The short answer
On a 4w7z41 cabinet a puddle is a routing failure: meltwater that should have gone to the drain pan went somewhere else. The generic Amana answer opens with the supply line; on this platform the defrost drain is the first thing worth ruling out. A stain that returns in the same place every few days is diagnostic in itself.
What you actually observe
- A puddle at the front, under the doors — Mark the edge of the puddle so you can tell whether it is growing.
- Water at the back of the cabinet only — A leak that never reaches the front is usually behind the unit rather than inside it.
- A sheet of ice on the freezer floor — It will run as soon as the next defrost cycle melts it.
- A dried tide mark that keeps reappearing — The mark shows you where the water leaves the cabinet, which is not where it started.
Causes on the 4w7z41 listings, most likely first
- A blocked defrost drain tube — Meltwater from every defrost cycle has one route out, and when the tube ices or silts up the water backs into the cabinet and finds the door seal. A plugged drain gives you water inside the fridge first and on the floor second, usually under the crisper. This family is a single listing, so what is true of it is true of every unit carrying the badge.
- An ice maker fill or supply line fault — On the listings in this family that carry an ice maker, an overfilling valve or a weeping fill tube drops water inside the freezer and then out at the door seal.
- A door gasket letting warm air in — A door that is not sealing loads the evaporator with moisture, and every defrost cycle sends a larger slug of water down a drain built for less.
- A water filter head or cartridge leak — The head is under pressure whenever the supply is on, so a filter leak does not stop when the unit stops.
Check in this order, and why
- Find the drain hole at the base of the freezer wall — Warm water poured down it either runs through to the pan or it does not, and that is the whole test.
- Pull the cabinet out and look at the drain pan — You are looking for a crack, a warp, or a pan sitting off its rails, all of which leak only when the pan is loaded.
- Follow the supply line and the filter head dry — Wrap tissue at each fitting and come back in an hour; a weeping joint will find it faster than your eye will.
- Check the gasket for a section that has lost its grip — Only worth doing once the drain is known clear, because a seal fault shows up as a drain fault.
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. Water and a live appliance do not belong in the same job: dry the floor before you pull the cabinet out, because a wet floor and a heavy unit is how people get hurt. If the puddle reaches a wall outlet or an extension lead, kill the circuit at the breaker before you touch anything.

When to call a technician
The line on these models is whether the water is on the inside or the outside of the cabinet. Inside, it is a drain you can often reach; outside at the back, it is a fitting, a valve or a cracked pan and it needs the unit moved and held.
