How Long a Refrigerator Should Run and How Often It Should Turn On
Modern models start automatically, maintaining the set cooling level. Under normal conditions, the compressor turns on 5–15 minutes after shutting off and runs for 30 to 60% of the day. If you notice that the appliance works without stopping or, on the contrary, starts too rarely, you should check the temperature and the door gaskets.
Refrigerator Operating and Idle Time
Optimal refrigerator operating and idle time depends on the model, loading, and ambient temperature:
- in summer, the compressor turns on more often to compensate for heating;
- in winter, less often because the room is cooler;
- with tightly packed chambers, the motor will take longer to maintain the set parameters.
Refrigerator No Frost Operating Cycle
In appliances with a No Frost system, the operating cycle includes not only cooling but also automatic defrosting of the evaporator. Usually, the compressor stops for defrosting every 8–12 hours. After the process is complete, the appliance cools down again.
What Temperature in a Refrigerator Is Considered Normal
To keep food fresh longer, it’s important to know how many degrees a refrigerator should have to be optimal:
- in the main compartment — from +37 to +41 °F (+3 to +5 °C);
- in the fresh zone — about 32 °F (0 °C);
- in the freezer — 0 °F (–18 °C).
If you notice a high temperature in the refrigerator, check the settings and the cleanliness of the condenser. Sometimes, a refrigerator changes its own temperature — this can indicate a sensor or electronics failure.
First Startup and Preparation After Transportation
After transportation, the appliance must not be plugged in right away. How long should a refrigerator stand after transportation? Usually 4–12 hours so the oil in the compressor returns to its place.
During the first startup of the refrigerator, set the recommended temperature and let it cool down for 2–4 hours.
Shutdown and Restart
If the unit has been disconnected from power, it’s important to know how long you should wait before turning the refrigerator back on — at least 5–10 minutes to stabilize the pressure in the system. After defrosting, the appliance should operate without overload. Make sure it’s dry before switching it on.
How to turn on a refrigerator after defrosting: plug it in, set the temperature, and wait. And how long it should take to turn off after defrosting? Usually 30–60 minutes after reaching the set values.
When to Load Food and How Long It Takes to Cool
After startup or defrosting, the unit needs time to reach the right settings. Usually, a refrigerator reaches the proper cooling level in 2–4 hours, after which you can load food.
Don’t rush to fill the compartments right away: too many warm items will raise the temperature and increase the compressor’s load.
Refrigerator Lifespan
The average refrigerator lifespan is 7–15 years if used correctly:
- don’t place the appliance too close to the wall;
- regularly clean the back grille;
- monitor the temperature settings and don’t overload the shelves.
Summary
By knowing how often a refrigerator should turn on, how long it runs, and what temperature is considered normal, you can extend the life of the appliance and keep your food fresh. Monitor the modes, don’t neglect defrosting, and prepare the appliance properly for startup — and your refrigerator will serve you for many years.
