Error code 3 on countertop 2 rack bradley smoker

[bobandjudy2]

I keep getting an error code 3 displayed after the unit runs for a couple hours.  Kind of sporadic, but happens every 2 or 3 smoke runs.   I can not find a description of this error code.  What does it mean and how can I fix the problem.  Sure would be good to publish a list of these error codes.  I have the 2 rack countertop model smoker.

I would contact Bradley directly to resolve the issue, I know that there are no error codes listed in the manual nor are they online as far as I can tell. It is most likely the fan not operating or the bisquettes not being pushed forward. Other than the error code what problems are occurring?
