The short answer
On the Amana 4w8g70 refrigerator family, water where it should not be points at the drain path, because everything a frost-free cabinet melts has to leave by one trough and that trough is the first thing to silt up. The brand-generic article leads the same way, but the places behind it are not the same here, and that is where a visit is won or lost.
What you observe on these models
- Water pooling under the crisper drawers — The clearest single tell there is, and it appears inside long before it appears on the floor.
- A stain on the floor that reappears at the same spot — A repeatable location is worth more than any single observation about volume.
- Water running down the inside of the liner — Condensation, which stays inside the cabinet and leaves the floor dry.
- NEAR MISS — ice on the shelves but no free water — That is a seal or a door-ajar problem rather than a leak.
Causes, most likely first on this family
- Defrost drain blocked with ice or sludge — First on this platform. Meltwater from each defrost has exactly one way out. When the drain trough freezes or silts up, the water backs up under the crisper drawers and finds the floor by the shortest route.
- Drain pan cracked, displaced or overflowing — Second on these models. The pan under the cabinet is meant to evaporate what the drain delivers. Once it is cracked or knocked out of position by a move, the same water that used to disappear now arrives on the floor.
- Door seal letting warm air in, and the condensation that follows — Third, and less common than the two above. Humid room air meeting cold surfaces condenses, and a gasket that has lost its set at one corner lets in enough to run. In a humid month it can be the whole story.
- Internal water tank or tubing split — Last, and the only one of the four here that is not owner work. The reservoir in the door or behind the liner is soft tubing, and a split there leaks only while the line is pressurised. It is the hardest of these to see and the easiest to misread as a drain.
Check in this order, and why
- Pull the crisper drawers and look for water under them — Start here. Water standing in the bottom of the fresh-food liner is the drain answer, and it appears there before it appears on the floor.
- Look at the pan under the cabinet — Then this. It should be damp, not full and not displaced. A cracked or shifted pan explains a floor leak with a healthy drain.
- Look for water inside the cabinet with the floor dry — Third. Condensation stays inside. A dry floor with a wet liner is the strongest single clue on this list.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Do not thaw an iced evaporator with a flame or a high-heat gun. Warm air and patience do the same job without melting the liner or starting a fire.

When to call a technician
Call once the drain, the filter head and the level are all clean, because what is left is behind the liner or inside a pressurised joint. Call immediately if water is reaching an outlet, an extension lead or the floor under another appliance. That is an electrical question before it is a plumbing one.
