No gas to cook top

"Dometic says it is an altitude issue!" This is nonsense, at 5400' Dometic doesn't have a product. Call again, insist on talking to a manager.

Is there a rubber hose unique to the stove top? Does it work again at lower elevation? It's possible something is blocking the propane in the line due to a faulty installation.

FYI RV documentation is known to be incomplete, misleading, generic for something else and downright wrong.

There could also be oil in the line to the stovetop blocking the flow.

According to the installation manual there is an internal regulator. A customer on Amazon stated that they used theirs over 10,000ft.

Dometic expressly told me there's no regulator at the stove. But I was looking at what you are! That's a regulator!

Here's the final dometic email!
Good afternoon,

I am sorry to hear you are not happy with your product. Unfortunately, this is a common problem with any gas product at high elevation. Due to the thinner air the gas to air mixture burns differently so we cannot guarantee use at higher elevations.

Wishing you a wonderful day,

LOL, not at you, but what a response.
Having spent alot of time at altitude far higher than that. Heck we lived at altitudes thousands of feet higher than mile high. I never began to run into LP altitude issues with things until over 10kft. And honestly, the only real problem I recall was with a Buddy Heater, up hunting.

Being a new camper, I'm more inclined to think its either a blockage in the line to the stove or a defect.
I guess that will vet itself out or not at lower altitude.

PS, that's still just the worst response ever by a mfg. They probably have their stoves in campers at dealers that sit at higher altitude than that!

So, from a technical point of view, how does the regulator at the stove work and how could it be affected by air pressure? The tank regulator reduces high tank pressure to about 11 psi I believe. Can that be affected by air pressure (I don't see how). Then at the stove regulator, how could air pressure affect that to restrict all gas flow entirely? Of course, air pressure at the burner would affect that regulator. As I've long understood, you must know how it works if you are going to fix it(aside from looking under the hood and jiggling wires!)

From a technical point of view, the propane gas pressure in a RV is regulated at 11" of "WATER COLUMN" not PSI...........Please don't adjust you own regulator.

Yes, I know that but misspoke. But I am attempting to diagnose the problem. In any adjustment I would use a manometer, Specifically, what does the regulator at the stove do? How is it affected by air pressure? What would shut down the gas to it at high elevation?

Have you considered that it could be defective? Just replace it.
