Re: Couple questions
After studying your diagrams a bit, I believe that your thermostat may not be calibrated properly. Since contacts 1-3 and 6-7 turn on when you set the dial to 150, it would seem that these are the ones you're looking for. Turn the temp setting down just a bit, or increase the heat on the thermocouple. You may need to put the thermocouple over an open flame for a short time. If 1-3 and/or 6-7 become open (element OFF) with the addtional heat, either one of them will work to cycle the contactor.
The variance in ohms is of no consequence. Either .1 or .4 is a small amount of resistance, and that's what you want through a switch, low resistance.
