Using this replacement fan motor is easy. First, turn off and unplug your Dyson DC23 or DC32 vacuum cleaner. Then, carefully remove the old motor and transfer the cooling fan from it to the new motor. Once the cooling fan is in place, install the new motor in the vacuum cleaner. When using the vacuum cleaner, make sure it's on a flat surface and don't overwork it for long periods. As for maintenance, regularly check the motor for any signs of dust buildup. You can use a soft brush to gently clean the outside of the motor. If you notice any strange noises or reduced performance, it might be a good idea to check the motor again. Remember, if your cooling fan is damaged, you need to get a genuine motor. With proper use and maintenance, this replacement motor will serve you well for a long time.
