Using this Fisher & Paykel fridge door closing hook stop is easy. First, locate the old hook on the right - hand side of your fridge door. Carefully remove the old hook by unscrewing it from the 4 holes. Then, align the new hook with the holes and screw it in place. Make sure it's firmly attached. As for maintenance, keep the hook clean by wiping it with a damp cloth regularly. Avoid using abrasive cleaners as they may damage the plastic. If you notice the hook is loose or not working properly, check the screws and tighten them if needed. Also, be gentle when opening and closing the fridge door to prolong the hook's lifespan.
