I replaced the rear bearing and motor and it is still doing this. When I changed out the rear bearing it didn't make a difference. Changing out the motor made it not near as loud but it is still quite annoying and persistent. Any advice on what this cycling noise could be? It's accompanied by a vibration. I think it coincides with it being hot as well. Running it with no heat doesn't really make the sound.
