Troubleshooting Guide 44 Troubleshooting Refrigerator /freezer runs for long periods of time. • Is the condenser area clean? • Has a door (or drawer) been left open for an extended period? Be sure that food is not obstructing proper door closing. • Has a large amount of food been added recently? • On hot days and in warm room temperatures, the compressor runs longer. • There may be normal operation noises related to refrigerant circulation, fan operation, ice maker operation, defrost cycle or compressor operation. Refrigerator /freezer is frosted up. • Has a door (or drawer) been left open for an extended period? Be sure that food is not obstructing proper door closing. • Are doors (and drawer) closing and sealing properly? Contact your authorized Sub-Zero dealer if doors are not adjusted properly. When opening the freezer drawer of over-and-under models, you may notice a side-to-side motion in the drawer. This motion is normal, with the tolerance built into the drawer slides. When the drawer is closed, it will automatically adjust and close with the correct alignment. Outside of the freezer section heats up. • Clean the condenser area. You hear unusual noises. • These noises may be normal operating sounds related to refrigerant circulation, fan operation, ice maker operation, defrost cycle or compressor operation. Noises may be more noticeable when doors are open. You hear occasional buzzing. • Is the water supply connected to ice maker and turned on? Condensation forms inside the unit. • This is normal during periods of higher humidity (summer) and with frequent door openings. • Are doors (and drawer) closing and sealing properly? Light bulb needs to be replaced. • Refer to lighting information on page 26. Shut off power to the unit at the circuit breaker before replacing light bulbs. Wear protective gloves when handling bulbs.
