Using this evaporator fan motor is quite simple. First, make sure your fridge is unplugged for safety. Then, find the right spot in your fridge to clamp the motor into the metal or plastic bracket using the rubber grommets. Connect the 50cm wires with bare ends to the appropriate terminals in your fridge. You can adjust the rotation direction according to your needs by undoing the bearing covers and re - fitting the rotor. When using, always ensure the fridge is operating at the correct voltage (240Volts AC). As for maintenance, keep the motor clean. You can use a soft brush to gently remove any dust from time to time. If you notice any strange noises or the motor doesn't work properly, it's best to check the connections first. And remember, this motor comes with a full guarantee, so if there are any issues, feel free to contact us.
