A new refrigerator in the house is always a joy, but also a responsibility. Many users are in a hurry to immediately connect their equipment to the network, without waiting for the recommended time. This can lead to serious breakdowns compressor, freon leakage or even refusal of warranty service. Why is it so important to wait a certain period? The problem is the oil, which flows from the compressor into the cooling circuit during transportation or tilting of the equipment. If you turn on the refrigerator immediately, the compressor will run “dry”, which can lead to overheating and failure.
In this article we will look at how long you need to wait before turning on for the first time in different situations: after purchases and deliveries, compressor replacement, long-term storage or prone transportation. You will also learn how to properly prepare a refrigerator for the first start, which models require special attention, and what to do if the equipment was turned on ahead of time. We collected current data for refrigerators Atlant, Samsung, LG, Indesit and other popular brands.
Why you can’t turn on the refrigerator immediately after installation
The main reason is oil in the compressor. During transportation, especially if the refrigerator was transported horizontally or at an angle, oil from the compressor gets into the refrigerant pipes. When switched on immediately:
- 🔧 The compressor operates without lubrication, which leads to accelerated wear parts.
- ⚡ Increases risk water hammer - when liquid freon enters the compressor cylinder.
- ❄️ The circulation of the refrigerant is disrupted, which is why the refrigerator may bad to freeze or not cool at all.
Manufacturers indicate the minimum waiting time in the instructions, but users often ignore these recommendations. For example, for refrigerators Bosch and Siemens with a system NoFrost it takes at least 4–6 hours, and for models with drip defrosting - up to 12 hours. This is due to the peculiarities of oil distribution in different types of cooling systems.
How long to wait before turning on: table by situation
The waiting time depends on how the refrigerator was transported and stored. Below is a table with recommendations for different cases. Please note: if the equipment was transported in lying position, the period increases by 1.5–2 times!
| Situation | Minimum waiting time | Features |
|---|---|---|
| Delivery in a vertical position (new refrigerator) | 2–4 hours | For models with NoFrost - 4 hours, for drip models - 6 hours. |
| Transportation lying down (on the side or back) | 8–12 hours | If you lay there for more than 2 hours, wait a day. Risk of oil getting into the circuit. |
| Replacement of the compressor or repair | 6–8 hours | The technician must indicate the exact period depending on the type of work. |
| Long-term storage (more than 1 month) | 4–6 hours | Before turning on, check the seals and the absence of condensation. |
| Transportation in winter (at temperatures below +5°C) | 10–12 hours | The oil thickens, it takes time to distribute it evenly. |
Critical error: turning on the refrigerator 30-60 minutes after delivery lying down. In 80% of cases, this leads to compressor failure in the first 3 months of operation. If you are not sure how much time the equipment spent in a horizontal position, it is better to play it safe and wait days.
Features for refrigerators of different brands
Manufacturers indicate different waiting times depending on the design of the equipment. For example, refrigerators with inverter compressors require less time to “sink” than models with linear compressors. Below are the key recommendations for popular brands: Liebert And Beko with inverter compressors require less time to settle down than models with linear compressors. Below are key recommendations for popular brands:
- 🔹 Samsung, LG (with
NoFrost): 4–6 hours for vertical transportation, 12 hours if lying down. - 🔹 Atlant, Indesit: 6–8 hours in any case (even if transported standing).
- 🔹 Bosch, Siemens: 4 hours for new models, 8 hours - if the equipment has been stored for more than 3 months.
- 🔹 Haier, Hisense: 2–4 hours, but at temperatures below +10°C - at least 6 hours.
For refrigerators with two compressors (for example, Samsung RB37J5230SA or LG GC-B247JLVN) waiting time increases by 20–30%. This is due to the fact that the oil must be evenly distributed in both circuits. Unless otherwise stated in the instructions, refer to maximum period from the table above.
⚠️ Attention: For refrigerators with linear inverter compressors (for example, Samsung Digital Inverter) inclusion ahead of schedule can lead to failure of the control program. In this case, the equipment will make uncharacteristic sounds or refuse to start.
Make sure that the equipment is level (check the level)|Check the integrity of the door seals|Leave the refrigerator alone for the recommended time|Connect to the network only after the waiting period has expired|Do not load products in the first 2-3 hours of operation-->
What to do if the refrigerator was turned on ahead of time
If, through ignorance or haste, you connected the refrigerator to the network ahead of time, do not panic. The consequences depend on how long the equipment has been running “dry”:
- 🕒 Up to 30 minutes of operation: unplug the refrigerator and let it stand 12–24 hours. Then turn it on again.
- ⏰ From 30 minutes to 2 hours: turn off the equipment, wait for the compressor to cool down (2–3 hours) and turn it on again. If extraneous sounds appear, contact service.
