The Short Answer
Inside under the crispers means a blocked defrost drain. On the floor behind the unit means the water line or inlet valve. At the front, suspect the drain pan or an unlevel install. Match your puddle to the table below — and if the source involves the water supply, close the shut-off valve behind the fridge before anything else.
Find the Leak by Its Location
Refrigerator leaks are unusually honest: each source drops its water in a different place. Before moving the fridge or calling anyone, note exactly where the water collects.
| Where the Water Is | Likely Source | What to Do |
|---|---|---|
| Pooling under the crisper drawers | Blocked defrost drain — the #1 fridge leak by a wide margin | Flush the drain hole with warm water; persistent clogs need a technician |
| On the floor, toward the back | Split water-supply line or a failing inlet valve (ice maker and dispenser models) | Shut the supply valve behind the fridge, then call — water damage escalates fast |
| On the floor, at the front | Cracked or overflowing drain pan, or the fridge sitting out of level | Level check is DIY; a cracked pan is a quick professional swap |
| Dripping inside from the ceiling of the compartment | Ice dam above from a defrost fault melting through | Professional — the defrost system needs testing, not just the ice removed |
| Around the door edges | Warm, humid air condensing past a worn gasket | Gasket replacement restores the seal and stops the sweating |
The Defrost Drain: Champion of Fridge Leaks
Every frost-free refrigerator melts its own ice on a schedule, and that meltwater exits through a small drain at the back of the compartment into a pan below, where it evaporates. Food debris or a plug of ice in that drain sends the water forward instead — collecting under the crisper drawers and eventually onto your kitchen floor. Flushing the drain hole with warm water clears many clogs; a drain that re-blocks within weeks usually has an icing problem upstream that needs a technician's attention.
Water Lines Deserve Respect
Ice maker and dispenser models carry a pressurized quarter-inch water line at all times. A pinhole split or a tired inlet valve does not leak dramatically — it seeps, quietly, into flooring and subfloor. If the puddle is behind the fridge and the line or valve is suspect, shut the supply off and treat it as urgent: hardwood and laminate lose the race against slow water every time.
“A fridge leak is rarely an expensive repair — but the floor beneath it can be an expensive delay.”

When a Leak Is Worth a Professional Visit
Recurring drain clogs, any supply-line or valve suspicion, ice dams inside the compartment, and gasket condensation all justify the call — because the repair is modest and the flooring it protects is not. Our Sherwood Park refrigerator repair technicians trace leaks to the source and fix the cause, not the symptom.
