Customer Questions and Answers for Cooling Fan Assembly by Lg

This fan assembly moves air through the unit to cool internal components and maintain proper ventilation. Replacing a worn or seized fan restores correct airflow, helps prevent overheating, and reduces excessive noise from a failing motor or wheel.

• Circulates cooling air across internal components to prevent overheating
• Exhausts air through the vent/duct path for proper ventilation
• Common symptoms: fan not running, weak airflow, or loud rattling/squealing
• Unit may overheat or shut off during use when the fan fails

• Disconnect power before service; microwaves contain a high-voltage capacitor that can retain a dangerous charge—follow proper safety procedures.
• Remove access panels to reach the fan housing; note airflow direction and wire orientation.
• Transfer any brackets, grommets, or screws from the original assembly if required.
• After installation, verify the wheel spins freely and airflow direction is correct before reassembly.
