A puddle under or inside your fridge is never a welcome sight. The good news: most fridge leaks don't require a technician. Here are the most common causes and how to fix them yourself.
Fix 1: Unclog the Defrost Drain
The most common cause of leaks is a blocked defrost drain. It's usually at the back of the freezer floor. Use warm water and a turkey baster to flush it clear, or carefully use a pipe cleaner to remove ice blockages.
Fix 2: Level the Refrigerator
If your fridge isn't level front-to-back, water from the defrost cycle won't drain properly. Use a spirit level on top of the fridge and adjust the front feet until it tilts slightly back.
Fix 3: Inspect the Water Supply Line
If your fridge has an ice maker or water dispenser, check the plastic supply line at the back for cracks or loose connections. Tighten fittings and replace cracked tubing.
Fix 4: Check the Door Gaskets
Worn door seals let warm air in, causing excess condensation. Do the paper test: close a piece of paper in the door. If it slides out easily, your gaskets need replacing.
Fix 5: Empty and Clean the Drain Pan
The drain pan under the fridge collects defrost water. If it's cracked or overflowing, it'll leak onto the floor. Pull out the pan (usually at the bottom front) and check for damage.
Fix 6: Check the Ice Maker
A misaligned ice maker fill arm or faulty inlet valve can dump excess water that leaks out. Make sure the fill arm is in the 'up' position when not in use.
Conclusion
Fridge leaks are almost always DIY-fixable. Start with the defrost drain — it's the culprit in 80% of cases. If your fridge is level, drain is clear, and gaskets are good but it's still leaking, the inlet valve may need replacement by a technician.
