Using your Fisher & Paykel rangehood fan motor kit is easy. First, make sure your rangehood is turned off and unplugged. Locate the old motor and remove it carefully by unscrewing the 4 screws in the mounting cover. Then, take your new motor kit and use the 4 screw holes to mount it in place. Connect the start/run capacitor and the mains cable as per the original setup. Once everything is connected, plug in your rangehood and turn it on. For safety, always double - check all connections before powering on. When it comes to maintenance, keep the motor clean. You can use a soft, dry cloth to wipe it down every few months. If you notice any strange noises or reduced performance, it's a good idea to have it checked by a professional. Don't try to disassemble the motor on your own as it may void the warranty.
