The short answer
The ACFM roster spans several capacity cores rather than one, so the cabinets it covers differ in how far air and meltwater have to travel inside them, and it is wide enough to span several service generations, so the full code matters more here than on a narrow line. Where the water shows up narrows the cause before any panel comes off. Under the crispers and out of the door is a blocked defrost drain; at the back is the pan or the supply; inside along the seal is condensation from air that should not be getting in.
What you observe on these models
- Water under the crispers and then out of the door — The classic blocked defrost drain. Meltwater backs up in the compartment floor and takes the shortest route out once it has nowhere else to go.
- A wet patch at the back or under the cabinet — The drip pan, the drain outlet, or a supply fitting. It is worth distinguishing before opening anything, because one is meltwater and one is not.
- Ice forming in a sheet on the compartment floor — A drain that has iced over completely. The water freezes where it stands instead of draining, and the sheet grows with every defrost.
- Condensation or ice along the door seal — Warm humid room air arriving where the seal is not closing. The frost pattern marks the leak, which makes it the most self-diagnosing symptom here.
Causes, most likely first on the ACFM line
- Defrost drain blocked or iced — Ranked first on this roster: it is progressive: the first block produces a small overflow and each defrost after that adds to the ice rather than clearing it.
- Door seal admitting humid air — Ranked second on this roster: a seal that has taken a set lets room air in continuously, that moisture condenses on the coldest surface it reaches, and eventually it runs out at the same place it came in.
- Supply line, filter housing or inlet fitting leaking — It ranks third here because it is the only cause here that can put down more water than the cabinet makes, and because it does real damage while it is ignored.
- A split drain line or damaged liner inside the insulation — Ranked last on this roster: it is the one result that turns a leak into a repair-or-replace decision.
- Body: Where this ranking departs from the brand-generic order is door seal admitting humid air, which moves up on the ACFM line because the roster is wide and spans several service generations, so the order is weighted to what recurs across all of its cabinets rather than to any one of them.
Check in this order, and why
- Confirm your own code before ordering anything — This roster is wide enough to span several service generations, so a part that fits one cabinet on it may not fit its neighbour. The plate settles it.
- Find the drain opening in the compartment floor and test it — Pour a small amount of warm water into it. If it backs up rather than draining away, the route is blocked.
- Run the paper test around the whole door perimeter — Anywhere the paper slides out freely is admitting air, and that is where the condensation is forming.
- Close the shut-off and look at every fitting — Check the filter housing, the inlet and the visible run of the line. A fitting wet on top of the cabinet floor is not meltwater.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and treat what is behind it as live until proved otherwise. Deal with the floor before the cabinet: a wet floor beside a plugged-in appliance is a shock risk and a slip risk together. Close the water shut-off before disturbing a fitting, because a line under pressure behind a heavy cabinet is hard to stop once it starts, and get help before moving a full cabinet.

When to call a technician
Owner territory here is wide. The drain, the seal, the level, the pan, the visible supply run and the ice maker are all reachable with no tool and no panel. It ends where the drain route disappears into the insulation, and at any fitting you are not confident re-making.
