If there is a significant difference (more than 4°C) to the set point temperature, replace the display or the control card (only to be completed by specialist technicians). A maximum tolerance of +/- 3°C is permitted.
Check the Ω values of the sensors (only to be completed by specialist technicians)
Temperature is too high (compression and thermoelectric devices):
Check the temperature control: the ambient temperature may require the thermostat to be adjusted.
1. Maybe the door is opened too frequently, preventing the temperature from returning to the required level.
2. The door does not close completely.
3. Joint on the door is not airtight.
Temperature is too high (not standard, approx. 20°C or higher):
The compressor is continuously rotating without cooling:
1. Control card and/or sensor faulty.
2. Refrigerant leak.
3. Obstruction on the refrigerating circuit.
Temperature is too high (thermoelectric wine cabinets)
The ambient temperature may be too high and requires the temperature setting to be adjusted.
The technical limit of this refrigerating system, known as the PELTIER effect or thermoelectric setting generally enables a maximum temperature of 15°C below the ambient temperature to be achieved.
This is why it is advised to operate these devices at an ambient temperature of around
20°C/maximum of 25°C.
2.7 Fluctuations in the displayed temperature values
The device displays the instant air temperature in the cabinet and not the specified temperature
(refer to the device's operating instructions).
Different temperature values can therefore be recorded and do not precisely reflect the required temperature. This is perfectly normal.
