Direct answer: If your LG refrigerator has water under the crisper drawer, the most common cause is a partially frozen or clogged refrigerator defrost drain that lets meltwater run into the fresh-food section instead of down to the drain pan.
Most likely: Start by pulling the drawers and shelf above them, drying the area, and looking for a thin sheet of ice, water tracks from the back wall, or slush near the rear drain area. Those clues point to a drain problem long before they point to a bad part.
When this leak shows up, it usually repeats in the same spot: under the deli pan or crisper drawers, then it creeps forward onto the shelf or floor. Reality check: a little puddle under the drawers often started as ice you never saw. Common wrong move: chipping at interior ice with a knife and cracking the liner.
Don’t start with: Do not start by ordering a refrigerator control board or tearing into the sealed cooling system. This problem is usually blockage, ice, or door-seal related.
The shelf above looks mostly dry, but the bottom of the fresh-food compartment keeps collecting water under the bins.
Start here: Start with the rear floor of the refrigerator compartment and look for a blocked or frozen drain path.
You find a thin slab of ice under the bins that later melts into a puddle.
Start here: Treat this like a defrost drain problem first, not a water supply leak.
You can see droplets or a wet trail coming down the rear interior panel into the drawer area.
Start here: Check for frost or ice at the back wall and confirm the drain opening is not iced over.
The puddle shows up after heavy use, warm groceries, or when drawers and bins are overstuffed.
Start here: Check door sealing, drawer alignment, and anything keeping the refrigerator door from closing flat.
This is the most common reason water ends up under the crisper drawers. Defrost water cannot reach the drain pan, so it spills into the fresh-food section and refreezes or puddles.
Quick check: Remove the drawers and look for ice or standing water near the back center of the refrigerator floor.
Warm moist air gets in, frost builds where it should not, and the next defrost cycle sends extra water into the compartment.
Quick check: Look for frost on the rear panel, food packages touching the back wall, or a door gasket that is twisted, dirty, or not sealing at the corners.
A leaking gasket can create repeated condensation and frost, especially around the fresh-food section, which later melts and runs to the bottom.
Quick check: Close the door on a strip of paper at several spots. If it slides out easily in one area, inspect that section of gasket and door alignment.
Less common, but if the drain opening is clear and water still bypasses it, the meltwater guide may be damaged or out of place.
Quick check: After clearing visible ice, pour a small amount of warm water toward the drain area and watch whether it enters the drain or escapes into the liner floor.
You need to separate a simple interior drain issue from a door-seal problem or a leak coming from somewhere else.
Next move: If you find ice or a wet trail starting at the back wall or rear floor, stay on the drain-and-frost path in the next step. If the area is dry inside but water shows up on the kitchen floor, the leak may be from the external water line, drain pan area, or another source outside this symptom pattern.
What to conclude: Most inside-the-fridge puddles under the crispers start with defrost water that failed to drain, not with a bad water valve.
A frozen drain opening is the most common fixable cause, and it can often be confirmed without taking the refrigerator apart.
Next move: If warm water begins draining normally and no more water pools under the drawers over the next day or two, the drain was the problem. If water still backs up or immediately spreads across the refrigerator floor, the drain is still blocked deeper down or the water channel is not guiding water into the drain correctly.
What to conclude: A drain that clears and stays clear points to a simple ice or debris blockage. A drain that will not take water points to a deeper clog or a damaged drain path.
Clearing the puddle helps, but if warm air keeps getting in or airflow is blocked, the ice and water usually come back.
Next move: If the gasket seals evenly and the refrigerator stops building frost or water under the drawers, you likely solved the repeat cause. If frost keeps returning on the back wall or the gasket will not hold shape, move to the next step and consider a failed gasket or hidden frost issue.
This is where you stop guessing. If the drain now flows but water still misses it, the likely parts are limited and specific.
Next move: If water now goes straight down the drain and the compartment stays dry, put the refrigerator back in service and keep an eye on it for a few days. If the drain path is visibly damaged or the gasket clearly will not seal, that is the point where a replacement part makes sense.
Once the symptom is narrowed down, the right next move is usually straightforward.
A good result: A dry drawer area, no new ice sheet, and no back-wall dripping over the next couple of days confirm the repair path was right.
If not: If the puddle comes back even though the drain opening is clear and the gasket looks good, the problem is likely deeper in the defrost drain path or behind the rear panel.
What to conclude: You either solved a common drain-and-moisture problem or you have enough evidence now to avoid wasting money on the wrong part.

That spot is the low point in many fresh-food sections. When defrost water cannot get down the refrigerator drain, it runs to the bottom and collects under the drawers first.
Not usually. If the water is under the crispers inside the refrigerator, a clogged or frozen refrigerator defrost drain is more common than a supply line leak. A supply line leak more often shows up near the back of the unit or on the floor.
Use warm water, not boiling water. Small controlled amounts are safer for the interior liner and easier to manage. If the drain still backs up, do not force it with sharp tools.
Only if you confirmed the gasket is not sealing. A bad gasket can cause extra frost and repeat drain freeze-ups, but it is not the first thing to replace unless the seal problem is obvious.
Then look closely at the visible refrigerator drain trough or water guide. If that piece is cracked, warped, or out of place, meltwater can bypass the drain and end up under the crisper drawers.
