Honeywell Air Purifier Will Not Turn On – Why And What To Do?

You know there is something wrong with your Honeywell air purifier if it won't turn on after you press the power button. That's why we looked for the reasons why this happens and what you can do to fix it. Here is what we discovered. 

If your Honeywell air purifier won't turn on, chances are:

  • the power cord is not plugged in or is damaged,
  • you have a faulty power outlet, or 
  • the circuit breaker tripped. 

Here's what you should do when you encounter this problem: 

  • Examine the power cord. Make sure it is plugged in and the electrical cord is in good shape. Pets may occasionally nip at a cable, blocking the flow of current. If the power cord is broken, get in touch with technical support to get a new one.
  • To test the outlet, try first plugging another appliance into it. Change the power outlet and confirm that it has the appropriate power rating if the new electrical device still won't switch on.
  • If the power outlet is operational, examine the circuit breakers and reset any that have tripped.
  • If you've checked all of those things and the unit still won't switch on, unplug it and reset the unit.

If none of those solutions work, ask for assistance from Honeywell customer support. They might be able to shed some light on the unit's malfunction for you.

Here are some problems you might encounter with your Honeywell air purifier and how to troubleshoot them. 

1. My Honeywell Air Purifier Stopped Working

Several factors could have caused your air purifier to stop functioning. These could include: 

Dirty Air Filter

The filter on your air purifier works very hard to purify the air. Your filter's ability to function will be compromised if it becomes clogged with dirt and debris.

Therefore, you need to make sure the filter is clean by checking it. In case it is very dirty, you might have to replace it.

Faulty Motor

The fan on the air purifier may be broken or not functioning at all. Therefore, you will need to swap out the blades for new ones, or if that doesn't work, locate an electrician who can make the necessary repairs.

Blown Fuse Or Accidentally Unplugged Power Cord

One or more fuses may be blown if there was an electrical surge or if your plug was unintentionally ripped out of the outlet.

Before you replace anything, it is worthwhile to check both potential solutions. Another option is to carefully reposition the cord such that no wires are overly strained when you do so.

Improper Installation

It occasionally happens that you installed your air purifier incorrectly. Therefore, you might want to check the installation before moving forward or ask our customer care staff for assistance.

Check that you correctly followed the installation instructions by reading the manual. It's worth checking to see if your model requires a special installation procedure because different Honeywell air purifiers have different installation requirements.

Unit Is Placed Near A Heat Duct

Your air purifier can overheat and shut off if it is placed too close to a heat duct. Consider placing the air purifier away from vents or other hot or cold sources.

Circuit Breaker Overload

One possible cause of your device not functioning properly is that you are short on power.

To avoid overloading the circuits in your home, be sure the amount of power provided by your outlet's current capacity corresponds to what you require. If you have any electrical problems at home that may have several causes, you may also get in touch with an electrician for assistance in making a diagnosis.

2. Honeywell Air Purifier Produces Strange And Loud Noise

Here is how you can diagnose the problem if your unit is producing strange and loud noises: 

Lower The Fan Speed

Put the fan's speed to a lower setting. Either the filter is put incorrectly, or it is blocked and has to be replaced. The quietest modes are turbo mode, generally clean, and germ mode.

Check Your Filters

You must replace the filters and then reset the timer if the "check filter" indicator light is on. Check to see if the filters are properly seated in the unit if you recently replaced them. The black pre-filter is held in place by the side tabs while the HEPA filters fit firmly into their compartments.

See If The Unit Is Properly Closed Or Has Foreign Objects

Make sure the cover is closed properly by checking. While operating, the device may vibrate due to improperly placed parts making noise. Look inside the unit for any foreign objects. A foreign object, for instance, could make a loud rattling noise inside the air purifier.

3. Red Light Is On And Won't Go Off

When this happens, it mainly indicates that you need to replace your filter. 

Lack of airflow to the equipment is another potential cause. The machine will automatically shut off if it doesn't have adequate airflow. Make sure the machine is in a well-ventilated area and that nothing is obstructing the air intake.

It's also possible that a bad power cord is to blame for this. And last, there's always the chance that the device is broken. If the device is broken, it might frequently or randomly shut off. If you believe this to be the situation, you should contact Honeywell customer care.

How To Reset A Honeywell Air Purifier?

You must press the reset button on your Honeywell air purifier's control panel to restart it. 

If a power outage shuts down the air purifier, try flipping the breaker switch off before turning on your air purifier again when power is restored.

If you have a Honeywell HPA 300 air purifier, you can restart it by following these simple steps:

  • For longer than three to five seconds, press and hold the "check filters" button.
  • Both the indicator light and the filter timer will restart.
  • When the pre-filter error light stops blinking, press and hold the "check pre-filter key."
  • Now the air purifier can function correctly.

Why Is My Honeywell Purifier Not Working Well?

Why Is My Honeywell Purifier Not Working Well

Even after operating the air purifier for a time, there are a few reasons why the quality of the air in the room does not improve. Here are some of them and how to fix them:

Too Big Room Size

Depending on the model, your air purifier unit can only effectively clean a specific room size. Any room larger than that will make the unit overwork and render the air in that room ineffectively clean.

Very Dirty Filter

You can clean the pre-filter and buy new HEPA filters to replace the old ones. When cleaning the pre-filter, just use pure water without any detergents or chemicals.

Blocked Air Intake And Outlet

Examine the air purifier's outlet and inlet, clear any obstruction, and wipe them off with a dry cloth to remove any dirt or debris.

Bad Indoor Air Quality

To lessen the amount of toxins in the area, ventilate the space before using an air purifier. Be sure to shut all of the doors and windows before turning on the air purifier.

The Unit Is Positioned In A Corner

Place the air purifier 3-5 feet off the floor, away from corners and obstructions like furniture, and close to the worst source of air pollutants to maximize efficiency.

Final Thoughts

There are a variety of reasons why your Honeywell air purifier is not turning on. But the main reason could be an electrical problem such as damaged power cords, faulty power outlets, or tripped circuit breakers. 

Although you can troubleshoot these problems yourself, when it comes to electrical problems, you should practice safety and let an electrician assist you in diagnosing the problem.

Calling a Honeywell customer care service for help is also a good option.
