This is a genuine OEM replacement o-ring sourced directly from the manufacturer for use on range vent hood switches. The o-ring provides a tight seal for the switch and keeps smoke from escaping through the switch connection. If the o-ring becomes worn or damaged, the vent will not remove smoke during cooking and should be replaced. Heat and debris pulled through the vent may cause the o-ring to warp. O-rings are not designed to last forever and may need to be replaced during the life of the appliance to keep it functioning correctly.To start, disconnect the power to the vent hood and dismantle the vent in order to reach the switch. To start, disconnect the switch and locate the o-ring. Remove the old one and dispose of it. Place the new o-ring in the groove and press firmly to seal the part. Lubrication is not necessary for installing the new o-ring. Reassemble the switch and put the vent hood back in place. Connect the power and try the switch to make sure it works. This o-ring is made of heavy-duty black rubber is and sold individually. It is designed for use in range hoods manufactured by Thermidor.

The Vent Control Button is an OEM component specifically designed for select Bosch downdraft ventilation ranges. Pressable from the countertop, its reliable switch operates the vent position. Precise guidance aligns ductwork airflows. 

Symptoms of a faulty control button may include intermittent or unresponsive vent movement. Over-activation degrades contacts requiring change. 

Causes of a bad button relate to typical contact wear reducing conductivity. Splashes introduce moisture necessitating replacement over time.

Causes of a bad vent control button involve:

• Vents remaining stuck open exposing grease-laden air  
• Closed vents trapping cooking emissions near surfaces
• Failure to change vent direction as needed 

This OEM Bosch part is also compatible with some Thermador, Dacor, and Viking downdraft ventilation ranges. Replace to maintain convenient vent management directing smoke and odors safely outdoors.
 

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.
