The short answer for the LTB models
On the Admiral LTB refrigerator models, water where it should not be leads somewhere the brand-generic article does not put first — a door seal letting warm humid air in. The brand-generic ordering opens instead with this: a blocked defrost drain. It moves down behind the lead here, because this family is a short run on a common stem, so its behaviour is consistent in a way the brand as a whole is not.
What you observe on these models
- Water running down the inside of the back wall — Melt from a defrost that is finding its own way down instead of reaching the channel.
- Water appears only every few hours, not continuously — That rhythm is the defrost cycle, and it is a strong clue on its own.
- A puddle at the back of the cabinet, on the outside — That is the drain pan overflowing or the pan itself, and it is a different half of the same story.
- NEAR MISS — the cabinet is also warm — Water plus warmth is usually one fault, and the cooling page leads on it.
Causes, most likely first on the LTB family
- A door seal letting warm humid air in — Every bit of humid air that gets in becomes condensation on a cold surface. Ranked first on the LTB models.
- A blocked defrost drain — Melt water from every defrost cycle has to run down a small channel and through a narrow tube. Second.
- A drain tube that has silted up over years — A long-serving cabinet has had every defrost cycle it will ever have run through the same small tube. Third.
- A cracked channel, a split tube or a failed liner — It is real, it needs the cabinet stripped to confirm, and every other cause here is cheaper and more common. Last, and that is the point of the order.
- Body: The spine for the LTB family records 3 model codes built on a common stem — a short run rather than a long one, which is why a single ordering covers all of them. Where this departs from the brand-generic ordering: the cause that moves up on these models is this one — a door seal letting warm humid air in — and the brand-generic lead moves down behind it.
Check in this order on the LTB models, and why
- Ask whether the water arrived suddenly or crept up over months — First: A slow arrival on a long-serving cabinet is the silted-drain signature, and it moves the drain to the front of the list.
- Do the paper test on the door seal at four points — Second: Seconds to do, and it decides whether the drain is failing or simply being overloaded.
- Put a spirit level on the top of the cabinet both ways — Third: Level is not just about the door swing here — it is what makes the drain channel work at all.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off and the fan can start without warning. The sealed system is not owner work: refrigerant is under pressure and the tubing is thin. While the cabinet is warm, a refrigerator holds food safely at 40 degrees Fahrenheit, which is 4 degrees Celsius, or below.

When to call a technician
Call when the drain has been cleared from inside and still backs up, when the water is coming from a fitting or a tube rather than from the channel, or when you can see water inside the cabinet walls rather than on them. Call immediately if water is reaching an outlet, a cord or the joinery structure around the cabinet — a wet electrical connection is not something to work around while you try one more thing. On the LTB models the line sits where the check stops being one you can make from outside the cabinet. Before booking, be ready to weigh the repair against the machine.
