This is normal: small differences in temperature are necessary for the unit to work properly. When the cellar initiates a defrost cycle, the temperature rises slightly. When the cooling system's cycle starts, the temperature cools down. 

Such changes happen over a short period of time and their influence is too minimal to impact wine preservation. Liquid tends to keep an average temperature by physical law. For example, if a swimming pool's temperature is 80 degrees and, one night, the outdoor's temperature drops to 65 dergrees, the water temperature will not drop as much and should be around 77 degrees. 

Ajust the front glide feet until the door is levelled with the cellar. Verity the door seals. The room may require a colder setting. Try not to open the door too often.

Make sure that the drain coming from inside the unit to the evaporation pan is properly located and in place. If so, during hot and humid days, you might have to remove the excess water with a sponge.

Check whether the seal on the door is tight (closes well). Faulty seals can result in heat entering the wine cellar and causing ice to form. If the seal is tight , there may be a problem with the cooling device.

Find where the noise is coming from. A crackling sound might be caused by the cooling fluid, which is normal. At the end of each cycle, you might hear a bubbly noise coming from the fluid circulating in the pipes., normal again. The interior walls contracting and expanding may also cause cliclking sounds or cracking sounds. If the noise seems to be coming from elsewhere, adjust the front glide feet until the unit is levelled. 

Make sure that the door is closed properly. Add a separate thermometer inside the cellar to see if the cellar'S thermometer indicates the same temperature. If tehh results are different, recalibrate the unit. Verify this subject in your owner's manual.

During highly humid times, especially during the summer, this can happen.

The thermal windows need to be changed.

Make sure the lock is properly aligned with the L-shaped piece. Make sur ethe door is levelled, and that the top and bottom hooks align with the top and bottom stops. Make sure that shelves are properly installed and that the cellar is levelled.

Make sure the lock is properly aligned with the L-spaed piece. Make sure the door is levelled with the cellar.

Adjust the front glide feet so that the door is levelled with the cellar.

Adjust the front glide feet so that the two doors are properly aligned.
.

Make sure that the doors are aligned with each other and levelled with the cellar. 

Make sure there is power running in your electricity circuit. Also, your wine cellar should be the only device plugged into your wall socket. We recommand dedicating a 15-amp circuit solely for powering the cellar.

Il est possible que la température de la pièce soit plus élevée que la normale, ou que le cellier soit à pleine capacité. Vérifiez que la porte du cellier ferme correctement, que le contrôle de température est bien réglé et que le joint d'étanchéité de la porte est en bon état.

Adjust the front glide feet so that the cellar is levelled.

An E1 or E2 error code means that the temperature sensor of the upper zone is not working properly. An E3 and E4 error code means that the temperature sensor on the lower sone is not working properly. 

In order to circulate air while maintaining the set temperature inside the cellar, the fan must cycle on and off even when the compressor is off. The fan will cycle On and OFF while the compressor is off every 10 seconds: this is called ''semi-speed status''. This cycle is normal and meant both to circulate air and as well as to ensure the continued operational status of the fan. If the fan stops completely and does not complete its cycle, the fan is non-operational.
