Refrigerators are an indispensable household appliance. Damage to the device is a lot of trouble. And it's not just about expensive repairs. Significant downtime, especially in the summer, leads to spoilage of products.
As you know, more than 80% of faults occur due to the fault of the users themselves. To prevent this from happening, it is important to follow the recommendations of manufacturers, to listen to how the technique works. We will figure out how much the refrigerator should normally work, and how much - to rest.
Features of installation and connection of the refrigerator
When you brought a new refrigerator, no matter how you would like to immediately test it, do not rush. Let the appliance stand for several hours to adjust to the temperature in the room.
Free the product from packaging, remove everything extraneous. This can be film, cardboard, wrapping paper, polystyrene. Remember to remove the transport bolts.

How to install a refrigerator
Just as in the case of washing machines and other large household appliances, its operation and future operation depend on the correct installation of the device. With an incorrect installation, the technician will not fully fulfill the functions assigned to her.
Here's what you need to pay special attention to:
Do not place the refrigerator near heating appliances.
Adjust the legs so that the refrigerator does not stagger
- Install the appliance only on a perfectly flat surface.
- Check that the level is even. If necessary, adjust the feet so that the product does not stagger.
- It is forbidden to place the device close to heating and heating devices. These include heating radiators, stoves, etc.
- Do not place the device close to the wall.
First power connection
To protect the refrigerator from power surges, connect the household appliance through a special protective device “barrier”. It disconnects the equipment from the network if the voltage is higher or lower than the specified one. Such protective devices are much cheaper than stabilizers, but have one significant drawback: they turn off the equipment if the voltage goes beyond the specified limits.
Well, if network problems are extremely rare. But if the voltage jumps constantly, it is better to use a voltage stabilizer. The operation of such devices is fundamentally different from the "barriers". If the voltage is high, the stabilizer lowers it; if it is low, it increases. Thus, the equipment is powered by safe voltage and, most importantly, it can operate normally even during peak hours.

Important! When you first connect to the network, you should not fill the cameras to the top with products. The refrigerator should gain temperature gradually, so let it work for several hours idle.
How long does the refrigerator work until the first shutdown
The time of the first operation of the refrigerator can be different and depends on the temperature in the room, the volume of the refrigerator, the working volumes of the chambers, as well as the performance of the motor compressor and on which brand the manufacturer uses in this model of equipment. On average, this period is 2-2.5 hours.
How much the refrigerator should work, and how much rest then
Refrigerator cycle
Refrigerators operate in a cyclic mode. Moreover, the cycle consists of two periods: “rest” and “work”.
The latter provides for the operation of the motor and cooling the air in the chambers until the temperature reaches a predetermined value. After that, the compressor shuts off to rest. The air in the refrigerator gradually heats up, after which the compressor comes back into operation.
Household appliances can work with both frequent and rare motor shutdowns. If the device works with small shutdowns, this increases the rest time and leads to an increase in the duty cycle, which is not very good. Long-term operation of the motor leads to freezing of products, and a long idle time of the compressor causes the evaporator to thaw, resulting in the formation of ice on its walls.
Important! With an increase in the number of cycles, downtime and motor runtime will decrease. But due to the fact that the most power is consumed by the motor when it is turned on, the cost of electricity will increase.
That is, both situations are undesirable. What is the optimal compressor operating time?
Despite the fact that a lot depends on the operating conditions, the brand of the refrigerator and the working volume, there are special working time coefficients to evaluate the efficiency of the refrigerator.
The coefficient is calculated using the following formula:
K = Brts/ (INrts+ Babout), where inrts - the time of the working cycle, and Inabout - Time relax.
Consider the features of calculating the coefficient of working time by example. Let's say the device works for 20 minutes and rests for 30 minutes. We substitute the values in the formula: K = 20 / (20 + 30). After carrying out mathematical calculations, we obtain a value of 0.4. This figure is considered not bad.
In general, the lower the coefficient, the better. The permissible limits are 0.2–0.6. If the coefficient value is below 0.2, most likely you set the temperature to high and the device does not cool well enough. If a coefficient above 0.6 is obtained, the seal is probably worn out or another malfunction is observed.
How much time does the refrigerator work per day
The indicator will be more informative not per day, but the number of on / off per hour. In addition, it is not very convenient to attend to the operation of the device and conduct calculations for a whole day.
Important! An excellent indicator is if the refrigerator works with 4-8 starts per hour. Moreover, the duration of the motor is 2–4 minutes.
If the compressor turns on in an hour only 1 time - this is undesirable, and if the refrigerator does not turn off at all, then this indicates a problem. Perhaps the refrigerant has leaked, or the compressor is losing its capacity.
How long does the refrigerator work after defrosting
When turned on for the first time, the refrigerator works until it reaches the desired temperature. Operating time depends on the compressor model and the brand of refrigerant used, the condition of the door seal, ambient temperature. On average, this value is 2-3 hours, but it happens that 8 hours is not the limit.
