The short answer
On a forced-air Accucold the usual cause is a blocked or frozen defrost drain: the trough backs up and puts water under the shelves. Levelling and the drain pan behind are the next two. All are owner checks needing nothing but warm water and a level. Only a split trough or a liner fault needs a technician, and both are uncommon.
What you observe
- Water pooling in the base on a regular cycle — Cyclic timing is the defrost drain's signature.
- Layered ice at the back of the compartment — The drain has frozen rather than merely clogged.
- A wet floor behind with a dry interior — The pan on the compressor is cracked or displaced.
- The cabinet rocks or leans forward — A short trough with no fall cannot drain.
- NEAR MISS — beads on the shelves only — Condensation from door use, not a leak.
Causes, most likely first on this class
- Defrost drain blocked or frozen — First on a forced-air compact because the drain is narrow, it sits in the coldest part of the air path, and any debris that reaches it seeds an ice plug that each cycle grows rather than clears.
- Cabinet not level, so the trough cannot drain — Second: there is very little fall to work with on a small unit, so a rug, a worn floor or a mis-set foot is enough to strand water inside.
- Drain pan cracked or off its rails — Third, and the answer whenever the floor is wet and the inside is dry. Compact cabinets are moved often, which is how pans get displaced.
- Door gasket admitting humid air — Last. It produces heavy condensation that overwhelms the drain rather than blocking it, so it feeds the causes above.
Check in this order, and why
- Decide whether the water is beaded or pooled — One look separates condensation from a drain fault.
- Check the cabinet is level and does not rock — Free, and a genuine cause on a short trough.
- Pour warm water into the drain hole — Confirms or clears a blockage without tools.
- Look at the pan on the compressor — Left until here because it needs the cabinet moved.
What an owner can safely check
- Dry the interior and note when water returns — A regular return matches the defrost cycle.
Tools: clothAbout 15 min
- Level the cabinet with a slight tilt back — It should not rock and the door should close on its own.
Tools: spirit levelAbout 15 min
- Pour warm water slowly into the drain hole — It should run away. Backing up confirms a blockage.
Tools: jug of warm waterAbout 15 min
- Unplug and ease the cabinet out to inspect the pan — Seat it squarely; replace it if cracked.
About 20 min
- STOP HERE if the trough or liner is split — That is structural and needs a technician.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or working behind it; a capacitor can hold a charge after the power is off, and the compressor runs hot enough to burn after a cycle. Never clear a frozen drain with a wire, a screwdriver or a heat gun — the liner punctures and melts easily, and there is tubing behind it. Dry the floor before restoring power.
When to call a technician
Call once the cabinet is level, the drain runs freely, the pan is intact and water still appears on a cycle — the trough or the liner is then the answer. Call sooner if the drain will not clear with warm water, because repeated attempts push debris further in and a drain that refreezes points at the defrost system. Call immediately if the cabinet is also failing to hold temperature.

What this page does not cover
This page is written for the brand and the appliance class, not for one family or model line. Where a family- or model-specific page exists for your unit, that page is the more specific answer and you should start there. Deliberately absent: drain and pan part identifiers, levelling tolerances, defrost intervals and clearance dimensions, all of which differ between the general-purpose, laboratory and under-counter families.
