Using this blower fan is easy. First, make sure your dryer is unplugged. Then, locate the old fan on the end of the motor and carefully remove it. Take your new fan and align it properly with the motor shaft, then gently push it on until it fits snugly. When it comes to maintenance, keep the fan clean. You can use a soft brush to remove any dust or debris that might build up on the blades. For safety, always double - check that the dryer is off and unplugged before you start any work on it. If you have any problems during installation or use, don't hesitate to contact us. We've been in the appliance parts business for over 25 years and are here to help you.
