Why Is My GermGuardian Not Working?

There are various reasons your GermGuardian air purifier may stop working. They include the following, among others:

A Faulty Switch Or Fuse

Another electrical problem that you could have is with either your switch or a fuse. You will probably need to take it apart in order to fix this one yourself, but if not, then call in an electrician.

A Faulty Power Cord Or Plug Connection

Another cause of your GermGuardian not working could be either a damaged cable, especially if it has been bent too many times (which isn’t advised), or an issue with the wall socket’s connection to the mains supply. Again you might need to open up your device in order to fix this one yourself, but definitely call in a professional if you do not feel confident enough.

A Defective Filter Or Fan

If your GermGuardian stopped working because of either a faulty filter or fan, then it is going to be extremely difficult for you to work out how to fix this on your own. It might even cost more than buying a new device.

Motor Issues

Sometimes the motor in your GermGuardian can stop working. A motor will, in most cases, be an expensive thing to replace, so it is best to contact Customer Support in order to get it fixed.

A Faulty Power Button

Although not too common, another possible reason for your GermGuardian Air Purifier not working is because of a defective power button. While you can fix this yourself, it is advisable to let a professional help you out as it will be difficult to reach the button, and they can do a better job.

How To Clean GermGuardian Air Purifier

Carefully remove the pre-filter and give it a good cleaning with the brush attachment on a vacuum cleaner. You might want to use your user manual to know how to take everything apart.

Some models have a washable HEPA filter, but most don’t. So be careful, so you don’t damage the filter.

If your GermGuardian has a washable HEPA filter, you can clean it by washing it and then letting it dry. If not, don’t try to put water on or inside of it as this will damage it.

You want to dust off everything and wipe down the plastic/metal parts of the air purifier before putting the filter back.

How To Reset Filter Light On GermGuardian Air Purifier

To reset the filter light on most GermGuardian models, hold down the filter light button for five seconds and release it.

What Does The Red Light On GermGuardian Mean?

In most models, that light is supposed to be green. If it is red, it means it is time to replace the HEPA filter. In case you have already replaced it, reset the filter light by holding down the button for five seconds.

GermGuardian Fan Not Working

The fan may stop working due to:

A Failed Motor

If the motor is bad, then you will need to replace it. There is not much that can be done if the motor stops working on its own, but fortunately, your warranty may cover it.

A Faulty Fuse Or Switch

If your GermGuardian Air Purifier fan can also stop working because of a faulty switch or fuse. This might be a short circuit, in which case you can fix it yourself by replacing the bad component. In case this doesn’t work, then call in an electrician to help out.

A Blockage Of Some Sort

If there was a massive dust build-up where the fan blades are located, it could cause them to stop spinning. You should clean this out and see if that fixes the problem, but it may be a good idea to get in touch with Customer Support if you don’t know what you’re doing.

GermGuardian Air purifier Won't Turn On

GermGuardian Air Purifier Won’t Turn On

The first thing to check is your power source. If it is turned on, then the next thing would be to check the electric cord and see if it is properly plugged in.

You also need to check if there’s a red light. In most cases, that light will turn green when you press it and start working again.

Another thing you need to check could be the outlet itself, as faulty wiring might also cause your GermGuardian not to turn on. If this doesn’t fix anything, then perhaps one of the internal components failed, and that would mean calling a professional electrician for help.

How Often Should I Change My GermGuardian Filter?

The GermGuardian Air Purifier Filters are replaced every eight months. This, however, depends on how often you use the air purifier so, the frequency of replacement can go up or down.

If they’re damaged, then this might cause the air purifier to make unusual sounds. You should call in a professional electrician to fix this for you.

This needs to be removed before the air purifier starts working again.
