The short answer
Start with frost forming where a cellar should hold a steady band: on a Cellara by Element wine cellar it accounts for more of these than anything else, and a control set for the refrigerator and not for ice is the next thing to rule out. A wine cellar is not a small refrigerator: it holds a narrow band a long way above freezing, it is expected to hold humidity rather than drive it out, and it is built to stay quiet. Work the list in the order it is given and you will either fix it or know what to tell the technician.
What you observe
- Frost packed on the compartment walls — The insulation you did not ask for, sitting on the surface doing the work.
- Trays that go slushy but never solid — The compartment is close to freezing and not past it.
- NEAR MISS - food is freezing where it should not — That is a control fault in the other direction and it needs a different page.
Causes, most likely first on this brand
- A cellar making frost rather than holding its band — The likeliest cause on this brand: a cellar is not meant to reach freezing at all, so frost inside one means the control or the airflow has drifted rather than that the cabinet is working hard.
- A control set for the refrigerator and not for ice — Next most likely: one dial serves the whole cabinet on this design, so a setting that keeps the fresh-food side pleasant is often a setting that will never freeze a tray of water.
- A door that is opened too often or left ajar — Third on the list: freezing water is the most demanding thing this cabinet is asked to do, and it is the first job to fail when warm air keeps arriving.
- A control or cooling-assembly fault — Least likely, and the only one that is not your work: it sits last because the three above it are free to check and this is the one that ends in a service call.
Check in this order, and why
- Note where in the cabinet the frost forms — Frost in a cellar is a control question, and where it forms tells you which.
- Put the control to its coldest setting and wait a day — Free, and on a single-control cabinet it is the likeliest fix.
- Test the seal and count how often the door is opened — Warm air is what the compartment has least defence against.
What an owner can safely check
- Set the control to its coldest position and give it a full day — One dial serves everything on most cabinets in this class, so this is the cheapest thing that can work.
About 10 min
- Test the door seal with a slip of paper at several points — Where it pulls out freely, warm air is arriving continuously.
Tools: a sheet of paperAbout 10 min
- Measure the room where the cabinet stands — The compartment is the first thing to fail when the room is out of range, so measure before you diagnose.
Tools: room thermometerAbout 10 min
- STOP HERE if the next step means a meter or the rear panel — Behind that panel are the evaporator and live terminals, and that is where owner checks end.
Before you open anything
Safety
Unplug the cellar and take the bottles out before moving it - a loaded cabinet is heavy and top-shy. A capacitor can hold a charge after the power is off. Do not scrape frost off an interior surface with anything metal; let it melt with the door open and the cabinet switched off.
When to call a technician
Call once the setting has been checked, the room is in range and the door seals, and frost still forms inside. On a cellar, call sooner rather than later: a cabinet cooling past its band risks what is inside it, and bottles are the expensive part of this appliance.

What this page does not cover
This page covers wine cellars as a class and does not separate thermoelectric from compressor cabinets, which behave differently at the cold end of their range. That belongs on the family page for your unit, linked below where one exists. Deliberately absent: set-point ranges, humidity figures and part identifiers.
