Anti-Bacteria Filter; Component Tests; Electronic Control / Self-Test Routine - Whirlpool Multibras ARC8140IX Service Manual

6.15 – Anti-Bacteria Filter:
The Refrigerator is fitted with a "special" Anti-Bacteria Filter located behind of the vegetable Drawer at
the refrigerator air return. This filter acts by absorbing characteristic odors and bacterias of certain food
which circulate inside the product. It thereby prevents these foods from losing their natural flavor and
smell characteristics.
The Anti-Bacteria Filter should be replaced around 6 months of life, therefore the LCD panel will show/
advise this correct time through a special Caution Alarm "AF" on the Display (see item Alarm System).

7.1. Electronic Control / Self-Test Routine

This refrigerator has an Automatic Test Routine (works automatically, without manual operation) that is
always executed when the product is energized to the power supply, in order to verify the functioning of
the main components of the product. This routine operates as follow:
# Turn off the product from the wall socket, wait 10 seconds and turn it on again
Note: At this moment, an inner temperature check will occur in the evaporator, through the Defrost
Sensor, and then the Routine will start automatically.
• The Defrost Heater is energized for 6 seconds
• Freezer Fan Motor is energized for 6 seconds
• Refrigerator Fan Motor is energized for 6 seconds
After 18 seconds, from the result (temperature) gained from the Defrost Sensor, the Electronic Control
will manage the activation of the compressor and fan motors, as follow:
# If the Defrost Sensor is warm (temperature > 0
• Compressor and fans will be energized / turned on
# If the Defrost Sensor is cold (temperature < 0
• Compressor and fans will not be energized / (will keep off).
After 328 seconds (5.5 minutes) the product is energized, an automatic check will occur for all the
Sensors (Refrigerator, Freezer & Defrost)

proceedings will follow as described in item – Alarm System.
# In case of no failure is detected
