Thanks everyone for the suggestions. Hottop customer service said I could replace their main board with my own and write a program, yeah right!
Ira, I understand your idea in principle, but not in execution. I guess I need to research how the sensor sends its data to the program board--if it's some sort of switch inline, I can easily trick it. The idea of using a vacuum to pull air through the roaster is probably the most practical, followed by Barry's idea of taking the front off and letting it cool with a fan blowing in the front. Will see how it goes--currently it takes about 10 minutes to preheat, 22 or so to roast, another 20 or so to cool, and then a few more to re-heat for the next batch. The re-heat can't be helped, but maybe the cooling can be reduced a lot. I'll report back when I have some data. bmc On Oct 24, 2010, at 6:10 AM, 187 wrote: > Would a blast of cold air on the temp sensor allow the cycle to start? > > On Oct 21, 5:01 pm, Benjamin McCafferty <[email protected]> wrote: >> Yeah, well out of warranty anyway.
