If your Samsung range hood is not effectively drawing air through the vent system, you might need to replace the fan motor assembly (DG81-02543A). This genuine Samsung part includes both the motor and fan blade, making it a comprehensive solution for your 36-inch externally vented range hood or 30-inch under cabinet hood. Before starting the installation, unplug your range hood or switch off the house circuit breaker. Wear work gloves for safety. Verify your appliance's model number for compatibility before purchasing.
