Why are the inside walls wet?
The short answer
The walls are wet because damp air is getting in and cooling down, so what it was carrying lands on the liner. Sub-Zero Appliance Repair Denver works back from the seal and the door habit to the cause — (303) 729-0972.

Before you call
- Count the door openings on a busy evening. A cabinet opened every few minutes never gets the chance to dry its own walls.
- Cover what is going in. Sub-Zero names wet produce and moisture-producing food as a cause of excess damp inside.
- Take out the load that is stacked against the vents; the manufacturer puts blocked airflow on the same list.
- Shut the door on a strip of card at several points round the frame; anywhere it pulls out without drag, the seal is loose.
Stop here and call Sub-Zero Appliance Repair Denver on (303) 729-0972 if the walls are still running with the seal good and the load thinned out.
What it usually turns out to be
-
Room air, let in often
Damp shows on the walls nearest the door and fades towards the back, and it is worst on the evenings the kitchen is busiest.
Quoted after the diagnosis
-
A seal no longer closing
Air feeds in continuously rather than in bursts, so the wall stays wet all day and the drain has to keep pace with it.

-
Air that cannot circulate
Shelves packed solid stop the flow from the vents, and a pocket of still air behind the load is where the moisture settles.

-
Damp arriving with the house
A kitchen cooled by an evaporative system carries more moisture than the weather outside suggests, and every opening brings some of it in.

When it is worth a visit
Wet walls with a sound seal, a sensible load and the door mostly shut are the cabinet's own problem rather than the kitchen's, and the next things to look at sit behind panels. A technician reads the compartment temperatures, the air path and the drain in one visit.
Which wall is wet tells you a lot
Damp spread evenly over both side walls, worst on a hot evening, is the room getting in through the door: it arrives with the air, it settles wherever the liner is coldest, and it dries back when the kitchen quietens. Damp concentrated along one edge, in the same band every day, is air finding a way past the seal at that point, and it will not dry back because the supply of it never stops.
The one to act on quickly is damp that has started collecting rather than clinging. Once water gathers on a wall it runs, and everything it runs to — the drawer tops, the trough at the back, the floor of the compartment — is a drain problem waiting behind a moisture problem.
Follow-up questions
Is there a humidity control I should be adjusting?
Probably not. Sub-Zero states there is no humidity control on its storage drawers other than on models 542 and 561, so on almost every cabinet the damp is governed by what goes in, how often the door opens and whether the seal is holding.
Denver air is dry — why is anything condensing at all?
Because the air the cabinet sees is kitchen air, not outdoor air. Cooking, washing up and an evaporative cooler all put moisture into a room, and every opening swaps a little of the cold dry air inside for a lot of the room's.
Do wet walls damage anything if I leave them?
They feed the drain, and a drain that cannot keep pace sends water under the drawers and out to the floor. Treating a wet liner as an early warning costs less than meeting it later as a puddle — Sub-Zero Appliance Repair Denver, (303) 729-0972.
