Symptoms of a failed light lens include:

• Diminished or inefficient lighting of the oven interior
• Hot or cold spots within the oven due to poor visibility 
• Possible melting or scorching of food items without consistent light

This OEM Bosch replacement part restores full illumination for effective use of the wall oven. It is also compatible with Thermador, Gaggenau, and some Kenmore wall oven models.
 

This door seal restores a tight barrier between the oven door and cavity. Replacing a worn gasket helps your oven reach and hold temperature, reduces heat escaping at the door edges, and supports more consistent baking and roasting results.

• Creates a heat-resistant seal around the oven opening
• Helps the oven preheat and maintain set temperature
• Limits heat, steam, and odors from escaping at the door
• Typical signs it needs replacement: visible tears or flattening, heat felt around the door, longer preheat/cook times, or uneven baking

• Disconnect power at the breaker and let the oven cool completely
• Open the door, pull the old seal from its channel, and clean the groove
• Press the new seal evenly into the channel without stretching; ensure corners seat fully
• Close the door to verify uniform contact all around and adjust as needed

This dishwasher water sensor monitors wash-water conditions so the control can adjust cycle time, rinses, and heating for consistent performance. Replace a failed sensor to restore reliable cleaning results and proper automatic cycle adjustments. What it does

• Detects water conditions during the wash cycle and reports to the control
• Helps the dishwasher optimize cycle length, rinses, and energy use
• Common symptoms: unusually long or short cycles, inconsistent cleaning, or sensor-related error messages
• Trigger erratic cycle behavior when the sensor is faulty or contaminated

• One sensor assembly

• Disconnect power and turn off water before servicing
• Access is typically from the underside; place a towel or pan to catch residual water
• Transfer/seat the seal properly if present; fully engage the locking tabs and reconnect the harness
• After installation, run a quick cycle and check for leaks and proper operation

This factory replacement heating element restores proper heat during operation. When the original element is burned out or damaged, installing this part brings temperatures back to spec for reliable cycle performance and effective cleaning, drying, or heating results. What it does:

• Heats water or air to the target temperature as designed by the appliance
• Common symptoms include no heat, lukewarm operation, extended cycle times, poor drying results, or heating-related error codes
• Electrical connections match the original layout on applicable models
• Built to original specifications for consistent, even heating

• 1 heating element

• Disconnect power before servicing; shut off water supply if applicable
• Allow the appliance to cool completely before handling the element

• After installation, check for leaks and run a test cycle to ensure proper heating

The Fan is an OEM component specifically designed for select Bosch built-in ovens. As a critical convection element, it circulates internal air currents for optimal heat distribution throughout baking and broiling cycles.

Powerful yet precisely balanced centrifugal motion agitates spacious oven cavities with homogeneous warmth. Aerodynamic fan blades expedite even cooking without hot or cold spots. 

Causes requiring replacement relate to bearing seizure or broken blade attachments disrupting designed circulation. Prolonged heat exposure may cause premature motor failure or cracked housings to no longer sustain needed speeds.

Symptoms signaling the need for a new fan include:

• Inability to effectively circulate air for simultaneous multi-rack cooking  
• Louder than average operation noise accompanied by vibration
• Erratic or ineffective temperature management within cycles

This OEM Bosch replacement fan is also compatible with Thermador, Gaggenau, and some Kenmore built-in ovens employing convection methods. Proper reinstallation restores designed air transfer capabilities for perfect results.
 

The Oven Door Seal is an OEM part for Bosch ovens and ranges. This door seal fits snugly around the outer edge of the oven door to provide an effective air seal when closed.

Causes of a bad door seal can include damage from normal wear and tear over time, compression from repeated opening and closing of the door, or heat exposure leading to cracking or warping.

Symptoms of a bad door seal include:

• Inefficient or slow heating
• Inability to maintain set oven temperature
• Increased energy costs
• Smoke escaping around door edges when baking

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

This replacement glass panel restores the smooth, protective surface on the appliance when the original panel is cracked or broken. It helps maintain a clean appearance while shielding the components mounted behind the glass. What it does:
