Sonofresco and/or electrical engineering friends:
I'm getting an occasional (maybe once every 4 or 5 roasts) spike in temp that's causing the Sonfresco to shut down (it senses a fault.) The whole thing is exceptionally clean, from the chimney, to the thermocouple, to the chaff screen etc.
I haven't been able to see any burning chaff in the chamber, nor have I seen any evidence of it.
I'm leaning toward believing this is an erratic thermocouple, but it also happened on occasion with the previous thermocouple. (Both came directly from sonofresco.)
My question is, do you think it's a (another) sketchy thermocouple or could there be something else going on? I have a third thermocouple that I can swap out (also from sonofresco) but at this point, I'm thinking of getting an aftermarket. I remember some one posting in the sonofresco thread the equivalent that could be bought elsewhere.
Any and all thoughts and opinions will be appreciated.
Jim
