Operating principle

Inspection method

The relay momentarily energizes the start winding to start the rotation of the compressor motor.

Most later refrigerator models use a solid state type relay.

Unlike the mechanical type relay, the solid state relay has no coil and no moving contacts.

This relay consists of a small solid state wafer that has a low resistance at room temperature.

The wafer is positioned between electrical terminals that connect to the compressor terminals.

As voltage is initially applied to the compressor circuit, current flows through the run winding and, in parallel, through the relay and start winding . Initially , the resistance of the relay is low enough to pass sufficient current through the start winding and permit the compressor to start.

Then, instantaneously, the resistance of the relay goes high-in effect, reducing the current flow through the relay to a trickle . This trickle current causes the resistance of the relay to remain high , thus keeping the relay "open".

This type of relay is called a PTC(positive temperature coefficient) relay because the resistance goes high as the temperature increases.

The solid state relay can be tested for continuity, using an ohmmeter. The measured resistance of the relay, at room temperature, should be within 10% of the value stated on the schematic wiring diagram for the particular model.

RL28DBSI1/BWT, RL23DATS1/XEK, RL28DATW1/XEK, RL25DATW1/XEK, RL28DBSI1/XEK specifications

Samsung’s refrigerator models RL23DATW1/XEK, RL28DBSW1/BWT, RL25DATS1/XEK, RL28DATS1/XEK, and RL28DBSW1/XEK represent the brand's commitment to combining innovation with functionality. These refrigerators are designed to meet the modern consumer's needs while providing high durability and efficiency.

One of the primary features of these models is the all-around cooling system. This technology ensures that every corner of the refrigerator maintains a consistent and optimal temperature, which is crucial for preserving food freshness and nutritional value. The cooling system prevents the formation of ice buildup and eliminates the hassle of defrosting.

Energy efficiency is another key characteristic across these Samsung models, with many boasting a high energy rating. This not only helps to reduce the overall energy consumption and utility bills but also minimizes environmental impact. The Eco Mode is a standout feature that allows users to optimize energy use without compromising storage performance.

Additionally, the digital inverter technology plays a vital role in maintaining the refrigerator's temperature. This feature adjusts the compressor speed according to the cooling demand, resulting in less noise and greater energy savings compared to traditional compressors.

The spacious interior design of these refrigerators accommodates large grocery loads, with adjustable shelves providing flexibility for organizing various items. The ample freezer space also allows for efficient organization of frozen goods, making meal prep easier.

Samsung's innovative Twin Cooling Plus technology enhances flavor preservation. By using separate cooling systems for the fridge and freezer compartments, it prevents odors from mixing, which ensures that fruits and vegetables stay fresh for longer times.

Furthermore, these models feature a sleek and modern aesthetic that complements any kitchen decor, making them both functional appliances and stylish furnishings. The easy-to-use controls and LED lighting simplify operation while providing clear visibility of stored items.

In summary, Samsung refrigerators RL23DATW1/XEK, RL28DBSW1/BWT, RL25DATS1/XEK, RL28DATS1/XEK, and RL28DBSW1/XEK offer a blend of advanced technologies and thoughtful design features. With all-around cooling, energy efficiency, and a spacious layout, they cater to the needs of contemporary households, ensuring that food remains fresh, organized, and easily accessible.
