5.4.2. Temperature Alarm

If the Electronic control detects a high internal temperature (above –12° C), at the freezer compartment, it will

activate the Alarm Icon and the Freezer Temperature Icon "–12° C" will blink.

Note: To prevent "wrong" alarm, this alarm status is disabled on the following circumstances:

During the first 6 hours after the product is connected to the energy;

During defrost process;

During the first 2 hours after a defrost;

During the first 2 hours that one of the doors was open.

If the product takes over the temperature reaching –16° C, the Alarm will be automatically disabled and the

product will return to the normal operation.

When constant, there is the chance of a real technical failure, check its source, which could be related to: ice

blockage, leakage of refrigerant fluid, compressor's low compression, etc.

5.4.3. Open door

When any of the doors (freezer or refrigerator) remains open more than 2 minutes, the electronic control system

will emit a sound Alarm "BIP", the open door icon (corresponding to the compartment) will blink and the alarm

icon will switch on, indicating that it's open.

To turn off the sound sign just close the door or press the turn off alarm (OK) key, in this second situation, the

open door icon will keep blinking until the door is closed.

After 6 minutes, if the door has not been closed yet, the electronic control will assume a safety routine, turning

off the refrigerator lamps, putting in action the fan motors (freezer & refrigerator) and the

Compressor, even whether the doors are open, as it's working in normal cycle, trying to keep food refrigerated.

When constant, check if the magnet on the doors (freezer and refrigerator) end cap exists, poor contact

between terminals/connectors (LCD Display), interrupted wire between LCD display x electronic control and

then the interface board.

COMMENTS: When the open door alarm is disabled by the key turn off alarm (OK) but if the door is kept open,

it will be again activated after 2 minutes. This will repeat in every 2 minutes until the door is closed.
