My stove went down when sand entered the Acme Nut. The black Acme nut is designed to restrict the flow of propane to a set number of BTU's.There is also an excess flow valve inside the nut that will shut down if the hose ruptures. All this crap will go to hell if sand gets in.
Make sure there is no propane coming out the vent on the regulator.
Why does Pluto walk on all fours, drink from a dog bowl, and get treated like...a dog, while Goofy drives a car, wears clothing, and speaks in English?
