Using this defrost element is easy. First, make sure your refrigerator is unplugged. Then, locate the old defrost element and carefully remove it. Connect the new 120W aluminium defrost element using the 2 - pin and 3 - pin plugs as they were on the old one. Plug your fridge back in and it should start working. As for maintenance, keep the area around the element clean and free from dust. If you notice any signs of damage or the fridge isn't defrosting properly, check the element. And remember, if you're unsure about its suitability for your fridge, always provide your full model number before buying.
