The short answer
A leak on a 4w3in62 refrigerator usually begins as frost you never saw. Where the brand-generic article ranks the water valve first because it must cover plumbed and unplumbed models together, this one ranks the drain path first. Mop the floor and mark the spot before you move anything.
What you actually observe
- A puddle at the front, under the doors — Mark the edge of the puddle so you can tell whether it is growing.
- A sheet of ice on the freezer floor — Water that freezes before it reaches the drain builds a slab under the bottom basket.
- Drips at the dispenser or under the filter head — Wipe it dry and watch it for a minute.
- NEAR MISS — water only when the ice bin is filled — Check whether the bin itself is cracked before going further.
Causes on the 4w3in62 listings, most likely first
- An ice maker fill or supply line fault — On the listings in this family that carry an ice maker, an overfilling valve or a weeping fill tube drops water inside the freezer and then out at the door seal. Ice on the freezer floor and a puddle at the same time points here. The short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- A cracked or displaced drain pan — Pans warp with age and with the heat of the condenser above them, and a warped pan spills before it is full.
- A cabinet out of level — Out of level, the drain trough spills at its low corner instead of draining, and the water tracks along the liner to the door.
- Condensate overwhelming the drain in humid weather — This sits last because it is a condition rather than a fault, and because every cause above it has to be ruled out before it is a fair conclusion.
Check in this order, and why
- Dry everything and find where the water starts — Inside the cabinet, at the back, or under the doors — those three answers point at three different sets of causes. Do this before you move the unit, because moving it destroys the evidence.
- Find the drain hole at the base of the freezer wall — Warm water poured down it either runs through to the pan or it does not, and that is the whole test. Do not push anything sharp into it.
- Pull the cabinet out and look at the drain pan — You are looking for a crack, a warp, or a pan sitting off its rails, all of which leak only when the pan is loaded. Check the tube actually ends over the pan.
- Check the gasket for a section that has lost its grip — Only worth doing once the drain is known clear, because a seal fault shows up as a drain fault. Four points a door, not one.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Water and a live appliance do not belong in the same job: dry the floor before you pull the cabinet out, because a wet floor and a heavy unit is how people get hurt.

When to call a technician
The line on these models is whether the water is on the inside or the outside of the cabinet. Inside, it is a drain you can often reach; outside at the back, it is a fitting, a valve or a cracked pan and it needs the unit moved and held.
