Using this Fisher & Paykel defrost element is easy. First, make sure your refrigerator or freezer is unplugged for safety. Then, carefully remove the old defrost element and install this new one in its place. Ensure all connections are secure. When it comes to the wiring, if it has a 2 - pin plug, just plug it in. If not, connect the wires according to the color - coding or your appliance's manual. As for maintenance, keep the defrost element clean. Wipe it gently with a dry cloth every few months to remove any dust or debris. Be careful not to use any sharp objects that could damage the element. And remember, if you're unsure about any part of the installation or maintenance, it's always a good idea to consult a professional.
