Using this Fisher & Paykel fridge door closing hook stop is easy. First, make sure your fridge is turned off. Then, find the spot on the left - hand freezer door where the old hook stop was attached. Remove the old one and align the new hook stop with the 4 holes. Use appropriate screws to secure it in place. Once it's installed, turn your fridge back on. As for maintenance, keep it clean by wiping it with a damp cloth from time to time. Avoid using abrasive cleaners as they might damage the plastic. If you notice any cracks or if the hook stop doesn't seem to be working properly, it's time to replace it. Always remember to follow safety guidelines when working around your fridge.
