I apologize for the slow response. After taking a look at the video and the photos the fan appears to be functioning normally. The laser produces smoke and fumes which can result in particulate building up on the fan. This can cause the sound of the fan to change slightly. When this happens you can use our cleaning procedure to remove this build up.
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:
Turn off and unplug your unit and move it outside. Make sure it’s in a location where it has power and Wi-Fi
Using the fan maintenance page, you’ll be able to turn the fan on
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.
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!
I am going to close this thread for now. If you have any more trouble, please start a new thread or reach out to us at email@example.com.
