Thermador Range / Cooktop / Oven Control Board

The Control Board is an OEM part for Bosch wall ovens. It serves as the main control center for the oven, managing and regulating all the functions, including temperature settings, cooking modes, timers, and the operation of the heating elements. 

Causes of a bad Control Board can include electrical surges, wear and tear from prolonged use, exposure to heat, and moisture or grease buildup that can damage electronic components.

Symptoms of a bad Control Board include:

• The oven not powering on or failing to respond to control inputs
• Display errors or malfunctioning display screen
• Inaccurate temperature regulation or inability to maintain set temperatures
• The oven not completing cooking cycles or shutting off unexpectedly

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

Oven won't turn on or display is blank? This power control board supplies power to your range's electronic controls. Moderate DIY repair, 1-2 hours.

This electronic PC board is the appliance's main control, processing inputs and directing power to components so cycles run correctly. Replacing a failed board can restore normal operation when the unit is dead, won't start, or stops mid-cycle.

• Interprets user inputs and sensor feedback to execute programmed cycles
• Switches relays to power motors, valves, heaters, and other loads as required
• Manages timing, temperature, and safety logic for consistent performance
• Typical failure symptoms: no power/won't start, unresponsive or erratic controls, cycles ending prematurely, recurring error codes

• Disconnect power before servicing; verify power is off with a meter
• Use ESD protection; handle the board by the edges to avoid static damage
• Move connectors one at a time to identical positions on the new board to prevent miswiring
• Some models require service-mode setup or calibration after installation—follow your model's service documentation

This kit includes a simmer control board that regulates low-heat burner operation on the cooktop, allowing precise temperature control at simmer settings. The board manages the cycling of the burner element to maintain consistent low temperatures. Replace this kit if your burners won't maintain a simmer, cycle erratically at low settings, or if the existing control board shows signs of damage or failure.

This is a rotary knob used on range or oven control panels to select cooking functions or temperature settings. It attaches to the control shaft and allows the user to easily adjust oven modes. Replace this knob if it is cracked, broken, or if the shaft connection has worn out, making it difficult to turn or select the correct settings.