- ⏳ More than 2 hours of operation: high risk of damage to the compressor. It is necessary to call a technician for diagnostics.
Signs that the refrigerator was damaged by early switching on:
- 🔊 Loud hum or knocking when the compressor is running.
- ❄️ Bad cooling (the temperature in the chambers does not fall below +10°C).
- 💥 Frequent shutdowns due to overheating (thermal protection is triggered).
If you notice at least one of these symptoms, immediately turn off the refrigerator contact the service center. In most cases, changing the oil in the compressor or refilling freonhelps, but sometimes a complete replacement of the unit is required.
Is it possible to save a refrigerator if it is already broken?
In 60% of cases, the compressor can be restored by changing the oil and cleaning the system. However, if freon leakage or mechanical damage to the pistonoccurred, repairs will cost more than buying a new refrigerator. The average cost of replacing a compressor is 70–80% of the price of new equipment.
How to properly connect the refrigerator after waiting
Even if you have waited the right time, an incorrect connection can ruin all your efforts. Follow these step-by-step instructions:
- Check the socket: it must be grounded and withstand a load of at least
10 A. Do not use extension cords! - Make sure the installation is level: the refrigerator should not swing. Adjust the legs according to the level.
- Connect to the network: do not turn on the refrigerator immediately. Let it stand with the cable connected for 10–15 minutes (to stabilize the voltage).
- Turn on and configure: set the temperature
+4°Cfor the refrigerator compartment and-18°Cfor the freezer. Do not load products in the first 2 hours.
For models with electronic control (for example, Samsung Family Hub or LG InstaView) may be required after the first turn on sensor calibration. This process takes up to 24 hours - during this time the temperature in the chambers may deviate slightly from the set one.
⚠️ Attention: If the refrigerator is connected via voltage stabilizer, make sure that its power exceeds equipment consumption by at least 20%. For example, for a refrigerator with power150 Wyou need a stabilizer for200–250 W.
Frequent errors when first turned on refrigerator
Even experienced users sometimes make mistakes that shorten the life of the equipment. Here are the most common of them:
- 🚫 Ignoring the transport bolts: in some models (for example, Indesit ITF 118) the compressor is fixed with bolts for transportation. If they are not removed, vibration during operation will damage the unit.
- 🚫 Loading products immediately after switching on: the compressor works at the limit to gain temperature. Additional load leads to overheating.
- 🚫 Using non-original surge protectors: cheap extension cords can cause voltage surges that are dangerous for electronics.
- 🚫 Installation close to the wall: the ventilation of the compressor is disrupted, which leads to its overheating. Minimum gap -
5 cm.
Another typical mistake - incorrect temperature setting in the first days. Many people set it to maximum cold to “cool the chambers faster.” This leads to evaporator icing and increased load on the compressor. Optimal mode for the first 3 days: +5°C in the refrigerator compartment and -16°C in the freezer.
FAQ: Answers to popular questions
Is it possible to turn on the refrigerator after 1 hour if it was transported standing?
No, even with vertical transportation, the oil in the compressor has time to shift. The minimum waiting time is 2 hours, but for reliability it is better to wait 4 hours. The exception is refrigerators with magnetic suspension of the compressor (for example, some models Haier), 1 hour is enough for them.
What happens if the refrigerator is left unplugged for more year?
During long periods of inactivity (from 6 months), the oil in the compressor may thicken and the seals may lose elasticity. Before turning on:
- Check the rubber seals for cracks.
- Let the equipment stand 6-8 hours at room temperature.
- After turning on, do not load food into the first day.
If the refrigerator was stored in an unheated room (for example, on a balcony), the waiting time increases to 12 hours.
Do I need to wait if the refrigerator was transported in its original packaging?
Yes, even if the equipment was in the original box and was transported standing up, oil in the compressor it still shifts. The waiting time is reduced to 2–3 hours, but only if:
- The refrigerator was not tilted more than
45°. - The temperature during transportation was higher
+10°C. - The equipment was not subjected to shocks or vibration.
How to understand that the refrigerator is ready to be turned on for the first time?
Signs that you can connect the equipment to the network:
- The refrigerator has been standing in a vertical position for at least the recommended time.
- Room temperature - not lower
+16°C(if lower, the oil in the compressor may be too thick). - No condensation on the back wall (if there is, wait another 1-2 hours).
- Door seals are elastic, without cracks.
If in doubt, it is better to wait an extra 2-3 hours rather than risk a breakdown.
Is it possible to speed up the oil distribution process?
No, it is impossible to artificially speed up this process. Some “tips” from the Internet (for example, tilt the refrigerator in different directions or heat the compressor with a hairdryer) dangerous and can lead to:
- Oil getting into the refrigerant circuit.
- Damage to the pipes evaporator.
- Failure of the electronic unit.
The only safe way is to let the equipment settle at vertical position at room temperature.
