C301 Serial Parts

Oven door gasket seals the cavity to retain heat during cooking. Replace when torn, compressed, or allowing hot air leaks. Confirm fit by model number.

A replacement temperature sensor (thermistor) that monitors internal temperatures and sends readings to the appliance control board. Restores accurate temperature sensing to help cycles and temperature regulation run correctly. What it does:

• Measures internal temperature and relays readings to the control board so the appliance can adjust heating/cooling cycles.
• Helps ensure proper defrost or cycle timing by providing accurate temperature feedback.
• Common symptoms of a failing sensor: inconsistent temperatures, frequent or short cycling, or temperature-related performance issues.
• Works as a direct replacement for a worn or failed sensor to restore normal temperature monitoring.

• Disconnect power to the appliance before starting any repair to avoid shock or damage.
• Handle the sensor and wiring gently; avoid kinking or pulling the lead and ensure the connector seats fully.
• Installation typically requires access behind panels or inside the compartment—keep fasteners organized and follow the service manual.

This motor isolator is a vibration-damping grommet that cushions the motor mount to reduce noise and prevent metal-to-metal contact. Replacing worn isolators helps keep the motor seated correctly and the appliance running quieter and smoother.

• Cushions the motor to minimize vibration transfer to the chassis
• Helps reduce rattling or buzzing noises during fan/blower operation
• Supports proper motor alignment and mounting stability
• A common maintenance item when rubber mounts become cracked, hardened, or missing

• Disconnect power and allow hot components to cool before service
• Access the motor mounting points; replace isolators in matched locations
• Inspect adjacent mounts and hardware; replace additional isolators as needed
• Do not overtighten fasteners—compress the grommet evenly without deforming it

If your oven won't start or runs with the door open, this door interlock switch detects proper closure and latching. DIY repair in under an hour.

Covers and diffuses the indicator lamp on your cooktop control panel. Replace when cracked or missing to restore visibility and protect the opening. Confirm fit with your model number before ordering.

Screw: 8-16 x 3/8 inch.

Fix intermittent or failed burner operation caused by burnt or loose wiring. This wire harness restores reliable connections. 5-minute repair once disassembled.

This cooling fan assembly mounts inside the oven housing and circulates air to prevent the control panel and surrounding cabinetry from overheating during use. It typically runs during and after the oven's heating cycle to dissipate excess heat. Replace this assembly if the fan is noisy, doesn't spin, or if your oven's electronic controls are shutting down due to overheating.

Sheet metal pan head screw secures panels, brackets, and components to appliance cabinets. Replace missing, stripped, or corroded screws to restore fit.

A replacement fan (blower) that restores airflow in compatible Bosch appliances to support proper cooling and ventilation. Installs in the appliance's air path to help maintain temperature balance and reduce strain on other components. What it does:

• Circulates air through the appliance to support cooling and ventilation.
• Helps cool motors, heating elements, or evaporator areas depending on the model.
• Common symptom relief: reduces overheating, improves cooling performance, and can stop abnormal fan noise when the original fan fails.
• Prevents related faults caused by insufficient airflow when installed correctly.

• Always disconnect power to the appliance before starting any repair.
• Handle the fan blades and motor carefully to avoid damage; avoid forcing connectors or mounting points.
• After installation, test the appliance functions and listen for normal fan operation; if unusual noise persists, re-check mounting and clearance.

Fix intermittent power or component failure with this range socket electrical connector. Restores secure wiring connections in electric and gas ranges.

Oven lamp assembly provides interior lighting for viewing food during cooking. Replace when bulb burns out or housing cracks. Verify fit with your model.

Oven not heating or baking unevenly? This lower bake element restores consistent heat for even cooking. DIY-friendly repair in under 30 minutes.

Replacement mounting nut for securing internal oven and range components. Needed when original fastener is stripped, missing, or damaged during repair work.

Restore even baking when your oven heats unevenly. This convection fan blade circulates hot air for consistent cooking. Moderate DIY install.

This locknut is a small threaded retaining nut used to secure rotating and stationary appliance components, helping keep assemblies tight and stable during operation. It prevents parts from loosening and reduces vibration-related issues. What it does:

• Secures shafts, pulleys, or fittings to prevent axial movement
• Keeps assemblies fastened under normal vibration and load
• Helps stop wobble, grinding, or part separation caused by a loose connection
• Works with the matching threaded stud, shaft, or fitting for a proper hold

• Disconnect power and follow appliance safety procedures before servicing
• Use the matching thread size and engage threads fully; hand-start before tightening
• Tighten securely without overtightening; use the correct driver or socket for the nut
• Inspect mating threads and replace if damaged
