

Symptoms of a bad switch selector include: 

• Inability to select desired modes or functions
• Settings that automatically cancel or change  
• Non-responsive buttons that do not depress properly   
• Lighted displays flickering or failing to illuminate

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

Restore confident control of your appliance with this replacement control knob. It slides onto the control shaft to provide a secure, accurate grip so you can easily select settings when the original knob is cracked, stripped, or missing. What it does:

• Attaches to the control shaft to select temperature, cycle, or power settings
• Restores positive engagement and smooth turning of the control
• Helps resolve a loose, wobbly, or slipping selector
• Replaces knobs that are cracked, broken, or won't stay on

• One control knob

• Disconnect power; for gas appliances, also shut off the gas supply before servicing
• Pull the old knob straight off the shaft; if your model uses a set screw or clip, loosen/remove it first
• Align the new knob with the shaft and press on firmly; retighten any set screw if present
• Test operation to ensure the knob engages and turns the control smoothly

This is a round control knob that restores secure grip and accurate control for a range, cooktop, or oven control shaft. Replaces a cracked, stripped, or missing knob so controls turn smoothly and reliably. What it does

• Fits onto a standard control shaft to change heat or function settings.
• Replaces a broken, loose, or missing knob that won't turn or slips on the shaft.
• Restores tactile grip and precise adjustments for temperature or burner selection.
• Helps prevent accidental setting changes caused by a damaged knob.

• One control knob.

• Turn appliance controls to OFF and disconnect power (or gas) before working on the appliance.
• Pull the old knob straight off the control shaft; align splines and push the new knob on until seated.
• If knob resists, verify correct orientation of splines and avoid excessive force.
