Well this certainly had me saying 流口水的婊子和猴子的笨兒子, this is depressing, and in the "oh shit" department...
Well, the stove is back to working and the cause of the issue is kind of interesting... It was the regulator.
Now, as many years as I've been using propane, I've actually never had a propane cylinder regulator fail. Fact is, I can't ever recall anyone I know having a regulator fail...
Not too long ago we had a small accident (bent the pressure gauge) when changing propane bottles. Our regulator/pressure gauge looked sorta/kinda OK but we decided to err on the side of safety and replace the unit so trundled off to the hardware store and bought a new unit.
The new regulator worked for a few days and while making coffee the gas quit (just a quick observation here, but it would seem all propane/stove related issues aboard "So It Goes" manifest themselves while making coffee) and it appeared that we had run out of propane.
So we refilled the bottle and no luck...
Pulled the solenoid out of the loop and still no luck...
Decided it had to be the regulator so pulled the brand spanking new one off and went and replaced it. Still no luck!
So we assumed it was the stove and while everything seemed OK something had to be wrong with it because everything else had been replaced and it was the one constant.
But, stoves are really simple and even with a flame failure device on each burner there was no way that both burners would be out at the same time.
Something of a three pipe problem...
Back to square one...
We looked at the hoses... they were fine.
We looked at the solenoid... It happily clicked away every time we hit its switch.
Since we had not checked the bottle, we assumed it might be defective so we tried another bottle... The new bottle in the system did not fix anything.
It had to be the regulator but the regulator was brand new... Logic told me that it was the regulator but logic also told me that the chances of having two brand new regulators not work in a single week was nearly impossible...
We bought another new regulator but a different brand...
It works!

So it goes...
