Parts for Bosch HSLP451UC/01: Convection Parts

The Temperature Sensor is an OEM replacement part for Bosch gas ranges. It provides precise feedback to the control board, allowing perfect burner temperature regulation throughout all cooktop settings. Accurate monitoring optimizes cooking results.

Causes of a bad temperature sensor can involve failure from everyday overheating during high flame use stretching its limits. Corrosion from spills affects conductivity over time as well. 

Symptoms of a bad temperature sensor include:

• Inability to maintain set heat levels, burners cycling uncontrollably
• "Error" or number codes shown as the board detects abnormal readings  
• Temperature gauges on displays jump erratically instead of steadying
• Potential safety issues arise from unchecked excess heat exposure

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

This interior oven lamp provides illumination inside the oven cavity so you can check cooking progress without opening the door. It replaces a failed or dim lamp to restore clear, usable light. What it does:

• Replaces the oven cavity light to restore visibility while cooking
• Helps you monitor food without opening the oven door, reducing heat loss
• Commonly used when the bulb is burned out, flickering, or very dim
• Fits the oven light housing and pairs with the existing socket and lens assembly

• One interior oven lamp

• Turn power to the appliance off at the breaker before servicing to avoid electrical shock
• Allow the oven to cool completely before accessing the lamp area
• Handle the lamp carefully; avoid touching glass with bare hands if specified by OEM

A replacement glass light cover that protects and diffuses the oven interior light so you can see food while cooking. Restores proper light diffusion and keeps the bulb shielded from spills and debris. What it does:

• Protects the oven light bulb from splashes, food particles, and direct contact
• Diffuses and softens interior light for even visibility while cooking
• Helps prevent glass fragments from reaching food if the bulb breaks
• Commonly replaced when cracked, chipped, cloudy, or causing reduced illumination

• Disconnect power to the appliance before starting any work; allow the oven and bulb to cool.
• Handle the glass carefully to avoid chipping or cuts; wear gloves and eye protection.
• Installation normally requires removing the old cover and securing the new cover per the oven's light assembly—retain any mounting clips or screws.

This heater ring secures the dryer's heating assembly and helps direct airflow through the heater area for more consistent operation. It replaces a worn or damaged mounting ring to restore proper heater alignment and airflow. What it does:

• Holds the heating element assembly in place and maintains correct spacing to the housing
• Helps channel heated air through the heater compartment for even drying
• Can prevent rubbing or shorting from a loose heater element
• Common symptoms: intermittent or no heat, uneven drying, or visible damage/corrosion at the heater opening

• Disconnect power at the breaker or unplug the appliance before starting any repair
• Allow the unit and heater components to fully cool to avoid burns
• Remove exterior panels or drum as required for access; keep fasteners organized for reassembly
• Inspect surrounding insulation, element, and wiring for damage while the ring is replaced

The Fan Motor is an OEM part for Bosch ovens that drives the convection fan, which is responsible for circulating hot air throughout the oven during the convection cooking process.

A bad fan motor can occur due to wear and tear over time, electrical malfunctions, or physical damage. Signs of a faulty assembly include the convection fan not spinning, noisy operation, or inadequate airflow.

Symptoms of a bad fan motor include:

• The fan not spinning or operating at a reduced speed
• Unusual noises coming from the fan motor
• Inadequate airflow or uneven cooking 

Replace your malfunctioning fan motor with this genuine OEM Bosch part to restore your oven's convection feature. This Bosch part can also be used on Thermador and Gaggenau appliances.
