Why is My Blue Air Purifier Fan Not Working?

You might experience that your Blueair fan works at first but quickly shuts down, or perhaps it makes a loud noise or doesn’t start at all.

In most cases, this is due to maintenance issues, and seldom, it is caused by actual fan or motor malfunctions. 

Now that you know the primary trouble areas for Blueair fans not working, let’s try some troubleshooting solutions.

How to Fix Blue Air Purifier Fan Not Working

Tip: Ensure you follow the troubleshooting steps below in order without skipping over any for the best outcome.

Solution #1: Clean Your Purifier Air Filters

The first thing to check whenever the Blue air purifier fan won’t work, is the air filters for signs of congestion.

If your Blueair air filters are obstructed, your fan will struggle to cycle through the air and purify it.

To fix this, you must thoroughly service your air purifier to ensure proper airflow.

Here are the steps to clean your Blueair air purifier filters thoroughly: 

1. Turn off and unplug the Blueair purifier.
2. Remove any side panels or filter covers to access the main air filter.
3. Carefully pull out the pre-filter and remove the primary filter.
4. You can use water and mild detergent to clean the pre-filter but don’t wash the main filter. 
5. Inspect the areas around the filters for dirt or blockages and clean them with a vacuum.
6. Allow the pre-filters to dry completely and then assemble the device in the same way you put it together.
7. Reinsert the Blueair primary filter securely.
8. Turn on and check the Blueair device for proper fan operation.

Note: Your air purifier should be serviced weekly, especially if your environment is dust-rich.

Solution #2: Check the Power Source for Issues

One typical reason why your Blueair purifier fan is not working or shutting off quickly is that it doesn’t receive sufficient voltage.

This can occur if your device is being used in an outlet that is overloaded or if the power delivery has issues.

Here are some steps to verify that your Blueair purifier power delivery and source are working:

1. Check the power outlet and confirm it’s fully functioning. 
2. Test the same power socket with another device to ensure the outlet is working.
3. Try a different power cord to eliminate cord issues – preferably one with a built-in circuit breaker.
4. Verify the power button is in the “On” position – if it doesn’t light up, it might indicate a defective unit.
5. Inspect the power cable for damage – look for signs of exposed copper or fraying.
6. Check the fuse or circuit breaker inside your home in case it gets tripped recently.
7. Lastly, try to connect your Blueair to a different power source.

Note: Blueair purifiers made for the US market work strictly with 120V power supplies.

Solution #3: Reset or Power Cycle Your Air Purifier

Sometimes, with regular use, the electrical circuit that controls the fan speed can malfunction due to a runtime software error.

To ensure this doesn’t happen to your Blueair device, you can perform a simple power cycling procedure to remove residual electricity.

Here are the steps to resetting your Blueair purifier to fix the fan controller: 

1. Power off the Blueair purifier and unplug it from the electrical outlet.
2. Wait for a duration of 10-15 minutes to allow the purifier to undergo a complete reset.
3. Plug the Blueair purifier back into the power source.
4. Turn on the power button and check for any obstructions in the vicinity of the purifier.
5. If the steps above don’t work for your exact Blueair model, follow the user manual’s specific reset instructions, if available.
6. Ensure there are no objects hindering proper ventilation around the purifier.
7. Monitor the Blueair purifier to assess whether the fan resumes regular operation after the reset.

Note: Don't place your Blueair purifier next to other strong household appliances that generate additional heat.

Solution #4: Check for Obstructions

If your Blueair air purifier has any obstructions on its exhaust ports or air intake vents, it can lead to problems with the fan working.

To prevent this scenario from affecting your air purifier, you must check these ports for any obstructions.

Here are the best ways to ensure your Blueair is correctly set without obstructions:

1. Turn off and unplug the Blueair purifier to ensure safety during inspection.
2. Examine the intake and exhaust vents for any visible obstructions.
3. Use a soft brush or cloth to gently clean the vents and remove any accumulated dust or debris.
4. Check the immediate area around the purifier for objects that might obstruct airflow.
5. Confirm that the Blueair purifier is placed in a location with sufficient ventilation.
6. Avoid placing the purifier near curtains, furniture, or any items that may impede proper airflow.

After following the steps above, continue by restarting the Blueair purifier and observe whether the fan resumes functioning without any obstructions.

Note: It's not advisable to place your Blueair in rooms that are too large, as this can reduce its air filtration qualities.

Solution #5: Firmware Update

As Blueair air purifiers are smart devices, they can be controlled through a dedicated app and also receive firmware updates.

If your device is running on outdated firmware, there is a slight chance that the fan controller might malfunction.

Here are some general steps to ensure your Blueair device is running the latest updates:

1. Identify the Blueair purifier’s model and serial number for accurate updates.
2. Download and install the Blueair Purifier app on your smartphone or tablet.
3. If your Blueair app is already installed, check if it’s running the latest version.
4. This can be done by going to the Play or App Store and typing “Blueair” in the search bar.
5. Check if an “Update” option is highlighted next to the Blueair app and tap it to install the latest firmware.
6. If powered off, plug the purifier back in, turn it on, and check if the fan begins operating normally after the firmware update.

Note: Your Blueair device will still be paired to your account after deleting or installing the Blueair app.

Solution #6: Check for Overheating

Sometimes, your device might overheat either due to an overly dusty environment or high ambient temperatures.

When this scenario unfolds, your device will likely turn off its air fan to prevent hardware damage.

To fix this issue, you have to check for signs of overheating.

Here is how to address any Blueair air purifier overheating to ensure normal fan function:

1. Turn off and unplug the Blueair purifier, allowing it to cool for at least 30 minutes.
2. Conduct a thorough examination for signs of overheating, such as a burning smell or discoloration, on the vents.
3. Check the surrounding temperature, ensuring the purifier is not placed in direct sunlight or near heat sources.
4. Wait for any thermal sensor to reset before plugging the purifier back in.
5. Power on the Blueair purifier and observe if the fan operates without signs of overheating.
6. Consider relocating the purifier to a cooler area if persistent overheating issues arise.

After performing all of the above steps, turn on your Blueair again and monitor the purifier for an extended period to ensure the problem is resolved.

Note: A Blueair device that has its fan malfunctioning upon arrival might be eligible for return or warranty coverage.
