The short answer
On a True Manufacturing Company, Inc. refrigerator, a refrigerator makes water on purpose — every defrost cycle produces it — so a leak is almost always a drainage problem rather than a plumbing one. Where the water appears tells you which: inside under the crispers means the drain, on the floor at the front means the drain has overflowed, and behind the cabinet means the supply. Paperwork under the full company name usually belongs to a cabinet bought through a dealer for a working kitchen, so this page is written for a unit that runs all day.
What you are actually seeing
- A puddle appearing at the front of the cabinet on the floor — The inside trough has overflowed and is running out under the door.
- Droplets on the inside of the cabinet after each opening — Condensation from room air, not a leak.
- NEAR MISS — water plus a cabinet that is warming — Deal with cooling first: a failed defrost produces both at once.
Causes, most likely first on this refrigerator
- The defrost drain has stopped draining — Ranked first on True Manufacturing Company, Inc.: a cabinet opened constantly makes much more defrost water than a domestic one, so any restriction in the drain shows up quickly. On this one, remember that a cabinet recorded under the full company name is usually a dealer-supplied working unit, so assume long hours.
- Drain pan overflowing, cracked, or the cabinet tilted so water runs the wrong way — Second: it is the last stop in the water path, and a cabinet that has been moved recently is usually no longer sitting as it was.
- A slow leak at the supply connection — Third: it is the one cause here that produces water on the floor with the cabinet perfectly dry inside.
- Ice maker overfilling, or the fill tube spilling past the mould — Ranked last here, deliberately: it produces a sheet of ice under the bin and then water on the floor when that sheet melts, which is a very specific signature.
Check in this order, and why
- First — look for water or ice under the crisper drawers and at the back of the compartment — Water pooling inside the cabinet is a drain fault until proven otherwise, and nothing else looks like it.
- Then — check the cabinet is level with a slight backward tilt, and look at the tray — A forward tilt turns the whole drainage system round, and it is the cheapest thing on this page to correct.
- Only then — look for a slab of ice under or behind the ice bin — Ice where ice should not be tells you the fill is overshooting rather than that the cabinet is leaking, which is why it comes after everything above it.
What an owner can safely check
- Find the drain outlet at the back of the compartment and flush it — Take the drawers out, find the trough and its outlet, and ease warm water down it until it runs away freely.
Tools: warm water, turkey baster or syringeAbout 25 min
- Inspect the supply connection and dry it, then check again an hour later — Dry everything, put a sheet of paper under the joint and come back. A wet sheet names the joint without any tools.
Tools: torch, paper, clothAbout 20 min
- STOP at the first step that needs a meter on live terminals — That is where an owner check ends and a service visit begins, and nothing above this line needs one.
Before you open anything
Safety
Water and electricity share this space. Unplug the cabinet or switch its breaker off before you mop up anything under or behind it, and before any panel comes off. Do not run an extension lead across a wet floor to keep the unit going.
When it stops being an owner job
Call when the drain will not clear with warm water, when the leak is behind the cabinet at a plumbing joint you cannot reach or re-make, or when water keeps arriving after the ice maker has been off for a day. Call immediately if water is reaching an electrical connection, if the floor covering is lifting, or if there is water plus a rise in cabinet temperature — that pair means the defrost system, and it will not fix itself.

What this page does not cover
This page is written for the True Manufacturing Company, Inc. refrigerator as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
