Using this fan motor is easy. First, make sure your fridge is unplugged to avoid any electrical shock. Find the old fan motor in your no - frost fridge and carefully remove it. Then, take your new fan motor and connect the 100mm wires with 6.4mm male spade terminals to the appropriate connectors. Clamp the motor into the metal or plastic bracket using the rubber grommets on the front and back. Once it's securely in place, plug your fridge back in. When it comes to maintenance, keep the motor clean. You can use a soft, dry cloth to wipe off any dust. If you notice any unusual noises or the motor doesn't seem to be working properly, unplug the fridge right away and contact a professional. Also, make sure the environment around the fridge is well - ventilated to prevent the motor from overheating. And remember, this motor is fully guaranteed, so if you have any problems, you can rely on our support.
