I replaced my gas oven thermostat yesterday. The job was easier than I thought it would be and I have some questions after the fact. 1)After turning off the gas and unplugging the electric cord, I took off the knobs and front of the oven to expose the old thermostat. I simply unscrewed the 2 nuts that attached the 2 lines into the thermostat and removed the old thermostat, put the new thermostat into place and reattached the 2 lines. I than put everything back together. My questions are: The new thermostat came with 2 new nuts but I simply used the old nuts that were already attached to the existing lines. I didn't know if a special tool was required to crimp the nuts to the lines and they appeared to be secure. Is that ok? And
What are the 2 different lines leading into the thermostat? I'm just curious why there are 2 lines, one larger than the other.
Any response to my questions would be greatly appreciated so that I can put my mind at ease that my house won't blow up from a gas explosion. :)
