Using this evaporator fan motor is quite simple. First, make sure your fridge is unplugged for safety. Locate the old fan motor in your no - frost fridge. Remove it carefully and note how it was connected. Then, connect the new motor using the 45cm connecting wires with bare ends. You can adjust the rotation direction (CW or CCW) if needed by taking off the bearing covers and re - positioning the rotor. Fit the motor into the metal or plastic bracket using the rubber grommets at the front and back. Finally, plug your fridge back in. As for maintenance, keep the motor clean from dust and debris. Check the wires regularly for any signs of wear. If you notice any strange noises or performance issues, stop using the fridge and get in touch with a professional. And remember, this motor comes with a full guarantee, so you're covered.
