Thermador Range / Cooktop / Oven Motor

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.
 

This replacement fan restores proper airflow inside your appliance, circulating air for cooling and overall performance. Replacing a worn or damaged fan helps keep temperatures in check and reduces noise from rubbing or imbalanced blades.

• Circulates air as designed to cool components and move heat/moisture where intended
• Common symptoms of a failing fan include loud scraping or rattling, weak or no airflow, wobble, or the fan not turning
• Heat buildup around the control area or repeated thermal shutdowns can point to a fan issue
• Physical cracks, broken fins, or warping indicate the fan should be replaced

• Disconnect power at the breaker; allow the unit to cool completely
• Access the fan per your model; remove panels/guards carefully and note orientation
• Transfer any retaining nut/clip or gasket from the original as required; seat the fan fully and secure
• Spin by hand to verify free movement; ensure no contact with shrouds before restoring power

This replacement transformer cooling fan circulates air to keep the power transformer cooler, helping maintain reliable operation and reducing heat-related stress on electrical components. Fits applicable Bosch appliances that use the 00487021 fan. What it does:

• Circulates air around the power transformer to dissipate heat.
• Helps prevent transformer overheating and heat-related failures.
• Can reduce excessive humming or intermittent operation caused by a failing cooling fan.
• Restores proper airflow that keeps nearby electronics within intended temperature ranges.

• Always disconnect power to the appliance before beginning any repair.
• Remove access panels and mounting hardware to replace the fan; note wiring orientation for correct reconnection.
• Handle the fan motor and blades carefully; avoid bending blades or damaging the connector.

This OEM replacement part is a motor assembly for ovens. The motor assembly is the main motor that powers the oven fan which is responsible for maintaining and adjusting the temperature in an oven. If the oven is no longer heating properly, turning on, or maintaining temperature, then the motor assembly will need to be replaced.To replace this part, make sure that the oven is unplugged. After it has been powered off, proceed to pull the oven out and away from the wall. Once moved, uninstall the back panel of the oven by removing the panel's mounting screws. After detaching the back panel, locate the motor housing on the back of the oven. Unthread the screws that hold the housing in place. Once removed, locate the mounting brackets that hold the motor in place and remove the screws that attach to the motor. Pull the old motor out of its place and install the new motor. Reinstall the back panel and restore power to the appliance.This genuine replacement part is sold individually and is compatible with Bosch, Gaggenau, and Thermador brand ovens.
