The short answer
Water in or under a Cordova refrigerator is almost always condensation and defrost meltwater that has lost its drain path, because a cabinet of this class usually has no water supply at all. Find out whether the water is inside the cabinet, in the vent cavity or on the floor, and the cause follows immediately.
What you are actually seeing
- Water pooling in the bottom of the fresh food compartment — Means: on-page
- A wet floor in front of or beside the cabinet — Means: on-page
- Water inside the exterior vent cavity — Means: on-page
- Water appearing only in humid weather or after a hot day — Means: on-page
- The drip tray behind the cabinet overflowing — Means: on-page
- Contents warming along with the water — Means: different-fault — Go to: cordova-refrigerator-cooling-failure
- Frost concentrated at one edge of the door — Means: different-fault — Go to: cordova-refrigerator-door-seal
- Body: Match what you see before you change anything. Water pooling in the bottom of the fresh food compartment. A wet floor in front of or beside the cabinet. Water inside the exterior vent cavity. Water appearing only in humid weather or after a hot day. The drip tray behind the cabinet overflowing. Some near-miss symptoms belong on a different page: Contents warming along with the water points at a cooling loss rather than a drain problem, covered on cordova-refrigerator-cooling-failure; Frost concentrated at one edge of the door points at a sealing fault letting humid air in, covered on cordova-refrigerator-door-seal.
Causes, ranked for this machine
- A blocked interior drain hole letting defrost water pool inside the cabinet — Why this rank: First because it is the one drain on the cabinet and it blocks with food debris and mould in a way owners never think to check
- A drip tray or drain tube that has been dislodged by travel — Why this rank: Everything behind this cabinet is shaken for hours at a time, which no household refrigerator experiences
- A door seal fault letting humid air in, which condenses and then runs — Why this rank: This links the water to the door and explains water that comes and goes with the weather
- Rain entering the exterior vent cavity and running inside — Why this rank: A vent open to the outside in a moving vehicle collects driving rain, and a missing or damaged cover makes it worse
- A cracked liner or a failed drain fitting — Why this rank: Last because it is rare and is the only cause that needs a repair
- Body: Ranked for a recreational-vehicle and marine refrigerator, which may be an absorption cabinet running on gas or electricity or a compressor cabinet running on twelve volts, and which is fitted into a vented cavity in a moving vehicle. Most likely: A blocked interior drain hole letting defrost water pool inside the cabinet. First because it is the one drain on the cabinet and it blocks with food debris and mould in a way owners never think to check. Next most likely: A drip tray or drain tube that has been dislodged by travel. Everything behind this cabinet is shaken for hours at a time, which no household refrigerator experiences. Third: A door seal fault letting humid air in, which condenses and then runs. This links the water to the door and explains water that comes and goes with the weather. Fourth: Rain entering the exterior vent cavity and running inside. A vent open to the outside in a moving vehicle collects driving rain, and a missing or damaged cover makes it worse. Fifth: A cracked liner or a failed drain fitting. Last because it is rare and is the only cause that needs a repair.
What to check, in order
- Decide first whether the water is inside the cabinet, in the vent cavity or on the floor
- Find the interior drain hole and check it is clear
- Check the drip tray and the drain tube behind the cabinet through the exterior vent
- Test the door seal with a paper strip at several points
- Body: Each check rules out the causes above it. First, decide first whether the water is inside the cabinet, in the vent cavity or on the floor. Second, find the interior drain hole and check it is clear. Third, check the drip tray and the drain tube behind the cabinet through the exterior vent. Fourth, test the door seal with a paper strip at several points.
Checks you can safely make yourself
- Dry the interior completely, close the door and check after several hours whether water reappears inside or outside the cabinet — Tools: cloth — Time estimate: several hours
- Find the small drain hole at the back of the fresh food compartment and clear it gently with warm water — Tools: warm water, soft brush — Time estimate: a quarter of an hour
- Isolate the cabinet, open the exterior vent and check that the drip tray is seated and the drain tube is in place and not kinked — Tools: screwdriver, torch — Time estimate: half an hour
- Close the door onto a paper strip at four points and check each one drags — Tools: paper strip — Time estimate: a few minutes
- Check the exterior vent cover is present, undamaged and correctly fitted, so driving rain cannot enter the cavity — Tools: screwdriver — Time estimate: a quarter of an hour
- Body: Checks an owner can make with the cabinet isolated or simply observed. Step one: Dry the interior completely, close the door and check after several hours whether water reappears inside or outside the cabinet. Tools: cloth. Time: several hours. Step two: Find the small drain hole at the back of the fresh food compartment and clear it gently with warm water. Tools: warm water, soft brush. Time: a quarter of an hour. Step three: Isolate the cabinet, open the exterior vent and check that the drip tray is seated and the drain tube is in place and not kinked. Tools: screwdriver, torch. Time: half an hour. Step four: Close the door onto a paper strip at four points and check each one drags. Tools: paper strip. Time: a few minutes. Step five: Check the exterior vent cover is present, undamaged and correctly fitted, so driving rain cannot enter the cavity. Tools: screwdriver. Time: a quarter of an hour.
Safety first
Safety
Isolate the cabinet at its breaker and close the propane supply before opening the vent cavity, and dry the floor before working near the cabinet. Do not pour water into the cavity to test a drain. A refrigerator holds food safely at 40 °F (4 °C) or below. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. fridge-40f unplug-before-service
Where the owner fix ends
Call a technician when the interior drain is clear, the drip tray and tube are correct, the seal passes the paper test and the vent cover is sound, and water still appears. A cracked liner or a failed drain fitting means opening up a cabinet that is built into a wall, and that is not owner work.

Generalized information
This page is generalized across the Cordova refrigerator line. Absorption cabinets and twelve-volt compressor cabinets share the ranking above but almost none of their parts, and this page does not cover a specific model, a specific cooling unit or a particular coach builder's vent installation.
