Hi all,

I have an Artistan with the TC4 set up on a West Bend Poppery I.

I was roasting a batch, and then all of a sudden, everything turned off. This has happened before, and I just simply need to restart the roast by stopping the log and restarting it again.

But now, I get absolutely no response from my roaster. THhe fan doesn't turn on and the heater doesn't turn on. BUT - I am getting temperature readings from my thermocouples in Artisan. I don't understand why I am receiving thermocouple outputs (which are accurate), and why I am not able to tell the heater or fan to turn on. Could I have tripped the temperature sensor and it just hasn't closed?

Does anyone know what could be the problem?

Last time I had this happen, I had to turn everything off (laptop computer / Windoze 7), and start over.
