Replacing refrigeration equipment is a process going far beyond simply buying new appliances in a store. This is a complex task, including correct calculation of dimensions, safe dismantling of the old unit, preparation of the premises and competent first launch. Errors at any stage can lead to damage to an expensive device or violation of the warranty terms, so the issue should be approached systematically.
Modern models differ significantly from their predecessors not only in design, but also in technical characteristics, type of refrigerant and installation requirements. If you are planning replace the refrigeratorit is important to consider that new cooling systems, such as No Frost or Full No Frost, require a special approach to placement and ventilation. Ignoring these nuances can negate all the advantages of the new equipment.
In this article we will analyze the entire path from the moment of realizing the need for replacement to the moment when the first chilled products appear in the new unit. We will touch upon the issues of recycling old equipment, the specifics of connecting to the power grid and setting temperature conditions for various storage areas.
Assessing the need for replacement and selection criteria
The first step is always to make a decision that the old unit has really exhausted its resource or has ceased to meet the needs of the family. Often repairs are not economically feasible if the cost of restoration exceeds 50% of the price of a new model. In addition, older models consume significantly more electricity than modern devices of class A++ or A+++.
When choosing a replacement, you need to pay attention to the type of compressor. Inverter models are quieter and last longer, although they are more expensive. It is also worth considering the possibility of changing the dimensions: sometimes it makes sense replace the refrigerator to a higher one or, conversely, narrower one, in order to optimize the space in the kitchen.
⚠️ Attention: Before purchasing a new model, be sure to measure not only the width of the kitchen doorway, but also the height of the ceiling in the hallway and elevator. Many modern two-chamber models have a height of more than 2 meters and may not fit into a standard doorway without removing the doors from their hinges.
An important aspect is the functional content. A freshness zone, the ability to quickly freeze or a water display - all these options affect the comfort of use. You should not chase the maximum number of functions if you do not plan to use them; it is better to invest in the quality of materials and the reliability of the brand.
Preparation for dismantling old equipment
The replacement process begins long before the movers arrive. The first step is to completely empty the refrigerator of food and defrost it. Even if you have a system No Frost, ice may have formed inside, which during transportation will melt and flood the floor or damage the electronics during transportation.
After defrosting, you should thoroughly wash and dry the internal chambers. This is not only a matter of hygiene, but also a way to prevent unpleasant mold odors while the old unit awaits disposal. It is better to remove all removable shelves and drawers and pack them separately so that they do not break when taken out.
☑️ Preparation for dismantling
If the old refrigerator is equipped with a water filter or a connection to the water supply (for ice machines), it is necessary to turn off the water supply valve and disconnect hoses. Prepare a container in advance to drain the remaining water from the hoses so as not to wet the floor. Also check to see if the unit has become stuck to the floor or walls due to long use.
Safe dismantling and disposal
Disconnecting from the power supply is a critical step. It is strictly prohibited to pull the plug from the socket with wet hands. If the outlet is located in a hard-to-reach place behind the refrigerator, use an extension cord or contact an electrician to temporarily turn off the power to the panel, especially if the wiring is old.
When removing equipment from the apartment, maintain the vertical position of the unit. The refrigerator can only be tilted at an angle of no more than 40 degrees and only to the sides, but not forward or backward, so that oil from the compressor does not enter the refrigerant circuit. Restoring the correct position of the oil after tilting may take up to 24 hours of inactivity before turning it on.
| Refrigerator type | Maximum tilt angle | Settling time | Transportation features |
|---|---|---|---|
| Single-chamber | up to 40 degrees | 4-8 hours | Less demanding for transportation |
| Two-chamber (No Frost) | up to 40 degrees | 8-12 hours | Sensitive to compressor shocks |
| Side-by-Side | Strictly vertical | 24 hours | Requires a wide freight elevator |
| Built-in | Depends on the model | 12 hours | It is necessary to dismantle the furniture frame |
The issue of disposal also requires a solution. You cannot simply throw an old refrigerator in the trash - this is a violation of environmental standards, since the insulating foam and pipes contain freons. Many stores, when purchasing new equipment, offer the service of removing the old device, often with a small discount. This is the most legal and safe way replace the refrigerator without problems with the law.
Preparing a place for installing a new model
While the old unit is being taken out, it’s time to start preparing the niche. The floor must be perfectly flat and strong to support the weight of the new device, which can reach 100 kg or more. If the surface is slippery (such as tile or linoleum), make sure that the feet of the new refrigerator have rubber pads or anti-vibration stands.
