Thermador Range Hood Switch

The Vent Switch is an OEM replacement part for Bosch range hoods. It is an electronic control device located inside the range hood that regulates the internal vent and fan functions.

Causes of a faulty vent switch can include long-term use in high-heat cooking environments, damage from accidental spills or impacts, or normal component degradation over time.

Symptoms include:

• Failure of the fan or vents to engage during cooking  
• Variable or inconsistent fan speeds that don't adequately vent smoke
• Electrical shorting or sparking noises from within the hood control unit

This genuine Bosch replacement part is also compatible with Thermador, Gaggenau, and some Kenmore range hood models.

The Switch Speed Control is an OEM component specifically designed for select Bosch downdraft ventilation hoods requiring variable ventilation levels. As an adjustable regulator, it modulates blower velocities responding to modes selected by end users. 

Causes requiring replacement involve cumulative use wearing down switching components through continuous cycles. Physical impacts risk separating connections or shorting protected circuitry.

Symptoms signaling the need for a new speed control switch include: 

• Inability to adjust air exchange rates matching different cooking methods
• Erratic transitions between programmed velocities disrupting performance  
• Failure to consistently apply expected power levels to blowers

This OEM Bosch replacement component is also compatible with Thermador, Gaggenau, and some Kenmore ventilation hoods employing adjustable exhaust capacities. Correct installation restores intended variable operational control.
