Introduction
This new Arctica refrigerator is similar to previous Arctica models with the following exceptions:
• Compressor type
• Compressor control
• 3-speed condenser fan
• 3-speed fresh food fan
The new inverter compressor has 3 speeds and is not controlled from the 120 VAC side of the main
control board. The compressor is controlled by an inverter that receives input from the low voltage DC
side of the main control board. The main control board still makes compressor decisions based on the
input of 4 thermistors, door-open time, and input from the temperature control panel.
The other significant difference from previous models is that the main control board now operates the
condenser fan and fresh food fan at three different speeds. Both fans are actually the same fans found
on previous models.
The new Arctica with inverter compressor is also more efficient than previous models. The increased
efficiency provided by the inverter compressor allows this refrigerator to receive an Energy Star rating.
The Energy Star rating means the refrigerator consumes 10% less energy than the Department of
Energy standard for the specific cabinet size.
This refrigerator is also 5 to 7 decibels quieter than previous models.
This technical service guide covers the new features of this new Arctica refrigerator. For information on
