Refrigerator Leaking Water? 8 Causes to Check in Fargo
You find a puddle in front of the fridge, water under the crisper drawers, or ice building up on the freezer floor. A leaking refrigerator can damage floors fast, but most leaks come from a short list of causes, and a few are easy to fix yourself. Here’s what to check, and when it’s time to call for repair.
Quick Answer: Most refrigerator leaks come from a clogged defrost drain, a cracked or loose water supply line, a water filter that isn’t seated correctly, or a failing water inlet valve. Water inside the fridge usually points to the defrost drain. Water behind or under the fridge usually points to the water line or inlet valve.
First: Protect the Floor and Stay Safe
Wipe up the water and put towels down. If water is near the back of the fridge or an outlet, unplug the refrigerator before you move it. If the leak is from the water line, shut off the water valve that feeds the fridge, often under the kitchen sink or in the basement.
1. The Defrost Drain Is Clogged
This is the most common cause of water inside the fridge. During defrost, melted frost runs down a small drain at the back of the freezer or fresh food section. Food bits or ice can block it, so the water overflows and collects under the crisper drawers or freezes on the freezer floor.
Fix: find the drain hole, then flush it slowly with warm water using a turkey baster. If it’s frozen, a little warm water over time will thaw it. If the drain keeps freezing, the defrost heater or another defrost part may be failing.
2. The Drain Pan Is Cracked or Out of Place
Defrost water drains into a shallow pan under the fridge, where it evaporates. If the pan is cracked or shifted after the fridge was moved, water ends up on the floor. Remove the lower kick plate to check it.
3. The Water Supply Line Is Cracked or Loose
Fridges with an ice maker or water dispenser have a supply line in back. Thin plastic lines crack with age, and connections loosen when the fridge is pulled out. Older saddle valves are also a common leak point. Look along the line and at both ends for drips.
4. The Water Filter Isn’t Seated
A filter that isn’t fully locked in, the wrong filter model, or a cracked filter housing can leak inside the fridge or behind the grille. Remove the filter, check the seals and reinstall it until it clicks. Fargo’s moderately hard to hard water can also clog filters faster, so replace them on schedule.
5. The Water Inlet Valve Is Leaking
The inlet valve at the back of the fridge controls water to the ice maker and dispenser. A cracked valve body or worn seal can drip behind the fridge. Mineral buildup can also keep the valve from closing fully, which can overfill the ice maker.
6. The Ice Maker Fill Tube Is Frozen or Overflowing
If the fill tube freezes, water can spill into the freezer instead of the ice mold and freeze on the floor of the compartment. An ice maker that overflows or makes oversized, fused cubes can also point to an inlet valve problem. See our ice maker repair page for more.
7. The Door Seal Is Letting in Warm Air
A worn or dirty door gasket lets humid air in. That air turns into condensation and extra frost, which melts into more water than the drain can handle. Clean the gaskets with warm soapy water and check for gaps by closing the door on a dollar bill. If it pulls out easily, the seal is weak.
8. The Fridge Isn’t Level
Most refrigerators should tilt slightly back so the doors close on their own and water flows toward the drain. If the fridge leans forward, water can run out the front. Adjust the front leveling feet.
What You Can Safely Do Yourself
- Flush the defrost drain with warm water.
- Reseat or replace the water filter.
- Tighten a loose water line connection and look for cracks.
- Clean the door gaskets.
- Level the refrigerator.
Replacing a water inlet valve, defrost parts or a drain pan means pulling the fridge out and removing panels. If you’re not comfortable with that, it’s a good time to call.

Why is there water under the crisper drawers in my fridge?
A clogged defrost drain is the most likely cause. The melted frost can’t reach the drain pan, so it pools under the drawers. Flushing the drain with warm water usually fixes it.
Is a leaking refrigerator dangerous?
The bigger risk is water damage to floors and cabinets. If water reaches an outlet or the back of the fridge, unplug it and shut off the water supply before cleaning up.
Is a leaking refrigerator worth repairing?
Usually, yes. Most leaks are drains, water lines, filters or inlet valves, which cost far less than a new refrigerator. If the fridge is older and also has cooling problems, a repair-or-replace check makes sense.
