How many readings were taken? How? Using what type of device?
Ensure that the value indicated is not the result of an instant reading taken while the compressor was shut down (the internal temperatures then rise again).
3.3 Odours, moulds and labels coming off:
The atmosphere in the cabinet is very humid: has the filter been replaced? (to be replaced annually)
If not, replace the carbon filter.
3.4 Water in the bottom of the cabinet (or on the floor in front of the cabinet)
This is not detrimental to the device and can be generated in the event that ambient temperatures are higher than normal (very high temperatures)
Is the device new?
Readjust the wine cabinet (the feet are adjustable) or tilt it carefully towards the rear and left to force the flow of condensation.
Does the door shut correctly?
Check that the door closes correctly and that the seal is airtight.
Are the internal temperatures correct?
Check the average temperatures in the wine cabinet.
Record the minimum and maximum at a given point in the cabinet or insert a temperature recorder:
If the delta temperature is very close to the set point(4°C or more), at an average of 12°C this should equate to a minimum peak of 8°C and a maximum of 16°C. Adjust the cooling thermostat.

White lines at the bottom of the tank:
These are lines of chalk from the water, which has dried after it has drained away. See below.
3.5 The temperature is too high
The best way to determine a meaningful diagnosis is to fit a temperature recorder for 24 to 48 hours.
The curve clearly illustrates the average temperature and the corresponding fluctuations linked to the shut-down and start-up of the compressor or winter system.
Also place a submersible thermometer in a bottle filled with water to determine the exact temperature of the liquid.

Where is the thermostat positioned? (if the ambient temperature is higher than 14°C)
The required ambient temperature can be a readjusted reading: place the thermostat on a colder application.
Check the functionality of the thermostat: if it is faulty, replace it (only to be completed by specialist technicians)
Is the compressor cooling?
Several minutes after the compressor has been operating, place your hand on the vaporizer inside the cabinet:
If it is cold the refrigeration process is in progress.
If it is not cold, refer to the checks listed below.
Is the compressor continuously in operation?
Yes:
Check that there is no gas leak or an obstruction on the refrigerating circuit.
(Only to be completed by specialist technicians)
Replace the faulty part (condenser, vaporizer, repair the welding) (only to be completed by specialist technicians).
No:
Check the thermostat setting and adjust if necessary.
Check the gas load in the system, if there is not enough; refill (only to be completed by specialist technicians).
L IGHTS AND THE THERMOMETER : (on the following models)
Models with two lights and a thermometer in the centre, CV range ...
Located to the left of the thermometer, this light illuminates ORANGE when the heating circuit is in operation.
Located to the right of the thermometer, this light illuminates GREEN when the compressor is in operation. This is not a light that can be switched on.
The lights switch on and off intermittently when the corresponding (cooling or heating) system is activated. This is perfectly normal.
