Thanks for a comprehensive teardown, and here because I'm thinking of making a new control board for the Leovit. One thing, the article seems to fall short on one crucial point though, given that it's about replacing the motor, and that's where to get a replacement and details about the motor itself. Being pedantic, it also doesn't actually describe how to replace the motor, only how to get to the stage of being able to replace it.
Yes, where can we order the new motor?
Hello, thanks for the instructions, do you have a photo of the production label of the fan please? I can't read it. Thank you. John
Thank you for your instructions. Our Levoit 300 is making a high pitched sound. I've read on other sites to grease the bearings. Could you please explain how I can find the bearings and what they look like?
Thank you
I have same question. I have a high-pitched sound coming out of it and have read that I should lubricate the motor. Is there a way to do that without doing this complete teardown? And how and where do I do it?
