If your refrigerator is leaking water onto the floor, start by checking the defrost drain since a clogged or frozen drain is the most common cause; thaw any ice and flush the drain with hot water to clear debris. If the drain is clear, inspect the door gasket next—tears, twists, or a poor seal will let humid air in and cause condensation that runs out the bottom. Also check the water tank assembly for hairline cracks, the water inlet valve for loose fittings or cracks, and the water filter housing and filter head for damaged housings or torn seals. These parts commonly cause fridge leaking water and refrigerator leaking water on floor problems when they fail. You don’t have to guess the right replacement: enter your model number on RepairClinic.com to find the exact part that fits your refrigerator, whether it’s a new gasket, inlet valve, water tank, or filter housing, and get repair instructions so you can fix the leak yourself.
01 - Clogged or Freezing Defrost Drain
If the defrost drain is frozen, the water will overflow the drain trough and drip down to the bottom of the compartment. This water can eventually leak onto the floor. Check the defrost drain to determine if it is clogged or frozen. If the defrost drain is frozen, thaw the ice. In addition, flush the drain with hot water to ensure that it is clear of debris.

02 - JC Penney Refrigerator Door Gasket
If a refrigerator is leaking water outside the appliance, it's possible a door gasket is damaged. A door gasket that does not form a proper seal to the refrigerator frame will allow warm humid air to enter the refrigerator or freezer compartment. This can create condensation which can then leak out the gap between the gasket and frame onto the floor. You should inspect the door gasket for any tears or twists and replace the gasket if necessary.

Inspect the water tank assembly for any leaks. Be aware that the leak may be very small and hard to find. If you discover a leak, replace the water tank. Do not attempt to repair the water tank—glue will not stick properly to the plastic of the tank.
The water inlet valve opens to supply water to the dispenser and icemaker. If the water inlet valve is cracked or has a loose fitting, water will leak from the valve. Inspect the water inlet valve for cracks, and make sure that it is tightly secured to the water supply line.
The water filter head might be cracked, or the seal may be torn or missing. Inspect the water filter housing for cracks. If you discover any cracks in the water filter housing, replace it.
