Receiving new household appliances is always an exciting moment, but the euphoria of the purchase should not overshadow vigilance. Checking the refrigerator after delivery is a critical stage that is often ignored, which subsequently leads to difficulties with returns or warranty repairs. Couriers usually perform only a superficial inspection of the integrity of the case, leaving the buyer the right and obligation to make sure that all systems are in working order.
It is in the first hours after unpacking that hidden defects that arose during transportation or manufacturing defects that are not noticeable during external inspection can be identified. If you discover a problem after a week of use, it will be extremely difficult to prove that it was not caused by your actions. Therefore, a competent algorithm of actions immediately after installing the unit is the key to peace of mind and safety of your finances.
In this article we will analyze in detail what components and parameters to pay attention to, how to properly carry out the initial start-up and what signs indicate a malfunction compressor or the defrost system. Compliance with these simple rules will allow you to either enjoy your purchase or promptly exchange the defective product without delay.
Visual inspection of the housing and equipment
The first thing where any diagnosis begins is a thorough external inspection. Even if you didn’t notice any damage when you accepted the goods in a store or from a courier, after unpacking all the layers of protection the situation may open up in a new way. Carefully examine the surface of the doors, side walls and plinth for items dents, scratches and chips. Pay special attention to the corners, since they are the ones that most often suffer from careless movement along flights of stairs.
Check the tightness of the fit rubber seals along the entire perimeter of the door. They should be elastic, without creases, cracks or signs of stretching. If the seal in some part does not adhere to the body, the tightness of the chamber will be compromised, which will lead to constant operation of the motor and the formation of ice.
⚠️ Attention: Any mechanical damage discovered after the signing of the acceptance certificate and the departure of couriers is almost impossible to prove as a result of poor quality delivery. Inspect the equipment before the service provider leaves the premises!
Make sure that all equipment is present: shelves, egg trays, bottle racks, instructions and warranty cards. Often small accessories are packaged in foam plugs or taped inside the cameras. Check the integrity of the glass shelves - microcracks may appear later due to thermal expansion.
☑️ Initial visual inspection
Installation rules and temperature adaptation
Before connecting the device to the network, you must comply with a number of technical requirements, ignoring which may result in denial of warranty service. The main transportation problem is the oil in the compressor. If the refrigerator was transported lying down or tilted strongly, oil could flow into the cooling system circuit. It takes time for it to drain back into the compressor crankcase.
There is a golden rule of exposure: if the unit was transported vertically, let it stand for 2-3 hours. If transportation was carried out in a horizontal position, the settling time should be at least 8, and preferably 12 hours. During this time, the refrigerant and oil will take their normal places, which will eliminate water hammer at the first start.
What will happen if you turn on the refrigerator right away?
If you start the compressor before the oil drains, the capillary tube may become clogged or the valves may be damaged. This will lead to expensive repairs, which the service center has the right to refuse, citing violation of operating rules.
Choose the correct installation location. The distance to walls and furniture should be at least 5-10 cm to ensure normal air circulation around condenser. Do not install the refrigerator near heating appliances or in direct sunlight, as this will cause the motor to overload.
Initial start-up and diagnostics of compressor operation
After the equipment has settled, you can proceed to the first start-up. Plug the power cord into a separate grounded outlet, avoiding the use of extension cords or tees. When you turn on, listen to the sounds: the starting jerk of the compressor should be short-lived, without a buzz lasting more than a couple of seconds or clicks.
In modern models with inverter motors start-up occurs smoothly and almost silently, while classic linear compressors can produce a more noticeable sound. However, in no case should there be any knocking, clanging or vibration transmitted to the chassis. If you hear strange sounds, immediately disconnect the device from the network.
⚠️ Attention: If after turning on the compressor starts and after a few seconds turns off, making a clicking sound, and this repeats cyclically, this is a sign of a malfunction of the starting relay or the motor itself. It is prohibited to operate such a device.
Let the refrigerator run idle (without food) for 2-3 hours. During this time, it must reach the set temperature. Periodically check the heating of the side walls - they may be warm, this is normal for heat dissipation. However, strong local heating or, conversely, cold areas may indicate problems with refrigerant circulation.
