Parts for Thermador SGN30S: 11 - Integral Ventilator Parts

A protective terminal boot that slips over a capacitor connection to shield it from moisture, dirt and accidental contact, helping reduce risk of shorts and maintain a reliable electrical connection. What it does:

• Covers the capacitor terminal to reduce the chance of accidental contact and arcing.
• Protects the terminal from moisture, dust and debris that can compromise electrical connections.
• Helps prevent corrosion and keeps the terminal area cleaner for more reliable operation.
• Signs it may be needed: cracked, torn or missing boot; visible arcing or burn marks near the capacitor; intermittent electrical behavior that points to a compromised connection.

• Always disconnect power and unplug the appliance before working on electrical components.
• Discharge the capacitor per OEM instructions before touching terminals to avoid shock.
• Push the boot fully onto the terminal for a snug fit; ensure no wiring is pinched or under strain.

A locknut that secures threaded shafts and fasteners in appliances to resist loosening from vibration and maintain stable component alignment. Replacing a damaged or stripped locknut restores a secure fastening and reduces rattling or movement. What it does:

• Keeps nuts and components locked on threaded shafts to prevent backing off under vibration.
• Commonly used where a retained fastener is required on motors, pumps, or moving assemblies.
• Replace if you notice loose parts, persistent rattling, or visible thread damage.
• Restores proper fastening to help prevent premature wear or component misalignment.

• Disconnect power (and water/gas if applicable) before servicing the appliance.
• Use the correct size socket or wrench and hold the mating component to avoid over-torquing.
• Inspect mating threads and replace any damaged hardware to ensure a secure fit.

This blower wheel circulates air through the appliance's convection/ventilation system to restore proper airflow and consistent temperature control. A direct-fit replacement that re-establishes designed air movement when the original wheel is worn or damaged. What it does:

• Spins on the blower motor to move air through the appliance for cooling, venting, or convection cooking.
• Restores airflow when a broken, cracked, or missing wheel causes weak airflow or uneven temperatures.
• Reduces unusual noises caused by a damaged or imbalanced blower wheel.
• Helps prevent overheating by ensuring proper ventilation when functioning correctly.

• One blower wheel (CVHSB) — ships as described.

• Disconnect power to the appliance before starting any repairs to avoid electric shock.
• Inspect the motor shaft, housing, and mounting hardware for damage; replace any worn components for a secure fit.
• Ensure the wheel is oriented and seated correctly on the motor shaft and tightened per manufacturer practice.
• Use gloves and eye protection.

This TH capacitor is an electrical control-circuit capacitor used on compatible Bosch appliances to help stabilize voltage and filter electrical noise for reliable control-board operation. Replacing a failed capacitor can address intermittent control issues. What it does

• Stabilizes control-board voltage and helps filter electrical noise that can cause erratic behavior.
• Supports reliable startup and operation of control circuits.
• Common symptom link: intermittent or unexplained control-board errors, erratic or non-responsive controls.
• Common symptom link: appliance displays control or error codes related to electronics or intermittently fails to start.

• Disconnect power to the appliance at the breaker before servicing to avoid shock.
• Discharge any capacitors and allow boards to sit before touching components; use appropriate ESD precautions.
• Only replace with the exact part number; confirm orientation and connector fit before reassembly.
