Does Refrigerator Fan Always Run?

The answer may surprise you. Refrigerators have a lot of features, and it’s hard to keep up with all the different brands and models out there. So in this blog post, we’ll answer one question – does the refrigerator fan always run?

You might be surprised by what we found! We’ve put together some interesting facts about refrigerators that will make you think twice before buying again. And if you’re in the market for a new fridge, don’t forget to check out our reviews on various refrigerator fans to find one that suits your needs best!

Does the refrigerator fan always run? No, It Doesn’t!

The fan doesn’t always run because it only runs when needed to cool down or maintain the temperature inside the refrigerator compartment—the fan functions to maintain the food’s desired temperature and keep the refrigerator from heating up.

The fan can run when one of these three events happens:

  • The doors are opened too often, letting cold air out all over the fridge compartment each time it’s open. This makes the motor work harder, and you’ll hear that high-pitched noise more often than usual.
  • There is a temperature imbalance inside your refrigerator because maybe somebody put hot items in there or something spilled on top of other foods, so now everything has cooled down much faster. At the same time, some things still need refrigeration before they spoil.
  • Your freezer needs defrosting, which means you’ll have ice buildup at home if this goes unchecked for too long! Also, your freezer needs defrosting to help cool down the insides, which means more work for your refrigerator.

Significant Changes in Temperature Matter 

The fan doesn’t need to be constantly running as long as there are no significant changes in temperature within the unit itself. If there is an increase in heat or humidity, it will turn on automatically without any input from us humans!

If your fridge has been turned off but still plugged into an outlet, then the chances are good that its cooling system will continue working even though it won’t be actively cooled by ice cubes anymore. This means minor wear and tear on components like fans, leading to longer life spans overall for your appliance!

For a refrigerator’s compressor (the thing responsible for cooling) to work, the temperature of an appliance needs to drop below 40 degrees Fahrenheit. This is why it’s crucial that you routinely check on your freezer and adjust its settings as required for the compressor to turn off.

Check on the Air Filters

Changing out air filters may be a good idea if they’re not doing their job or have been neglected recently! Change them every month or so with standard furnace filters–they can help catch food particles before they get into your refrigerator, which means less cleaning down the line!

Keep the Doors Closed

And, of course, you should always keep the doors closed to minimize airflow and temperature changes in your fridge.

Rinse the Condenser Coil

Some refrigerators have a condenser coil that needs to be cleaned periodically. This is usually located on top of your refrigerator and can typically be found with two screws in its back cover–remove these, then clean off any dirt or debris (i.e., leaves) you find inside! Be sure not to use water when cleaning it; use a cloth towel and wipe down the coils. If there’s too much buildup after doing this, call for expert help!

Bonus: Tips on Keeping It Running Smoothly

  • Make sure there is enough space inside the compartment so that hot air has some room to escape instead of staying trapped with all those cold items.
  • Don’t put too many warm or hot items together – they take up less space than ice cream, but make sure they’re not touching each other as well; another tip would be to try storing them on lower shelves if possible.
  • Clean spills right away (if only water spilled, you could wipe it up with a towel, but if anything is oily or sticky, you’ll need to use cleaner).
  • Keep the door closed as much as possible.
  • Clean off any debris from vents and the top of the refrigerator.
  • Don’t store items on top of the fridge – they take up space that cold air could be flowing through.


The answer to this question is not always as simple as it may seem. Many factors can determine whether or not a refrigerator’s fan will be running, but the most common reason a fridge runs its cooling fan without stopping is because of heat from food being stored in the freezer.

If you have noticed that your fridge has been on more than usual and are wondering what might cause it, consider having someone who knows about refrigerators to help diagnose the issue so you don’t waste any time getting repairs done before something becomes irreparable!
