What this usually is on unlabelled-stem cabinets
A leaking unlabelled-stem refrigerator sorts by where the water appears, and that single observation does most of the diagnosis. Water inside under the drawers is the defrost drain. Water on the floor at the front is the pan or the seal. Water at the back is the supply line if the cabinet has one.
What you actually observe
- A layer of ice under the bottom drawer — Water sitting in the channel and freezing where the air is coldest.
- Beads of water around the door frame or on the outside of the cabinet — Condensation rather than a leak — warm damp air meeting a cold surface.
- Water at the back, near the wall — On a cabinet with a water supply this is the line or its connection; without one it is the pan.
- NEAR MISS — water plus a cabinet that is no longer cold — That combination is a cooling fault with melt as its symptom, and the cooling article is the right place to start.
Causes in likelihood order on this model group
- Defrost drain blocked — Every cycle melts the frost off the evaporator and sends it down a small drain to a pan underneath. First on this family because it needs nothing taken apart — on a cabinet this size it is a look and a listen, and excluding it costs less than five minutes.
- Drain pan cracked, displaced or overflowing — The pan sits over the compressor so its heat can evaporate what collects. It ranks second on unlabelled-stem rather than first only because the cause above it is quicker to exclude, not because it is rarer.
- Cabinet not level, so condensate runs the wrong way — The channels inside a refrigerator rely on a slight tilt backwards to work. Ranked third here, because the two causes above it are both quicker to settle and more often the answer on a cabinet of this size.
The order of checks, and why it is this one
- Cyclic or continuous — Water that appears every day or two is defrost melt. Water that never stops is a supply, and a supply leak is the one to isolate before diagnosing anything else.
- Find the drain opening and check it takes water — It sits at the base of the compartment. A spoonful of warm water poured in should disappear; if it sits, the drain is the fault.
- Pull the cabinet out and look at the pan — It should sit square on its bracket and be damp rather than brimming. Note whether it is cracked or merely displaced.
- Check the cabinet sits square and slightly back — A spirit level across the top, or a door that swings open on its own, tells you in seconds.
Before you touch 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.

Where the owner fix stops
The line on this family is the panel: everything above it is owner work, and the moment a diagnosis needs the freezer rear panel off or a meter on a winding, it is a service call. Call immediately if the breaker trips again after a reset, if the cord or plug is warm to the touch, or if you see oil anywhere on the tubing.
