The short answer
Water from a Craftsman refrigerator is usually water the cabinet made on purpose that then went the wrong way, rather than water escaping from a pipe. On this class the usual cause is the defrost drain blocked with ice or debris, with warm humid air condensing where a seal has failed next to rule out, and both are owner checks.
What you actually observe
- It leaks in summer and stays dry all winter — Humidity is doing the work, not a broken part.
- A sheet of ice across the floor of the freezer — Water that froze where it landed rather than where it was meant to go.
- NEAR MISS: the cabinet is warm as well as wet — Then cooling is the primary fault and the leak is a symptom of it, so read the cooling page first.
The causes, most likely first on this brand
- The defrost drain blocked with ice or debris — Every automatic-defrost cabinet melts frost on a schedule and sends that water down a small drain, and a drain plugged with ice or food debris sends it into the cabinet instead. Ranked first on a Craftsman unit: a garage cabinet swings through humid afternoons and cold nights, which loads the drain with far more water than a kitchen does.
- Warm humid air condensing where a seal has failed — A door seal that no longer closes draws room air in continuously, and that air gives up its moisture as water running down the inside of the liner. Ranked second here: a seal in an unheated room hardens faster and sweats harder.
- A drain pan cracked, overfull or out of its clips — Ranked third here: a pan on a sloping garage floor spills before it is full.
- A cabinet tilted so water runs forward instead of draining — Ranked fourth here: last, though a garage floor falls toward the door by design and that is worth checking.
Check in this order, and why this order
- Look for standing water under the crisper drawers — Water inside the cabinet before it is on the floor is the signature of a blocked drain and of nothing else.
- Shut a sheet of paper in the door and pull it out, working all four sides — A sheet that slides free marks a dead length of seal, and the corners give out before the faces do.
- Look under the front of the cabinet for the pan and whether it sits square — A wet trail from under the cabinet rather than from inside it points here first.
What an owner can safely check
- Pull the drawers, dry the trough and flush the drain hole with warm water from a bulb or a turkey baster — Never poke anything stiff down a drain that runs past the evaporator.
Tools: warm water, baster, clothAbout 30 min
- Wash the seal and its landing face with warm soapy water and dry both — Grease and crumbs hold a seal open far more often than a torn seal does.
Tools: cloth, mild detergentAbout 15 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the unit or switch off its breaker before any panel comes off or the cabinet is moved, and remember a capacitor can hold a charge after the power is off. Water on a floor beside a powered appliance is a shock risk, so deal with the power before the puddle. Close the supply shut-off before disturbing any plumbing fitting.
When to call a technician
Call once the drain, the pan and the seal are all clean and the water is still arriving, because a weeping valve or a split liner needs the cabinet stripped. Call sooner if the water is near an outlet or has reached flooring that will not dry, since that damage outruns the repair. Bear in mind when you decide that a garage unit lives outside the conditioned envelope, which changes what counts as normal before anything is diagnosed.

What this page does not cover
This page covers the Craftsman refrigerator as a class, not one family or model line. Drain routing, pan shape and filter head fittings all change from build to build and are deliberately not here. Where a family or model page exists for your unit, it is the more specific answer and the one to read first.
