Box Temperature Display Erratic

[oldfogey]

I'm having problems with my 5yr. old 3.5 D. When I tried to smoke some Buckboard bacon the box temp. screen started going up rapidly and then the high temp. alarm went off. I emptied the box, unplugged the meat probe and set the P2 program for a test. Same thing happened. My smoker is in my garage and has never been wet from rain. Is there a way to test the box probe or does this sound like a controller failure? My AH1 is set at 375 and AH2 at 250. I would appreciate any advice on my problem.

My first thought is to carefully clean the box probe and try again. As for a test of the box probe, all I can come up with is stationing a remote probe as close as possible to the box probe and see if they agree or not; just be sure that the remote is accurate for boiling water at your altitude above sea level.  It is not 212 degrees everywhere. Second thought is that the wood caught fire and the temp shot high. Other than that I would send Steve an email. Copy and paste your post and see what he has to say.

Thanks for the reply David. I did clean the box probe before running the P2 program. Since I was smoking bacon the wood was split into small pieces, but the element never got hot enough to even singe the wood. I will take your advice and email Steve.
