Sudden significant change in fan noise

I don’t have a good feeling about this.

I cleaned the thing last week, but this is coming from the far left corner near the exhaust exit.

Any thoughts on next steps? Thanks.

There’s a fan at the exhaust exit as well - it sounds like that might need a more thorough cleaning!

That is an interesting noise! It is not the usual imbalanced fan noise we’re used to.

Can you try to take a couple photos of the exhaust fan for me? You can either post them here, or email them to us at support@glowforge.com.

It’s possible you’re fan needs cleaning. But I’d be more than happy to take a look at the photos you send to be sure.

Fan cleaning procedure

I have a method you can use to clean your fan.

First, you’ll need to obtain a can of 3M Novec Electronic Degreaser, which you can purchase from Amazon or Digikey.

That page will walk you through the cleaning process. Brief summary:

  1. Turn off and unplug your unit and move it outside. Make sure it’s in a location where it has power and Wi-Fi

  2. Using the fan maintenance page, you’ll be able to turn the fan on

  3. Following all manufacturer’s safety instructions from 3M, spray the degreaser into the fan while it’s running for approximately 5 - 10 seconds, or until the fan is clean.

  4. When you’re done cleaning, turn off your unit to stop the fan, and return it to its usual home. You should now see considerably better performance from your exhaust fan!

Please let us know if you have any questions!
