Minimize Condensation on Refrigerator Door Glass (Models Produced with Glass Doors Only)
On models produced with glass doors, the refrigerator door is equipped with a 5 watt braided wire heater around the
glass perimeter to help minimize condensation formation on the glass.
• The heater in a 601RG door is on 100%.
• The heater in 611G-2 and 650G-2 doors is tied into the condenser fan circuit (see Control Condenser Fan
Operation on preceding page and Figure 3-14 below).
To help minimize condensation on the glass further, the microprocessor detects when the refrigerator door is
opened, via the light switch, then when the door closes, the evaporator fan is energized for 5 minutes. This draws
any warmer moist air away from the door glass. (See Figure 3-14)
NOTE: The evaporator fan in these models also cycles with the compressor.
