What this usually is on OR cabinets
A leak on the OR family is a routing problem. Every refrigerator produces water; the drain, the pan and the seal are the three things that decide where it goes, and a fault in any of them puts it on your floor instead. Isolate the machine before you work on the floor around it.
The observable symptoms
- 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.
- 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.
- A musty smell with damp at the base of the cabinet — Standing water in a channel that has not drained for some time.
- An old stain on the floor with no visible water now — An intermittent leak on the defrost cycle rather than a continuous one.
- 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.
The ranked causes for this family
- Defrost drain blocked — Every cycle melts the frost off the evaporator and sends it down a small drain to a pan underneath. Ranked first here: it is both the commonest cause of this complaint on compact refrigeration and the cheapest to rule out, which is the same reason it belongs before anything requiring a panel.
- Cabinet not level, so condensate runs the wrong way — The channels inside a refrigerator rely on a slight tilt backwards to work. Ranked second because it explains the cases the first cause does not, and because on this family the two are checked from the same side of the cabinet.
- Drain pan cracked, displaced or overflowing — The pan sits over the compressor so its heat can evaporate what collects. Third: real, but it usually announces itself with something the first two causes do not produce, so the earlier checks will have already pointed at it.
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.
- 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.
- 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.
- 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.
Isolate the machine first
Safety
Isolate the machine first: unplug it, or switch off its breaker if the plug is behind the cabinet. A capacitor can hold a charge after the power is off, so wait before touching any terminal. Sealed-system work is a separate category — the tubing carries refrigerant under pressure, cutting or unbrazing it is licensed work, and nothing on this page asks you to open it.

When this stops being owner work
Book a technician once the checks above come back clean, and book one straight away if any of three things is true: the compressor is hot and silent, the breaker will not hold, or there is oil at a joint. Those three each mean the fault has moved past the part of the machine an owner can reach.
