TROUBLESHOOTING AND SERVICE GUIDE: The following is intended as a quick service guide designed to diagnose most common problems. It is intended to be used only as a guideline. Should the unit require actual replacement of components those must be done by a trained and licensed refrigeration professional. While the unit is within the factory warranty period, all repairs require prior factory authorization before the work is actually performed.
• EVAPORATOR COIL ICED UP: Is the evaporator coil iced up due to incorrect (too low) of a set point? Verify that the unit defrosts properly and the evaporator coil is clean of heavy frosting during operation. NOISY OPERATION: • DEBRIS IN THE BAN BLADE: Is there debris in the condenser fan blade? Not only can debris physically stop the fan blade from rotating (as discussed previously), but is can also block airflow thus preventing the unit for cooling.
CONTROLLER SETTINGS AND ADJUSTING TEMPERATURES : Your ALFRESCO refrigerator features an exclusive digital programmable thermostat (see figure 1) that controls all functions of the unit. The operating temperature of the unit is user-adjustable from 25°F to 45°F. The refrigeration control has been preset at the factory for normal, everyday operation under standard room conditions.
OPERATIONAL PARAMETERS There are two sets of parameters that can be access on this controller. Some require a password, other do not. 1. Press the “SET ” button for 1 second to display the set point temperature (35°F) default. 2. Hold the “SET ” key for at least 5 seconds once more (the set point starts flashing and after 5 seconds the letters PS will appear on the screen). PS = PASSWORD 3. Release the “SET ” key. 4.

UNDERSTANDING THE REFRIGERATION CYCLE: The Refrigeration Controller unit that manages all the refrigerator operations and performance is a rugged and highly sophisticated commercial grade Sporlan Electronic Controller. Like all refrigerators, as the unit cools and maintains the desired product temperature, it’s internal temperature will fluctuate between ON and OFF periods depending upon ambient temperature, how many times the door is open and for how long it’s held open.
