Using this Fisher & Paykel defrost element is straightforward. First, make sure your fridge or freezer is unplugged for safety. Then, locate the old defrost element in the freezer compartment. Remove the old one by unplugging the 2 - pin plug and any mounting screws. Install the new element in the same place and plug in the 2 - pin plug. After that, you can plug your fridge or freezer back in. As for maintenance, keep an eye on the defrost cycle. If you notice any signs of overheating or if the element isn't working properly, turn off the appliance immediately and check for any visible damage. For long - term use, it's a good idea to clean the freezer regularly to prevent dust and debris from building up on the element.
