What kind of breaker have you got? sounds like both 110 lines are coming off the same leg---
Start working your way back to the source(all the way to your main breaker---)
very strange-- ?
Well, no, because the power is 220 at the junction box and at the top two terminals of the thermostat....
Here is a BIZZARE twist.
So I started trying to figure out what would put the two legs back in phase with each other when it reaches the element. I tested the thermostat for continuity between the left side and right side bottom terminals and found a positive result - also, there is no continuity between the left bottom terminal and the left top...
I have the old thermostat that I took out before.. I test that for continuity and got the exact opposite result
Now, I tested both stats without any wires... is it possible that the new one is just simply wired backwards internally from the factory? Thereby switching the two 110 legs back into phase with each other? I am going to the hardware store to buy a new stat and test that.
