Fridge water rarely announces itself. A defrost drain ices over for weeks, an ice-maker line weeps behind the unit, a door seal sweats through summer humidity. By the time you notice the puddle, the floor underneath has been soaking it up. Here's the exact sequence our refrigeration techs run on every leak call — and the checks you can safely do yourself.
Start inside, not underneath
Pull the crisper drawers and look at the back wall. Water pooling under the drawers points to a clogged defrost drain — meltwater with nowhere to go. A dry interior with a puddle at the front usually means the ice-maker line or inlet valve behind the fridge. Knowing which side the water starts on decides the whole repair.
The five-minute homeowner checks
- Defrost drain: find the small drain hole at the back of the fridge interior. If it's iced over, a gentle flush of warm (never boiling) water often clears it.
- Door seals: close the door on a dollar bill. If it slides out easily anywhere, warm air is entering and condensing — clean the seal first, replace it if it's torn.
- Ice maker: pull the fridge out and check the thin supply line for kinks, cracks or green corrosion at the connections.
- Level: a fridge leaning forward lets defrost water overshoot the drain pan. It should tilt slightly back — check with a phone level app.
When to stop and call us
Stop the moment you find water inside the wall behind the fridge, a warm fridge section with a running compressor, oily residue near the compressor (sealed-system leak), or a leak that returns days after clearing the drain. Those need gauges, OEM valves and sealed-system work — and every day of waiting risks the compressor. Our emergency visits average 90 minutes, and the diagnosis fee is waived with repair.
