Modern household appliances of the brand Sharp famous for their reliability and advanced cooling technologies, however Correct startup of the device is a critical step. Many users mistakenly believe that it is enough to simply plug the cord into an outlet, but the inverter compressor system requires proper preparation. Incorrect actions in the first minutes of operation can shorten the service life of the unit or lead to incorrect operation of the sensors. Plasmacluster proper preparation is required. Incorrect actions in the first minutes of operation can shorten the service life of the unit or lead to incorrect operation of the sensors.
The activation process depends on whether the device is new or has been moved after a long period of inactivity. In the first case, you need to make sure that the packaging is intact and there are no external defects in the case. In the second, it is critical to wait a certain time before turning on the electricity so that the oil in the compressor flows into the crankcase.
This article describes in detail the algorithm of actions for safely activating your refrigerator. We will look at the nuances of working with electronic control, setting temperature conditions and checking basic functions. Compliance with these rules guarantees that Sharp equipment the period stated by the manufacturer will last without failures.
Preparation for the first start after purchase
Before connecting the device to the power supply, it is necessary to conduct a visual inspection and remove all shipping elements. Factory packaging protects the chassis and internal components upon delivery, but interferes with the proper operation of the ventilation system. Particular attention should be paid to the back wall where the compressor compartment is located.
If the refrigerator was delivered in a horizontal position or was simply tilted strongly when brought into the room, it needs “rest”. Oil from the compressor may have leaked into the system circuits, and it takes time to return. For models Sharp with inverter motors, this period can be from 4 to 8 hours depending on the angle of inclination during transportation.
Remove all adhesive tapes securing shelves and drawers, and also remove the protective film from the inner walls. Leave the doors open for the period of settling so that the smell of new plastic disappears and the temperature inside the chambers stabilizes. This will also allow you to check the tightness of the sealing rubber bands It is strictly forbidden to turn on the unit immediately after delivery if it was in a lying position. An attempt to start a compressor with oil in the refrigerant circuit can lead to water hammer and failure of the unit. along the entire perimeter
⚠️ Attention: It is strictly forbidden to turn on the unit immediately after delivery if it was in a lying position. An attempt to start a compressor with oil in the refrigerant circuit can lead to water hammer and failure of the unit.
Connecting to the electrical network and requirements
Refrigerators Sharp are sensitive to voltage changes, so the quality of the electrical wiring plays a key role. It is recommended to use a separate grounded outlet, without connecting the device through extension cords or tees. The cord length of modern models is usually about 1.5–2 meters, which allows you to reach the nearest power point without using adapters.
When turned on for the first time, an alarm indicator on the control panel may light up or a sound signal may sound. This is normal, as the temperature sensors have not yet detected the cooling of the interior. The electronic control unit will begin a self-diagnosis cycle, checking the condition of sensors and fans.
Make sure that the plug fits tightly into the connector and that the cable is not pinched by the case or furniture. If your network experiences frequent power surges, it is advisable to install a stabilizer or surge protector with an overload protection function. This is especially true for expensive models with a digital display and complex operating logic.
- 🔌 Use only a working socket with a grounding contact.
- ⚡ Avoid getting moisture on the electrical connectors.
- 🛑 Avoid connecting through cheap extension cords with thin wire.
- 🔋 If the voltage is unstable, use a power stabilizer.
Setting the temperature mode
After power supply and initial diagnostics, it is necessary to set the optimal operating parameters. In refrigerators Sharp control can be carried out through mechanical regulators or an electronic panel with a display. Models of the series SJ or SX are characterized by the presence of touch buttons that respond to a light touch.
The recommended temperature for the main chamber is +3...+5°C, and for the freezer - -18°C and lower. You should not immediately set the minimum values, hoping to cool the food faster. The unit will work hard, trying to achieve extreme performance, which will lead to increased energy consumption and noise.
If your model is equipped with the function Express Freeze or Super Cool, use it only when you need to quickly freeze a large volume of food. In normal mode, this function must be disabled for the system to operate in the economy cycle. Adjustment is made through the menu Temperature or by turning the knob.
Let the refrigerator run idle for at least 2 hours before loading food. During this time, the system will stabilize the temperature background, and you will be able to evaluate the real performance efficiency. If after 3-4 hours the walls do not become cold and the compressor operates continuously, it may be necessary to check the tightness of the system.
