Frigidaire Affinity dryer: Won't stop beeping.

So my dryer just started acting strange on me. It just keeps beeping, I’ve unplugged it for now.

What should I do now to fix/troubleshoot this problem?

Thanks for any help.

Edit - we just got behind it and replaced the long aluminum dryer vent tube. The thing was full of lint. I doubt that has anything to do with it, but just thought I would mention it

Any ideas on how to proceed?

Anyone have any clue or advice on this problem?

So this forum is dead
