Parts for Thermador REF30QB / PRIOR-9708: Drop-In Snorkel Assembly (Rdds30vqb(Prior-9707)) (Rdds30vrs(Prior-9707)) (Red30vqb(Prior-9707)) (Red30vqrs(Prior-9708)) (Red30vqw(Prior-9708)) Parts

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.

Knob, blk (cvs)

The Control Knob is an OEM part for Bosch ranges and cooktops. As the interface regulating gas flow, control knobs activate precise burner levels through internal calibration.

Causes of failure include loosened set screws beneath allowing knob slippage. Prolonged heat and moisture exposure may also degrade contact surfaces over time.

Symptoms of faulty knobs include:

• Burners failing to engage or not matching dial settings
• Inability to decrease output levels from full flame
• Knobs wobbling insecurely or detaching entirely

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

Color: metallic. Measures about 13-1/2 inches wide by 5 inches high.

The Grease Filter is an OEM part for Bosch ranges and cooktops. It is responsible for capturing and containing grease, oils, and other vapors produced from cooking to help keep indoor air fresh and prevent buildup. Regular cleaning is important to maintain optimal performance.

Causes of a bad grease filter can include excess buildup that blocks airflow from frequent high-heat cooking. Exposure to flames or excessive heat may cause damage over time as well.

Symptoms of a bad grease filter include:

• Reduced suction power and airflow from the range hood
• Grease accumulation on surrounding surfaces below the hood
• Unpleasant cooking odors escaping into the kitchen rather than being vented outside

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

This rear outer panel replaces a damaged or worn back cover on compatible Bosch units to restore safety and appearance. It provides a protective enclosure for rear components and helps keep wiring and parts shielded from damage. What it does:

• Covers and protects rear-mounted components and wiring from debris and accidental contact
• Restores a secure mounting surface for rear fasteners and brackets
• Replaces bent, corroded, or cosmetically damaged rear sheet metal
• Helps reduce draft and prevents small objects from entering the appliance rear

• Disconnect power and/or gas supply before beginning service
• Handle edges carefully—sheet metal can be sharp
• Typical installation requires removing rear access screws and transferring mounting hardware; retain original fasteners if reused

This bracket secures the dishwasher snorkel plug assembly to the tub, keeping the drain/anti-siphon connection stable for reliable draining and fewer leaks. Designed to match OEM fit and function. What it does:

• Holds the snorkel plug/anti-siphon assembly in the correct position to prevent movement during cycles
• Helps maintain a proper drain seal to reduce the risk of water leaks or backflow
• Restores proper routing of the drain/snorkel when a broken or missing bracket causes noise or loose fittings

• One snorkel plug mounting bracket

• Intended for use with compatible Bosch dishwashers; your model's parts diagram for placement
• Turn off power and water supply before beginning any repair
• Remove any nearby components carefully to access the mounting location; use basic hand tools
• If corroded fasteners are present, replace them with OEM-equivalent hardware to ensure secure mounting
