TROUBLESHOOTING GUIDE UNDERSTANDING SOUNDS YOU MAY HEAR Your new refrigerator may make sounds that your old one didn't make. Because the sounds are new to you, you might be concerned about them. Most of the new sounds are normal. Hard surfaces, like the floor, walls and cabinets, can make the sounds seem louder than they actually are. The following describes the kinds of sounds and what may be making them. The defrost timer will click when the automatic defrost cycle begins and ends. The thermostat control (or refrigerator control, depending on the model) will also click when cycling on and off. Rattling noises may come from the flow of refrigerant, the water line, or items stored on top of the refrigerator. Your refrigerator is designed to run more efficiently to keep your food items at the desired temperature. The high efficiency compressor may cause your new refrigerator to run longer than your old one, and you may hear a pulsating or high-pitched sound. You may hear the evaporator fan motor circulating the air through the refrigerator and freezer compartments. As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your refrigerator. Contraction and expansion of the inside walls may cause a popping noise. Water dripping on the defrost heater during a defrost cycle may cause a sizzling sound. You may hear air being forced over the condenser by the condenser fan. You may hear water running into the drain pan during the defrost cycle. REFRIGERATOR DOES NOT OPERATE Check if... The power supply cord is unplugged.
