The exhaust fan comes on full bore when I power my Glowforge up and it never winds down. The lights will dim after a period of time, but the fan never slows down or idles.
It used to come on full blast right when it was powered up, but would slow down during head calibration, only going back to full speed when cutting materials. It would slow down again shortly after the cut was complete.
I’m not sure when this behavior started. I vacuumed out the exhaust port and checked my vent tube. I also disconnected my exhaust tube and fired it up that way. At one point, it would go back to normal after being unplugged for a few minutes and then plugged back in, but that no longer fixes the issue.
A staff member will likely need to look at your logs to see what’s up - but in the meantime if you could record a video with sound and post it to YouTube/Vimeo/etc. and then link that here it might help troubleshoot!
Hi @horn. I’m sorry to hear that you’ve been noticing the exhaust fan on your Glowforge running at full speed all the time. I was able to review the video, and to help us troubleshoot, could you send me a few photos of your exhaust system? Specifically, please include pictures of the following

Turn your Glowforge off
Open the lid
Using both hands, gently pull the printer arm towards you as shown below:
Hi @horn. It’s been a couple days since my response, and wanted to check if you were still noticing your exhaust fan constantly running at full speed. Feel free to send any of the requested photos and I’ll be happy to take a look. Thank you!
Thank you for sending over those photos. Both the exhaust fan and exhaust configuration look good. I had one of our Senior Tech Support Engineers review the video you provided and compare it agains the logs from your unit, and it looks as though there is an electrical failure within your Glowforge. Sadly, this is not something we can fix remotely and your Glowforge will need a repair.
I’m going to send you a separate email with full details on the next steps for getting this fixed for you. You should receive my email in a few minutes, but if you don’t receive it in the next 30 minutes please check your spam / junk mail folder. Once I know you’ve received my email, I’ll close this thread.
