7-4-1. The dispenser heater is always on.
7-4-2. The DV heater is always on and located Between refrigerator doors.
7-4-3. The I/CASE heater cycles which is located inside the icemaker helps to remove residual ice from the ice case.
The heater turns on when the temperature reaches 21.2°F(-6°C) on and turns off when the temperature reaches 28.4°F(-2°C)
