Using this blower fan is easy. First, make sure your dryer is unplugged to avoid any electrical hazards. Locate the motor in your AEG or Electrolux condenser dryer and attach the fan to one end of it. When using your dryer, keep an eye on the performance of the fan. If you notice any unusual noises or vibrations, stop using the dryer right away. For maintenance, clean the fan regularly to remove any dust or debris. You can use a soft brush to gently clean the blades. Make sure to handle the fan carefully to avoid any damage to the 9.7mm D - shape shaft. If you have any further questions, feel free to contact us.
