OK appliance repair people, puzzle me this - red center light is lit, two temp lights are flashing green. Is this the secret Christmas tree mode, or something less stealthy?
@matt89134 apparently this is a failed controller issue. Interestingly enough those are actually hard to find. If you can follow this guide Cuisinart Griddler GR- 4N Knobs Replacement and post some good pictures of the controller boards with your QUESTION. Maybe we can find something that is out of whack :-) Adding images to an existing question
Thanks - fixed with big electronic cleaner spray bath on electronics.