Checking the tightness and operation of the No Frost system
One of the most common problems is loose fitting of the doors, which is especially important for systems No Frost. To check for leaks, use a simple sheet of paper test. Clamp the sheet with the refrigerator door so that half is inside and half is outside. Try to pull the sheet out: it should be pulled out with noticeable force along the entire length of the seal.
If in some place the paper comes out freely, it means there is a gap there. You can also use a light source: place a switched-on flashlight inside a closed chamber in the dark. If light breaks through, the seal is broken. For No Frost systems, this is critical, since a constant flow of moist air will lead to ice fouling on the evaporator and failure of the defrost heating element.
Check the operation of the fans. In refrigerators with No Frost, when the door is open, the fan should stop (so as not to blow out cold), and when closed, it should resume operation. You can hear a change in noise or feel the flow of air with your hand by bringing it to the openings of the circulation system inside the chamber.
| Check parameter | Normal condition | Symptom of malfunction |
|---|---|---|
| Door seal | Tight fit, elasticity | Gaps, cracks, "waves" |
| Fan (No Frost) | Works with the door closed | Noise, creaking, lack of rotation |
| Heating walls | Uniform heat | Local overheating or cold |
| Water tray | Dry (in cooling mode) | Overflow or lack of water when defrosting |
Control of temperature conditions and functionality
A full check of temperature conditions is possible only after stabilization of operation, usually 5-6 hours after switching on. Use an external thermometer by placing it in a glass of water in the center of the refrigerator compartment. The standard temperature should be from +2 to +5 degrees Celsius.
In the freezer, the temperature should drop to -18 degrees or lower. Pay attention to the indicators (if any) and the operation of the electronics. All buttons, touchpads and switches should respond to touch clearly, without delay. Check the operation of additional functions: super freezing, ice maker, freshness zone.
Evaluate the noise level at night. Modern refrigerators operate very quietly, and extraneous sounds (gurgling, whistling, loud humming) will be clearly audible in silence. Gurgling is sometimes acceptable (freon flows), but loud mechanical sounds are a cause for concern.
Typical mistakes when accepting new equipment
Many users make mistakes that negate all testing efforts. The most common of them is fast loading of products. Do not fill an empty refrigerator with food immediately after turning it on. A sharp increase in temperature inside the chambers will force compressor to work hard, trying to cool the warm load, which can lead to overheating and breakdown.
Another mistake is ignoring the instructions for removing transportation bolts and clamps. In some models, the compressor or shelves can be secured with special screws or tape for transportation. If they are not removed, vibration during operation will lead to the destruction of internal elements.
⚠️ Attention: Keep the packaging (foam, boxes) for at least 14 days. If a hidden defect is discovered and it is necessary to return or replace the product by law, the seller often requires that the equipment be provided in the original packaging.
Do not forget to check the documents. Make sure that the warranty card correctly indicates the model, date of purchase and the store stamp. The absence of a seal or the wrong model can create problems when contacting the service center.
What to do if you find a defect after a week?
Immediately contact the store with a claim. According to the law on the protection of consumer rights, you have the right to return or exchange a technically complex product if significant defects are found within a specified time frame, but the sooner you do this, the easier the examination will be.
Frequently asked questions (FAQ)
How long should the refrigerator take to reach the temperature after the first turn on?
Usually, it takes 2 to 4 hours to achieve a stable temperature in empty chambers. Full stabilization and entry into the operating cycle can take up to 12 hours. If after 6 hours it is warm in the chambers, this is a reason to contact the service.
Is it normal for the refrigerator to make clicks during operation?
Single clicks when turning the compressor on or off, as well as when the thermostat is operating, is normal. The plastic of the case may also click during thermal expansion. However, frequent clicks accompanied by attempts to start the motor indicate a malfunction.
Is it possible to check the refrigerator if it was delivered in cold weather?
If the refrigerator was delivered at a temperature below +5 degrees, it should absolutely not be turned on immediately. It must stand in a warm room for at least 24 hours to warm up and evaporate the condensation inside the electronics and on the contacts, otherwise a short circuit may occur.
What to do if the refrigerator door is skewed?
Most modern models provide adjustment of the hinges. The kit often comes with a special wrench or hexagon. However, it is better to entrust the initial adjustment to the masters during installation, so as not to break the thread and maintain the warranty.
