The most common reasons include a clogged or frozen defrost drain, a cracked drain pan, a loose or damaged water supply line, or a faulty door seal causing excess condensation. While some of these issues are minor and easy to fix, others can lead to serious water damage if left untreated. In this article, we’ll break down each potential cause of refrigerator leaks, how to identify them, and when to call Clarksville Plumbing for expert help.
1. Clogged or Frozen Defrost Drain
One of the most common culprits of a leaking fridge is a clogged or frozen defrost drain. Most refrigerators have a defrost cycle that melts frost from the evaporator coils. This water usually flows through a drain tube into a pan underneath the fridge, where it evaporates. But when the drain is blocked or frozen, water can back up and leak out onto the floor.
What causes the drain to clog?
Over time, food particles, grease, or even mold can clog the drain. In colder parts of the fridge or freezer, the water can also freeze in the line, leading to overflow during defrost cycles.
How to fix it:
If you’re comfortable doing some light maintenance, you can try clearing the drain with hot water and a turkey baster. Otherwise, it’s a smart idea to call Clarksville Plumbing. We can safely flush the drain and ensure your fridge drains properly again.
2. Damaged or Disconnected Water Line
Many modern refrigerators come with built-in water dispensers and ice makers, which are connected to your home’s plumbing via a small water supply line. If this line becomes cracked, loose, or disconnected, it can leak water behind or beneath your refrigerator.
Signs of a leaking water line:
- Water pooling behind the fridge
- Reduced or no water flow to the dispenser
- Ice maker not functioning properly
What to do:
Pull the fridge away from the wall and inspect the line. If you see visible damage or leaks, turn off the water supply to the fridge and contact a plumber. At Clarksville Plumbing, we can repair or replace damaged water lines and prevent future leaks.
3. Cracked Drain Pan
Your fridge has a drain pan underneath that catches water during the defrost cycle. While the water usually evaporates, a cracked or misaligned pan will allow water to spill onto your floor.
Why drain pans crack:
- Age and wear
- Accidental impact while cleaning or moving the fridge
- Warping from heat or cold fluctuations
Solution:
You can remove and inspect the drain pan yourself, but be cautious. If you find cracks or damage, it needs to be replaced. Clarksville Plumbing can inspect your fridge setup and recommend or install a proper replacement.
4. Door Seal Isn’t Closing Properly
If your refrigerator door isn’t sealing tightly, warm air can enter the fridge, leading to excess condensation. That condensation can accumulate inside the fridge and eventually leak onto the floor.
Signs of a bad seal:
- Moisture buildup inside the fridge
- The door feels loose or doesn’t close all the way
- The fridge motor runs constantly to stay cool
How to check:
Run your hand along the edge of the closed door to feel for escaping cold air. Clean the gasket with warm, soapy water and inspect for cracks or gaps. If the seal is damaged, it should be replaced to keep the temperature consistent and prevent moisture buildup.
5. Excessive Condensation or Humidity
During warm and humid seasons, especially in Maryland’s climate, your refrigerator can struggle with excess condensation. If the condensation has nowhere to go—or if the drain system is malfunctioning—you may notice water leaking inside or outside the unit.
What can you do?
Check the humidity settings and make sure the fridge doors aren’t left open for extended periods. If the leak persists, there may be an underlying plumbing or drainage issue that needs attention.
6. Ice Maker or Filter Housing Leak
Another sneaky source of leaks is a faulty ice maker or water filter housing. Water filters should be changed every six months, and improperly installed or cracked filters can leak. The housing itself may also wear out over time.
How to detect this leak:
- Check for water beneath the filter area
- Look for dripping from inside the refrigerator compartment
- Listen for hissing or dripping sounds
Replacing a worn filter is easy, but if the housing is cracked or leaking, it’s best to call a plumbing professional. Clarksville Plumbing can assess the issue and ensure your fridge is safe to use.
7. Tilted or Uneven Fridge
Believe it or not, your refrigerator needs to be properly leveled for the defrost water to flow correctly into the drain pan. A fridge that tilts forward or sideways can cause water to accumulate in unwanted areas and eventually leak out.
How to level your fridge:
Use a carpenter’s level to check the fridge. The front should be slightly higher than the back to allow gravity to pull water toward the drain pan. You can adjust the leveling feet under the fridge if necessary.