Ventilation is key to durability. The distance from the back of the refrigerator to the wall should be at least 5-7 cm, and on the sides - at least 2 cm. This is necessary for free air circulation and heat removal from the condenser. Built-in models require special ventilation grilles in the base and upper part of the furniture box.
Why can’t you place a refrigerator near a radiator?
The proximity of heating devices causes the compressor to work in increased mode, which leads to rapid wear of parts and an increase in energy consumption by up to 30%.
Check the condition of the outlet. It must be grounded and located in an accessible place so that, if necessary, the device can be quickly turned off. The use of extension cords and tees for refrigerators is not recommended, as they can cause overheating of the contacts and a fire.
Installation and initial startup
After the new refrigerator has been delivered and installed in place, do not rush to plug it into the network. Let it stand in an upright position for the same amount of time as it spent in a horizontal position during transportation, but not less than the time specified in the instructions (usually from 4 to 24 hours). This is necessary for the oil to drain into the compressor.
The first start-up is best done without loading food. Start the unit, set the temperature to medium and let it run idle for 2-3 hours. During this time, you can check the tightness of the door seals, the absence of extraneous noise and vibrations.
⚠️ Attention: If after starting you hear a loud hum, gurgling or knocking, immediately disconnect the device from the power supply. This may indicate a shipping or defective item. Continuing to operate in this mode will cause the compressor to burn out.
To check the tightness, you can use a simple test with a sheet of paper: hold the sheet between the door and the housing and try to pull it out. If the paper comes out easily, it means that the seal is not tight and requires adjustment or replacement. Quality The seal is the key to saving energy.
Setting modes and loading food
Modern refrigerators are equipped with electronic controls that require initial setup. This is usually done through the control panel on the door or through a mobile application, if supported Smart Home. Set the temperature recommended by the manufacturer: usually +4°C for the refrigerator and -18°C for the freezer.
You should load food gradually. Do not immediately place hot or warm food - this will put extra strain on the cooling system. Place shelf-stable items first, then gradually fill the shelves. This will help the cameras reach operating mode faster.
Check the operation of the defrost system regularly. In models with a drip system, water should flow into the drainage hole and evaporate. If you notice a puddle under the refrigerator or ice on the back wall, the drainage hole may be clogged, and it needs to be cleaned with a special brush or soft wire.
Common mistakes when replacing a refrigerator
One of the most common mistakes is ignoring the operating instructions. Users often rely on the experience of using the previous model, forgetting that technology has changed. For example, an attempt to quickly defrost No Frost using a hairdryer can melt the plastic parts of the evaporator.
Another mistake is installing the refrigerator close to the wall or in a niche without gaps. This leads to overheating of the compressor and shortening the service life of the device. Also, many people forget to fix the shipping bolts (if any) or, conversely, forget to remove them before turning them on, which causes strong vibration.
You should also not neglect the noise level. If the new refrigerator is louder than the old one, check whether it is touching furniture or walls. Sometimes it is enough to move the unit a little or adjust the legs to eliminate resonance.
How long should the refrigerator sit after delivery?
The settling time depends on the temperature outside and the position during transportation. If the refrigerator was transported in winter, it needs 3-4 hours in a warm place to warm up. If he was lying on his side, the settling time is equal to the time spent in a horizontal position, but not less than 4 hours. For Side-by-Side models, it is recommended to wait a full 24 hours.
Can a refrigerator be placed on a heated floor?
Manufacturers do not recommend installation on heated floor systems. Constant heating from below disrupts heat exchange, increases energy consumption and can lead to compressor failure. If there is no alternative, use a thermal insulating backing under the legs.
What to do if the new refrigerator does not fit into the doorway?
In most cases, you can remove the doors from the refrigerator itself (the hinges are usually removable) or temporarily dismantle the interior door. As a last resort, for built-in models, it may be necessary to remove the furniture box if it was assembled around the old unit.
Do you need to wash the new refrigerator before use?
Required. Factory dust, remnants of packaging materials, or a plastic smell may remain inside. Wipe all surfaces with a weak soda solution or a special household appliance cleaner and let dry before turning on.
Why does a new refrigerator make strange sounds?
Gurgling, clicking and quiet humming are normal sounds of the refrigerant and compressor operating in modern systems. The alarm should only be sounded when there is a loud knock, grinding sound or vibration transmitted to the furniture body.
