Using this blower fan is easy. First, make sure your dryer is unplugged to avoid any electrical hazards. Then, locate the motor in your dryer and attach the fan to one end of it. It's specifically designed to fit Simpson Eziset, EziLoader, and some Westinghouse and Electrolux late - model dual - direction dryers with a wide belt. When using your dryer, always follow the manufacturer's instructions for normal operation. As for maintenance, it's a good idea to check the fan regularly for any signs of wear or damage. If you notice any unusual noises or reduced performance, stop using the dryer and inspect the fan. Clean the fan every few months to remove dust and debris. Just use a soft brush to gently clean the blades. Remember, we've been in the appliance parts business for over 25 years, so if you have any questions, don't hesitate to contact us.
