Why has my printer been making this sound?

[rough sky]

I’ve had my printer since April 18th of this year. About three months ago, it started making a specific buzzing sound only when I started a print. So i opened the back and started a test print and i heard that it was coming from this little black fan. I have a flash forge adventurer 5M.

ANOTHER ISSUE
My screen randomly switched from black to white after I accidentally bumped it off. When I put it back on, I noticed it had turned white. Once, I accidentally canceled a print because the buttons were inverted in color. Someone suggested I check the back cable, so I removed the back of my printer and saw that it was connected. I don’t know how to get it back to black.

It sounds like your fan has sucked a little peice of filament in it. If you tap or blow really hard into that fan(with your mouth not compressed air) you may be able to dislodge it.

As for the screen, not to sure. See if there is a dark mode option on your display settings maybe

When I tried blowing it, it made the same rattling sound it made before. I tapped it, but nothing seemed to come out. I thought it was just the printer, so I found this attachment that I can print and attach to it.

I believe other people are experiencing this issue too, not just me.

Blowing a fan is a good way to kill it. Pressured air can cause it to spin it so fast you damage the bearings and or burn the electonics
