Customer Questions and Answers for Switch, Speed Control by Bosch

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.
