Water supply lines leading to icemakers or water dispensers can leak and puddle under the fridge. There are several other causes of Refrigerator water leaks. The refrigeration system produces water in the form of condensation and melting ice. When systems that deal with water removal fail or the unit is producing excessive ice buildup, puddles either inside and/or outside of the unit result.
There are several checks and easy fixes you can try.
- Refrigerator Leaking DIY Fix 1
Check the water lines. Plastic lines can fail over time. Check for small pin hole leaks across entire length of line. If you observe any problems with plastic lines, replace the entire line rather than repair the leaking section alone. Copper Lines are more durable but can fail especially if the refrigerator has been moved. Check for leaks at any kinks and at the couplings at both ends of the line. If you find leaking couplings, replace rather than repair.

As a norm, refrigerators will drain excess water into a pan beneath the unit. If the pan is faulty or if the refrigerator is tilted badly, water can spill out of the pan. Leveling the refrigerator or replacing the pas as appropriate will resolve this. You can generally access the pan from the rear of the refrigerator. Leveling is achieved by adjusting the feet on the front and rear. While you are there, use a vacuum cleaner to remove the years of dust and grime that has accumulated on the coils. Remember UNPLUG the refrigerator from Power 1st to prevent electrical shock. Also be cautious moving the unit to prevent damage to water lines and floors.

The Freezer has a drain strategically situated to drain off any excess water during a defrost cycle. If the drain becomes obstructed wither due to freezing or debris, water leaks will result in the fresh food section below. Locate where the drain is – involves removing panels to the rear or side of the freezer compartment. In some models, the floor panel may need to also be removed. Use a hair dryer to melt any ice buildup mopping away any melt off. Clean around the drain hole and blow air through the drain tube to ensure blockages are blown out and ensure it is clear. If you use an air compressor ensure pressure is well below 30PSI.
More complicate repairs involving leaking could also result from defrost cycle issues or excessive ice buildup. This could be caused by a variety of issues ranging from a defrost heater timer, to a control board or even a problem with the sealed system. These are generally best left to the pros to handle.
