Gas oven thermostat replacement
 

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 a

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. :)

its alright to use the old nuts.. the new ones probably cost about 2
cents each and the manufacturer just puts them in the pack which is
common with appliance parts.... the reason you had to replace it is
that you probably used Oven cleaner which ate the gaseous filled tube
that goes into the oven the sense the heat..... i would say that the
skinny one is for the pilot and is the thermocopler for the pilot.. the
heavier one is a sensor for the gas oven to tell the burner when to turn
off when it reaches 300, 400, 500 degrees or what ever you set it to..
i could be mistaken, it might be the skinny one might be for the oven..
just replace it like the old one and you should not have any problems...

Hi,

used the old nuts that were already attached to the

Yes there is a tool to cut the tubing.

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. Is that ok?

Along as they don't leak it is normally fine.

What are the 2 different lines leading into the thermostat?
I'm just curious why there are 2 lines, one larger than the
other.

One is probably pilot light gas feed and the other is main burner gas feed.

Makes me wonder if they were all flare fitting. Wonder if any of the threads
were straight nipple threads that woulda needed pipe dope?

Marc, did any of the fittings you remove have dried or still sticky goop on
the threads?

No, not that I can recall. The threads were clean. Should I be worried?

No goop on these threads, they are a compression fitting.