Checking the operation of the No Frost system
Most modern models Sharp are equipped with a complete system No Frostwhich prevents the formation of ice. The principle of its operation is based on the circulation of cold air through special channels. When starting up for the first time, it is important to make sure that nothing is blocking the air outlets inside the chambers.
The system automatically adjusts the humidity, so products may appear slightly drier than with older drip models. This is normal for technology Cool Air System. To compensate for this, use containers with lids or cling film to store vegetables and fruits.
In the freezer, check the operation of the ice maker, if provided by the design. It may take several freezing cycles to start the water delivery mechanism. Make sure that the water supply tube is connected and there are no air pockets in the system.
| Parameter | Normal value | Malfunction symptom |
|---|---|---|
| Temperature in the refrigerator compartment | +3...+5°C | Above +7°C or below 0°C |
| Temperature in the freezer | -18°C and below | Above -12°C |
| Compressor operating time | Cyclic (40% of the time) | Works without stopping |
| Noise level | Up to 40 dB (quiet hum) | Knock, whistle, vibration |
Diagnosis of possible problems at startup
Even a new device can exhibit strange behavior in the first hours of operation. Often users are frightened by the gurgling or crackling sounds that the refrigerant makes as it passes through the evaporator tubes. These sounds are absolutely normal for freon and indicate the circulation of the substance in the system.
If you notice that the side walls of the case are very hot, do not rush to sound the alarm. In modern models Sharp capacitors are often built into the side panels rather than located on the rear grille. Heating to 50-60°C in the area where the condenser is located is the normal mode of heat removal.
⚠️ Attention: If the compressor hums but does not start, or you hear a click and silence, immediately disconnect the device from the network. Repeated attempts to turn on may burn the starting relay or motor winding.
You should also pay attention to the uniformity of cooling. Place the thermometer in different corners of the chamber after 12 hours of operation. If the temperature difference is significant, check whether the door is pressed by a foreign object and whether the magnetic seal closes tightly magnetic seal.
☑️ Check after 12 hours of operation
Loading with products and modes work
The first loading should occur gradually. You should not fill an empty refrigerator that has just been turned on to capacity with warm food. A sharp temperature change will force the compressor to work at maximum load, which is harmful for the new unit.
Place products so that they do not block the flow of cold air. In models with technology Plasmacluster it is important not to clutter the area where the ionizer is located so that the air can be cleaned effectively. This will ensure freshness and eliminate unpleasant odors.
For long-term storage, use the correct packaging. It is better to keep liquid foods in closed containers, and meat and fish on the bottom shelf, where the temperature is usually the lowest. Maintaining product proximity will help avoid cross-contamination with odors.
What is Vacation mode?
Vacation mode allows you to switch the refrigerator to an economical operating mode. The main chamber can be turned off or run at a higher temperature (+15°C) to prevent mold while the freezer continues to freeze. This saves energy when you are not at home.
Care of the control panel and display
Refrigerator electronics Sharp requires careful handling. The control panel should not be wiped with a damp cloth or used with harsh chemicals. To clean, a dry microfiber or slightly damp lint-free cloth is enough.
If strange symbols appear on the display or it goes dark, try restarting the device by unplugging it for 10-15 minutes. This will clear errors in the controller memory. In some cases, it may be necessary to lock the panel from children, which is activated by a long press of the button. Regularly check that the software is up to date if your model supports the function Lock.
Please check your software regularly if your model supports the feature. Smart Home and Wi-Fi connection. Firmware updates can improve the compressor operating algorithms and fix minor bugs in the control logic.
How long should the refrigerator stand after delivery before turning it on?
If the refrigerator was transported vertically, 1-2 hours is enough to stabilize the temperatures. If it was lying or tilted strongly, you need to wait at least 4-8 hours for the compressor oil to drain into the crankcase.
Why does the Sharp refrigerator hum or click during operation?
The quiet hum of the compressor and periodic clicks of the thermostat are normal operating sounds. You may also hear the plastic cracking as it expands and contracts due to temperature changes. Loud knocking or vibration requires checking the installation.
What should I do if the alarm indicator is on after turning on?
The temperature indicator flashes until the internal temperature reaches the set value. This may take several hours. If the signal does not stop after 12-24 hours of operation, check the tightness of the doors and temperature settings.
Is it possible to turn on a Sharp refrigerator through an extension cord?
Manufacturers do not recommend using extension cords, as they can cause a voltage drop or overheating of the contacts. If you cannot do without an extension cord, it must be designed for a power of at least 2 kW and have a ground.
