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.
