The short answer
On the Amana 4w5ij90 refrigerator family, water where it should not be points at a thaw rather than a fault, because the single largest group of one-off leaks follows a door left ajar or a power cut nobody noticed. The brand-generic article puts a blocked defrost drain at the top of this symptom; on this platform it sits second, behind causes that are quicker to rule out.
What you observe on these models
- Water appearing once and never returning — A one-off thaw behaves completely differently from a fault and needs no part.
- Water pooling under the crisper drawers — The clearest single tell there is, and it appears inside long before it appears on the floor.
- Water running down the inside of the liner — Condensation, which stays inside the cabinet and leaves the floor dry.
- NEAR MISS — the cabinet is warm as well as wet — Then the leak is a symptom of the cooling fault and that page comes first.
Causes, most likely first on this family
- Frost melting after a door was left open or after an outage — First on this platform. This is a one-off leak that arrives with a full freezer thaw and does not repeat. It matters because it looks identical to a drain fault for the first day and then behaves completely differently.
- Defrost drain blocked with ice or sludge — Second on these models. 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.
- 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.
- Drain pan cracked, displaced or overflowing — Fourth, and the least common of the four here. 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.
Check in this order, and why
- Ask whether a door was left open or the power went off — Start here. A one-off leak with a full-freezer thaw behind it does not repeat and needs no part at all.
- Pull the crisper drawers and look for water under them — Then this. 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 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.

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.
