So just to confirm, now your SV (set value - green) is 800 deg F, and the PV (present value - red) is 84 deg F ?

So looks like either the thermocouple is bad or connected incorrectly, or the heater isn't heating, or both. Is the furnace heating? If yes, then it's the thermocouple, connections, or controller or some combination of all three....

If the heater isn't heating, then it's the heater, SSR, connections, or some combination.

Ok I am formerly swensonknives on this forum. I couldn't get anyone to respond to my emails about gaining access again. But I'm back now and that is what matters. I replaced the relay and am running autotune again. I am hoping to get this oven to 1950 f max temp. It just needs to heat up and I will turn off when I am finished. When the auto tune runs I will post my settings for advice thanks.
During autotune should the oven temp be changing? The set temp on bottom is at 800.





Later Luke
