What this means on these models
On the 4k7z10 refrigerator this symptom is usually the plumbing behind the machine, because the water that gets to this cabinet passes through fittings that were made up once and never looked at again. The 4k7z10 family is a single model number, so the parts list behind every check below is unambiguous.
What you observe on these models
- The leak follows the weather — Worse on humid days and gone in winter is condensation getting in, not water getting out.
- A damp patch that appeared within a day of a filter change — One joint was opened recently, and that is the joint worth looking at first.
- Frost on the freezer rear wall alongside the water — Two symptoms with one cause: airflow blocked, drain frozen, water finding another way out.
- Water under the crisper drawers with a dry floor outside — Water inside the cabinet and none behind it means the drain path, not the supply.
- NEAR MISS — water only on top of the fresh food, never on the floor — Condensation on food and shelves with a dry floor is a door-left-ajar or over-full cabinet problem, and no part needs replacing.
Causes, most likely first on the 4k7z10 family
- Supply line, shut-off valve or compression fitting weeping — Ranked first on this family. It is the version of this fault that has nothing to do with the refrigerator at all, which is why it is worth eliminating early.
- Drain pan cracked, displaced or overflowing — Next, and close behind it. A cracked pan produces the same puddle and is the reason a leak can appear months after a house move with nothing else having changed.
- Door seal letting humid air in and condensing it — Next after those two. A gasket that has taken a set, or a door dropped on its hinge, produces it without any plumbing being involved at all.
- Cabinet out of level, tipping condensate the wrong way — Fourth, and the least likely of the four. Tipped forward, or sitting on a floor that has moved, the channel that should feed the drain feeds the door instead.
- Body: A brand-generic article on this symptom starts with the blocked defrost drain. Here the supply line moves ahead of it, because a single-model family leaves nothing to average across, so the ranking can follow what this one platform actually does.
What to check first, and why that order
- Dry the floor behind the unit and lay a sheet of paper under each fitting — A damp patch that reappears on the paper within an hour names the fitting without any dismantling.
- Slide the unit out and look at the pan sitting over the compressor — Water in the pan is normal.
- Run a hand around the door line for a cold draught, then paper-test the seal — A draught you can feel, or paper that slides out with no drag, names the gasket and the hinge together.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel, and before reaching behind the cabinet to dry a fitting — a capacitor can hold a charge after the power is off. Water on a floor next to a plugged-in appliance is an electrical hazard first and a plumbing problem second, so isolate before you mop.

When this becomes a service call
Anything that needs the rear panel off, the liner opened or the sealed side touched is a service visit on these models. Call once the drain, the pan and the visible fittings are clean and dry and the water still returns, because the remaining causes sit behind the liner.
