Quick Answer
A fridge usually leaks for one of three reasons: a clogged defrost drain, a frozen or cracked water line, or an unlevel cabinet. Start at the defrost drain on the freezer floor, then work down the list before you call a local technician.
A refrigerator usually leaks water for one of three reasons: a clogged defrost drain, a frozen or cracked water-supply line, or a cabinet that is not level. The good news is that the most common cause is also the easiest to check. Here is how to find the source before you call anyone.
First, find where the water is actually coming from
Water on the floor does not always start at the floor. Pull the fridge out a few inches, look for drips at the back, check the freezer floor for a thin sheet of ice, and wipe everything dry so you can see where the water returns. Knowing the starting point saves a lot of guesswork.
Cause 1: A clogged defrost drain (most common)
Your fridge melts a little frost on a regular cycle, and that water is meant to run down a small drain into a pan underneath. When food debris or mineral scale clogs the drain, the water backs up and spills inside or onto the floor. Flushing the drain with warm water often clears it.
Quick tip: A thin layer of ice on the freezer floor almost always points to a clogged defrost drain.
Cause 2: A frozen or damaged water line
If your fridge has an ice maker or water dispenser, the supply line can crack or freeze and drip. Check the line and its connection at the back. ENERGY STAR notes that proper installation and airflow help a refrigerator run the way it should, which also reduces stress on these parts.
Cause 3: The fridge is not level
A refrigerator should tilt back very slightly so the doors close on their own and internal water drains the right way. If yours leans forward, adjust the front leveling legs and re-check.
When to stop and call a local pro
If the drain is clear, the lines look fine, and the unit is level but it still leaks, the cause may be the drain pan, the defrost system, or a failing valve.

Otherwise, the quickest path is to get connected with a local Fairfield technician who can diagnose it safely. You can learn more on our refrigerator repair page.
Frequently asked questions
Is a leaking refrigerator dangerous?
It is mainly a slip and water-damage risk. Still, clean up any standing water near an outlet right away.
Can I keep using it while it leaks?
Usually yes, as long as it still cools. Lay down a towel and have it checked before the leak gets worse.
