Built-In Use & Care 25 subzero.com Operations DOOR AND DRAWER CLOSING Over-and-under models: The refrigerator door has a door closing cam to help in closing the door. With the door opened to about 110°, the cam will hold in the open position if the door is stopped. As you close the door, the cam will take over at about 15° to help close the door. The freezer drawer has a self-closing mechanism. The incline, built into roller assemblies on the drawer, uses gravity to assist in closing the drawer. If the built-in unit is positioned in a corner, you may want to install an optional door stop, which limits door opening to 0°. This door stop is provided with each built-in model and is shipped in a plastic bag in the grille area. All refrigerator, all freezer and side-by-side models: The refrigerator and freezer doors have spring-loaded closure mechanisms. As the doors are closed, the door closure engages to help close and seal the doors. A 0° door stop is provided with each unit and is shipped in a plastic bag in the grille area. Sounds You may hear some noises in the normal operation of the built-in unit. Surrounding acoustics like walls, floors and cabinets may affect the sound of your unit. For example, a gurgling or running water sound is probably refrigerant circulating through the tubing. For external dispenser models, the ice dispenser motor inside the refrigerator door closes five seconds after either the ICE or WATER key pad is released. During the ice maker cycle you may hear the sound of ice dropping into the container or the water valve operating while refilling the ice maker with water. During the freezer defrost you may hear crackling or sizzling as the heat from the defrost element clears the frost from the freezer coil and water runs into the water pan. While the compressors are in operation, you may hear a slight hum. During the start-up and shutdown of the compressor, you may feel vibration for a few seconds. Some of these noises may be enhanced when the doors of the unit are open. CONDENSER FAN MOTOR All built-in models have a fan behind the grille to cool the compressor area. This fan runs with either compressor. AUTOMATIC DEFROST Sub-Zero built-in models are equipped with an automatic defrost system. The refrigerator section will defrost during each off cycle of the refrigerator compressor. The freezer section is controlled by an energy-saving adaptive defrost system, which defrosts as needed.
