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

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

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.
