To change the filter on a side-by-side refrigerator, locate the water filter compartment (this may be at the back of the fridge or inside one of the refrigerators in a corner). Remove shelving if needed to make replacing the water filter easier. Open the water filter cover and twist or click the filter to release it. Place the new filter into the compartment and twist or click it to secure it in place. Follow the manufacturer's instructions to prime the filter and reset the filter change light (if there is one).
