There are two types of electronic cards for the different applications and configurations of refrigerators. For the purpose
of identification, refer to the following elements:
ELECTRONIC CARDS CONFIGURATION - SIGNALING
Other automatic defrosting refrigerators can have a signaling and alarm board activated through the auto diagnosis
system ADI, which indicates eventual dysfunctions in the product performance through pilot lights blinking for operating
conditions.
Once the anomaly is found, the system starts compressor C and defrosting D lights blinking to indicate the user the

To stop blinking, the power supply interruption is recommended. When restoring it, the “normal” condition re – starts until
the anomaly is found again.
The operation concept is shown in the following diagram:
