The short answer
Water under a refrigerator comes from one of three places: the defrost drain, the water supply or condensation that should never have formed. On a Frigidaire refrigerator the order below reflects that this is one chassis sold under several nameplates, usually a compact unit, and often living in a garage, a basement or a utility room. Where you find the water tells you almost everything, so look before you move the cabinet.
What you actually observe
- Water pooling inside, under the crisper drawers — That is the defrost drain backing up rather than a supply leak, and it is the commonest version of this fault.
- The nameplate on the door does not match the parts list you found — One chassis is sold under several names, so the badge is a poor guide to what is actually inside it.
- NEAR MISS: water on the door front or beading on the outside — That is room humidity condensing on cold steel, not a leak, and it belongs on a different page.
The causes, most likely first on this brand
- Ice built up in the compartment, melting all at once — When a stalled defrost finally runs, weeks of accumulated frost leaves at once and overwhelms a drain built for a normal cycle. Ranked first on a Frigidaire refrigerator: the badge on the door tells you very little about which defrost arrangement is behind it, so confirming whether this unit defrosts itself at all is the first move rather than the third.
- A door that is not sealing and is letting humid room air in — Warm air condenses on cold surfaces, and enough of it runs to the floor as water that looks exactly like a leak. Ranked second on a Frigidaire refrigerator: the gasket on a chassis at this price is thin, and a single sagging door is enough to keep it from sealing.
- A cabinet tilted so the drain pan spills or the drain runs the wrong way — The pan under the cabinet holds the water it is given only if it sits flat, and the drain relies on the same thing. Ranked third on a Frigidaire refrigerator: these units are light and are moved often, and a unit that is off level runs noisy and drains badly at the same time.
Check in this order, and why this order
- Establish whether this cabinet defrosts itself at all, and when it last did — Whether and when this cabinet last completed a defrost decides everything that follows, so settle it before opening anything.
- Look at where the water actually is before moving anything — Inside under the drawers, under the freezer floor and out on the boards are three different faults.
What an owner can safely check
- Switch off and leave both doors open for a full defrost before judging anything — Leave it standing several hours. Half the faults on this cabinet disappear here.
Tools: towelsAbout 25 min
- Find the drain hole at the back of the fresh food compartment and flush it through — Warm water from a turkey baster clears most blockages. Do not push anything rigid into the tube.

- STOP HERE if the next step needs a meter on live terminals or a sealed panel off — That is the line where an owner check ends and a service call begins.
Before you open anything
Safety
Water and electricity share the floor behind a refrigerator, so switch the unit off at the breaker before mopping under it or pulling it out. Unplug it before removing any panel, since a capacitor can hold a charge after the power is off. The cabinet is heavy and will run away on its rollers, so get help and shut the water supply off first.
When to call a technician
Call once the drain is clear, the fittings are dry and the seal is closing and water still appears, because what is left is inside the cabinet and needs a panel off. Call at once if the water is reaching an outlet or a cable, if it is running under kitchen units, or if a fitting is weeping faster than you can dry it, and shut the supply off while you wait.

What this page does not cover
This page covers the Frigidaire / RCA / Thomson refrigerator as a class rather than one family or model line. Drain routing, pan shapes, filter head fitments and supply connections differ from build to build and are deliberately not here. Where a family or model page exists for your cabinet, that page is the more specific answer and the one to read first.
