What this usually is on MCR cabinets
On an MCR cabinet the defrost drain is the first suspect for any water found inside, and it is also the one an owner can often clear. Before that, though, check the cabinet is level and that the door is closing, because both misdirect condensate and both are free to fix.
What this looks like at the cabinet
- Water running down the inside back wall onto a shelf — Melt leaving the evaporator area by the wrong route.
- The water appears in a cycle, a day or two apart — That rhythm is the defrost cycle, which places the fault firmly on the drain side.
- Water on the kitchen floor at the front of the cabinet — Either the pan has overflowed or cracked, or condensate is running down the outside of the door.
- It only leaks after the cabinet has been filled — A packed compartment blocks the channel that carries melt to the drain.
- 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.
What it usually turns out to be, in order
- Containers or packaging blocking the internal channel — The channel that carries melt to the drain runs along the back of the compartment, and a drawer pushed hard back or a box standing in the channel dams it. The water then finds the next lowest point, which is usually the front of the shelf below. It heads the list because the single model this page covers share it — nothing in the model table separates one code from another on this point.
- Door seal letting warm damp air in — A gasket that no longer seals admits room air, and that air gives up its moisture on the first cold surface it meets. The result is condensation inside the cabinet, sweating around the frame, and eventually more melt than the drain was designed to carry. Second here, and it is the rank most sensitive to how the cabinet is used — a unit opened all day sees this far sooner than one that is not.
- Drain pan cracked, displaced or overflowing — The pan sits over the compressor so its heat can evaporate what collects. A pan knocked off its bracket during a move, or cracked with age, empties onto the floor instead. Third on MCR: it is still something you can see rather than measure, but it takes the cabinet emptied or moved and the two above it do not.
What to check first, second, third
- Where to begin on this model group — The first checks are the ones that can be made with the cabinet standing where it is; moving it comes later and only if those are clean.
- Empty the bottom of the cabinet and look at the channel — It should be clear along its length and slope toward the drain opening.
- Test the seal with a strip of paper at four points — A strip that pulls out without resistance shows where the air is getting in, and that spot is usually where the water is worst.
- 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.
Before you touch anything
Safety
Isolate before you open: unplug the appliance or switch off its breaker, and remember that a capacitor can hold a charge after the power is off. Water and a live cabinet are the combination to avoid here — dry the floor before you start, and if the fault has already put water near the plug or the cord, isolate at the breaker rather than by pulling the plug out of a wet socket.

Where the owner fix stops
The honest limit is the rear panel. Behind it are components that need testing rather than looking at, and on a cabinet this size they sit close enough together that a probe in the wrong place breaks something that was working.
