The short answer
A blocked defrost drain is the most common leak in any cabinet with a freezer above or below the fresh-food compartment. It shows up as water under the crisper drawers or a spreading pool under the unit, and it is often clearable without a part. Every step below removes a whole class of fault rather than a single part. Start at the cheapest check and work down.
What the appliance is doing
- A spreading pool on the floor at the front — Overflow from the interior finding its way out at the door line.
- Water at the back of the cabinet — Supply line, valve connection or a drip tray that has cracked or overflowed.
- Ice building in the bottom of the freezer — A drain that has frozen closed rather than simply blocked.
- NEAR MISS: water only after a hot day with heavy use — Ordinary condensation load, especially in a humid room, and not a fault.
Ranked causes
- Drip tray cracked, displaced or overflowing — Most likely here. It leads on a compact cabinet because the evaporation tray sits directly over the compressor and is easily knocked out of place when the unit is moved. The tray under the cabinet evaporates condensate. Cracked or out of position, it simply delivers that water to the floor instead.
- Door seal admitting humid air — Next most likely. Warm air in, condensation out.
- Cabinet leaning forward — Third in the order. Condensate runs the wrong way along a channel designed to drain backwards.
- Water supply line or fitting leaking — Then this one. A compression fitting behind the cabinet or a pierced line. This is the leak that damages floors, so it is the one to rule out early.
- Body: The order below is what makes this page worth reading. It is a ranking rather than a measurement, and it carries no numbers because no fact bundle supports any.
The order of checks
- Dry everything and note exactly where water returns first — Inside under the drawers, at the back, or on the floor at the front: three places, three different faults.
- Pull the cabinet out and look at the supply line and its fittings — Do this early, because a supply leak is the one that damages the room.
- Check the drip tray above the compressor — Cracked, dry or displaced trays are visible at a glance.
- Body: The order below is a locating procedure. Where the water is answers the question faster than any part inspection.
The checks you can do yourself
- Dry the cabinet base and watch it for a day — A dated note of where water reappears is worth more than any inspection.
Tools: cloth
- Clear the defrost drain from inside the compartment with warm water — Pour gently into the drain hole and watch for it to run through.
Tools: warm water, turkey baster
- Check and reseat the water filter — Remove it, inspect the seal, refit it firmly and dry the housing.
- STOP before removing a rear evaporator cover or disturbing a plumbed fitting under pressure — Close the water supply first and leave the rest to a technician.
Before you touch it
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 on a kitchen floor next to a powered appliance is a shock and a slip hazard: dry it before you work, and isolate the cabinet before reaching behind it.
When to call a technician
Call when the drain will not clear with warm water, when water returns from behind the cabinet, or when any plumbed fitting is wet. A supply leak is urgent because the damage is to the room rather than to the appliance, and it does not improve with time. If the fault is intermittent, write down when it happens before you call.
