The answer in three sentences
An Admiral LTB cabinet is meant to produce water; a leak is that water taking a route it was not given, and the route is written in where the puddle sits. Defrost meltwater is normal and there is a drain and a tray to take it away. Almost every leak is that path closing up, or a supply line that has let go — and the two behave so differently that finding the water tells you which one you have. The table below names three models under this family key. They are near enough alike that the fault presents the same way on each; the divergence is in part numbers rather than in how you find it.
What you observe on these models
- Water pooling inside, under the crisper drawers — That is defrost meltwater that has not reached the drain, so it has run forward into the cabinet instead.
- Water on the floor at the front of the cabinet — It has come over the front lip, which means the inside pool has been building for a while.
- Water at the back, near the wall — That is the supply line, the inlet valve or an overflowing drain tray, and it is a different repair entirely.
- Ice forming in the bottom of the freezer or under the drawers — The drain is frozen rather than merely blocked, and the water is freezing where it stands.
- NEAR MISS — water only after a hot, humid day with the door opened often — Condensation on the seals and shelves is normal in that weather and is not a leak.
Causes, most likely first on the LTB family
- The water supply line, its fitting or the inlet valve — This is the only part under mains pressure, so when it goes the volume is far larger than anything the defrost system can produce, and it goes at the back where nobody looks. All three models under the LTB key are built the same way here, so an ordering that fits one of them fits the rest.
- A blocked or frozen defrost drain — It is a narrow passage at the coldest point of the machine, carrying water that arrives with debris in it, so it is the part of the water path most likely to close up — and it does so gradually.
- Door seals letting warm air in — Warm, moist air condensing on cold surfaces produces standing water without anything having failed, and a seal that has taken a set no longer grips in the corners.
- The ice maker fill tube or its mould overflowing — A fill that overshoots or a tube that has iced and split puts water into the freezer floor rather than into the mould, and it only leaks when the cabinet calls for ice.
Check in this order on these models, and why
- Pull the cabinet out and check the supply fitting and the valve body are dry — Checked early whenever the water is at the back, because a pressurised leak does not wait.
- Find where the water sits inside and work back to the drain outlet — First, because water inside the cabinet nearly always means this and nothing else.
- Close the door on a sheet of paper at several points and see if it pulls free — Free, fast, and it explains water that appears only in warm weather.

Isolate it first
Safety
Isolate the cabinet at its breaker, or draw the plug, before any panel is disturbed — stored charge can remain in a capacitor once the supply is gone. Never chip at evaporator ice with a tool or warm it with a flame: the pipework beneath is thin enough to open under both. Treat the sealed circuit as out of bounds, since recovering refrigerant is licensed work. Clear the shelves before the cabinet is walked out, because a loaded unit carries its weight high and is heavier than it looks. The freezer door switch stays exactly as the factory wired it.
The line between an owner check and a service call
Call a technician if the drain has been cleared and the water returns, or the moment the leak proves to be on the supply side rather than the defrost side. Call at once if water is reaching an outlet, a floor void or a room below. The appliance repair is rarely the expensive part of a refrigerator leak; what the water reached while nobody knew almost always is.
