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.

REFRIGERATOR DOES NOT OPERATE

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.

LFC20740, LFC22740 specifications

LG Electronics has long been a leader in innovative home appliances, and its refrigerator offerings, particularly the LFC22740 and LFC20740 models, showcase their commitment to quality, functionality, and modern technology. These two refrigerator models are designed to meet the needs of contemporary households while adhering to the highest standards of energy efficiency and performance.

The LG LFC22740 is a 22 cubic feet, French door refrigerator that provides ample storage space without overwhelming a kitchen. One of its standout features is the Smart Cooling System, which employs advanced cooling technology to maintain optimal humidity and temperature levels. This system ensures that food stays fresh longer, thereby minimizing spoilage. The Linear Compressor, which is central to the Smart Cooling System, operates with fewer moving parts, leading to improved energy efficiency and reduced noise levels.

On the other hand, the LG LFC20740 offers similar quality but in a slightly smaller 20 cubic feet capacity. This model also utilizes the Smart Cooling System, ensuring that your groceries are kept at the perfect temperature, whether it’s a hot summer day or a chilly winter night. Both models feature a multi-air flow system that allows cold air to circulate throughout the refrigerator, maintaining consistent temperatures in every corner of the unit.

In terms of storage options, both LFC22740 and LFC20740 come equipped with adjustable shelving. This flexibility allows users to customize their storage space according to their needs, whether it’s for large party platters or day-to-day items. Additionally, the refrigerator compartments include humidity-controlled crispers, which are ideal for storing fruits and vegetables, ensuring they stay fresh and crisp longer.

For added convenience, both models feature an external ice and water dispenser. This not only provides instant access to chilled water and ice but also adds a touch of sophistication to the overall design. The sleek finish of these models, available in stainless steel, makes them an attractive addition to any kitchen décor.

In summary, the LG LFC22740 and LFC20740 are not only aesthetically pleasing but also functional and efficient. With their advanced cooling technologies, customizable storage options, and user-friendly features, these refrigerators are an excellent investment for those looking to upgrade their kitchen appliances.
