Finding the cause of water dripping on the floor from your Kirkland top-mount refrigerator
It's not unusual for a refrigerator to drip a little water on the floor after you replace the water filter—air trapped in the water dispenser system can make the water dispenser drip enough to overflow the drip tray below the dispenser. You can fix it by streaming a gallon or two of water through the dispenser to eliminate the trapped air.
If water drips on the floor from the back of the refrigerator, a leaking water inlet valve or cracked water system tubing could be the cause. A clogged or cracked defrost drain tube could also cause the leak. Defrost condensate water collects in the drain pan at the bottom of the refrigerator so a cracked or overflowing drain pan can also cause water to drip on the floor behind the refrigerator. Check the drain pan for cracks and clean out any foreign objects that may be inside the drain pan.
Excessive frost caused by a leaking door seal can also cause the defrost drain pan to overflow. Check the door gaskets and replace them if damaged.
Troubleshooting the ice maker in your Kirkland top-mount refrigerator
Several problems can interfere with making ice. The ice maker could be jammed or broken, a dirty water filter or kinked water line could be blocking water flow or the water inlet valve could be clogged or faulty. Check the ice maker for jammed cubes and clear any ice buildup that you find. Replace the ice maker assembly if it doesn't cycle when activated. Replace the water inlet valve if it's clogged or won't fill the ice maker when activated. Replace any damaged or clogged water system tubing.
No ice in the ice maker also could mean that your refrigerator isn't cooling-the ice maker won't cycle if the freezer is warmer than 5 degrees F. Check for problems that could prevent the freezer from cooling such as dirty condenser coils or a damaged freezer door gasket.
