I ran a board through my planer and hit a wet glue pocket. now I have a burnt mess every time I run a board through. I scraped the glue off and used some steel wool but I still get the same burnt mess. I also tried paint thinner but it didn’t do anything.

How to I clean the glue off?

You might use a heat gun to warm the glue up, and then remove it.

I would guess that the “burnt mess” you are talking about is a brown streak in the planed wood when it runs through.
The only high speed roller of any type in the planer should be the cutterhead. So I am assuming that one of the other rollers is depositing the remaining glue onto the board AFTER the cut, since the cutters should clean it off if it was deposited by the rollers before the cut.

Goop is like thick airplane glue. I’d unplug it, and take a rag soaked with lacquer thinner and wipe off all the rollers after the cutterhead, making sure you rotate the system by hand to ensure you get all the area of the roller. You should see the offending brown in the rag.

Thanks for the responses. The Titebond 3 was burnt on the cutterhead. After cleaning it several times i decided to take the knives out and sharpen them (which I’d done reccently). I cleaned everything off real well and it’s working fine.

I can’t explain why the glue stuck to the cutterhead. Tennessee’s logic was sound. But, the glue wasn’t stuck to the outfeed roller like I thought it would be!
