Full guide
What to check before you call
Safe observations first. Stop if anything involves smoke, gas, water near electricity, or a panel you would need to remove.

A wine climate cabinet that is not cooling can have a simple cause: a temperature set warmer than you intended, a door that is not closing fully, or interior vents blocked by bottles. Check the setting, the door and the vents, and protect what is stored. If the interior stays warm after that, stop and book a diagnosis.
A wine climate cabinet that is not cooling as expected can be frustrating, especially when it interrupts a normal household routine. A symptom alone does not identify a failed part, so start with observations that are safe, repeatable, and useful if you later arrange an ASKO service visit.
This guide separates routine care from work that requires testing or disassembly. Do not bypass a lock, safety switch, or error message to keep an appliance running. Taking a few notes now can make the eventual diagnosis faster and more accurate.
Start with the simple conditions
Confirm that the controls have not been set warmer, the doors close fully, and food is not blocking interior air vents. Make the check with the appliance in its normal position and without forcing panels, fittings, or controls. If the result changes after a simple adjustment, run one normal cycle or operation before drawing a conclusion.
If the freezer is cold while the fresh-food section is warm, note that detail because it often points to an airflow or defrost issue. Look for a pattern: whether the issue happens every time, only with a particular load or setting, or after the appliance has been running for a while. That distinction is more valuable than repeatedly restarting the appliance.
| Symptom | Likely cause | Safe check |
|---|---|---|
| Warm refrigerator | Blocked airflow | Clear interior vents |
| Both sections warm | Power or system issue | Check outlet and controls |
| Frost buildup | Airflow restriction | Check door closure |
A wine cabinet is not a refrigerator
A wine cabinet is designed to hold a range suited to wine rather than food-safe cold. The sheet for one ASKO undercounter wine cabinet gives a range of +5 to +20 C, a humidity level of 50 to 80 percent and fan-assisted cooling with Multi Airflow. So the interior can be warmer than a refrigerator and still be working as intended. Check the setpoint and the range in your manual before deciding something is wrong.
Similar complaints compared
| What you notice | What it can point to | What it does not prove |
|---|---|---|
| Cool, but warmer than a refrigerator | A normal range for wine | It does not show a fault |
| Reading drifts after a power cut | Settings or restart state | Check whether your model saves settings on power failure |
| Warm after loading many bottles | Load and airflow | It does not show a cooling failure |
| Warm with the door closed and little inside | A possible cooling fault | This needs diagnosis |
Safe checks that protect the appliance
Consult the use-and-care manual for model-specific controls, filter access, and maintenance intervals. Clean only parts described as user-serviceable, use the recommended cleaning products, and refit every removable part exactly as it was designed to sit.
Before trying another cycle, clear obstructions, reduce an unusually heavy load, and make sure airflow, water supply, or door clearance is not being restricted. Avoid repeated resets: they can hide an intermittent fault and may leave water, heat, or pressure where it should not be.
- Record any displayed message or error code before clearing it.
- Check visible hoses, vents, seals, and plugs without moving electrical connections.
- Use one controlled test rather than several back-to-back attempts.
Safe to try
- Check settings and door seals
- Keep vents clear
- Protect perishable food
Leave to a technician
- Open sealed refrigerant lines
- Test compressor wiring
- Disassemble fans or controls
Settings, notices and what they mean
The sheet for one ASKO wine cabinet lists a sound alarm for an open door, settings saved on power failure, and notices for a filter change and for humidity that is too high or too low. The sheet for another model mentions a SuperCool rapid cooling function and a door lock. A cabinet that was bumped or had its door held open may keep its setting but still need time to recover its temperature.
Why the exact model matters
Features differ between models. A notice that one cabinet displays may not exist on another, which is why the manual for your own model decides which messages are meaningful.
What each result does and does not prove
If the temperature recovers after the setting and door are corrected, the cause was simple. If it does not recover with the door closed and the vents clear, the cause is beyond what you can safely test, and the stored bottles should be moved somewhere suitable.
Know when the symptom needs diagnosis
If the basic checks do not change the symptom, stop at the user-serviceable boundary. Internal wiring, heating circuits, pumps, motors, refrigerant lines, gas connections, and control boards need the correct test equipment and a technician who can verify the repair safely.
Arrange service promptly when performance is getting worse, the appliance trips a breaker, leaks near electrical parts, smells hot or burnt, makes a new grinding noise, or cannot complete a normal cycle. Do not continue operating an appliance that gives a safety warning.
What to tell the technician
Share the model number, the exact symptom, when it began, what settings were selected, and the results of the safe checks above. A photo of a code or a short description of the sound can also help, but never remove a cover to obtain it.
Careful observation is not a substitute for repair, but it is the best first step. Address the simple conditions, preserve any useful error information, and leave electrical, gas, sealed-system, and internal mechanical work to a qualified ASKO technician.
Common questions
Is a warm wine cabinet an emergency?
It is not an electrical emergency, but stored wine is sensitive to warmth, so decide whether to move the bottles while the cause is found.
Could the humidity notice be causing the temperature issue?
Not necessarily. A humidity notice and a temperature drift are different conditions, so treat them separately.
Does unplugging and restarting help?
One restart at the outlet or breaker is a fair test. If the same condition returns afterward, a physical cause is likely.

Official manuals and support notes are available on ASKO Support.
Write down the full model number before ordering parts. Board and sensor revisions can change which part number is correct.
A single power reset can clear a temporary fault, but repeated returns of the same code usually mean a physical cause remains.
Keep vents and filters clear between visits. Restricted airflow often mimics electrical or sensor failures.
If water, burning smells, or sparking are present, stop using the appliance and arrange a professional inspection.
