Try Tn Q's suggestion. Let it run for 30 minutes or so, then dump heat while the smoker is still on (this is key. If you turn off the smoker when dumping heat, then the process starts all over). The smoker should then run at 140*. If you've given this a real effort, then you'll have to talk to Cookshack.
If you've got a real problem, hot smoking produces great sausage but may not be what you're after. Otherwise, I'd freeze the sausage, then try it again when the smoker is fixed.
Good luck.
