If it is still under warranty send it to them. The drag system is 22lbs and should be able to handle it. Can you be more specific on how it does not work? Does it disengage the spool? does the handle still turn? The reel has a carbon fiber drag stack. The resin could have melted. The reel should still work but with a locked up drag. If it got that hot it could have melted the nylon cage on the anti-reverse bearing and locked up the handle. Could have baked the lubricant in the bearings. As long as the frame and side plated are good it may be an easy fix.
I would send it somewhere and get them to take a look. A king on a setup like that is alot for the reel to handle. Nice fish though hope its hitting the smoker for fish dip
