What particular noise is happening when the dryer heats up?

It won’t allow me upload 2 videos. Is there somewhere I can send them?

If it will not upload the video or an audio file, we have a Reddit forum that can be used and it should allow the upload. Otherwise, a file link might work. Here is a link to our Reddit forum where I can be found. The username I would be found under is u/AppliancePro_William. https://www.reddit.com/r/AppliancePros/

Hot cycle 4 mins. Happens on any heat setting once it warms up

It sounds like the dryer is making a vibrating noise. Are you able to tell if it sounds like it is coming from a specific area of the dryer such as the front, bottom, top, etc?

Not able To determine where but it gets louder. Again only on heat setting. Air dry can run extended period without noise

When the motor was replaced, was there anything that may have been slightly loose or did the heating element coils look like they might be sagging a little bit?

We replaced the heating element too. Pretty much everything but the control board and rollers which are both being shipped. Blower fan looked fine barely any lint but we vacuumed out.

If you double check the heating element assembly where it connects into the heat vent, and at the front bracket, is there any wiggle at all?
