Causes of Refrigerator Leaks
Maybe your water alarm alerted you, maybe you see a puddle or some dripping, or maybe you see some signs of water damage (corrosion, water stains, etc.). Once you’ve discovered a leak, consider the possible causes.
Blocked defroster. A blocked defroster can stop defrost-cycle water from draining properly. Try clearing out the small drain by pouring hot water into it. Remove any debris with a pipe cleaner.
Drain pan. Sometimes the drain pan itself can leak. Check for cracks.
Filter. Refrigerators with filters can leak if the filter is the wrong size or not installed properly.
Water line. This is potentially the most problematic. Refrigerators with ice makers or water dispensers have water lines running between the main water supply and the back of the fridge. Feel to see if the water line is wet or dripping. Cracked hoses and loose connections are often the culprit.
Refrigerator leaks can damage the flooring and cabinets in your kitchen. If you experience a refrigerator leak, please contact us right away to treat and help to prevent any further damage.
