Long shot, dryer is making weird noises - Leminal Space

It’s still drying fine as far as I can tell, the noises I attach here a recording of only happen around idk, 5% of the total drying time. They start, then stop again after a a few seconds or a minute, throughout the whole drying process. Mainly I was just wondering if anyone could imagine what it might be, what I could take a look at, or if it’s nothing to worry about. I understand it’s probably a long shot :D Thanks for whoever takes a look at this, here is the recording, first half is the noise, second half is normal running: https://gofile.io/d/RyWmFq [https://gofile.io/d/RyWmFq]
