Wolf R304 Burner Gas Valve Problem- Bonfire

[alylea]

Kon'nichiwa,

I have a Wolf R304 stove running on propane.  3 of 4 burners work fine.  The front left burner works fine on simmer/low.  On medium the outer ring lights and pulses.  When I set the knob to high, it's like a giant yellow bonfire with the flame about 12 inches tall. 

When I listen to the gas flow with the igniters powered off on the 3 good burners, it sounds exactly the same.  The bad burner sound like it's releasing crazy amounts of gas.  I'm think the valve is bad. 

Thoughts?

Sounds like bad or missing burner orifice. 

I believe each burner has two an inner and outer. They both need inspected and possibly cleaned or replaced.

Cool. I'll give it a try and see. Thanks.

So I checked the orifice and all seems good.  I disconnected the gas delivery pipe from the suspect burner and also from a properly working burner. Turning the valves on one at a time, there was an audible difference.  The burner giving me trouble sounds like it is being feed way more gas. I don't about the inner workings of the valves but Wolf valves have 2 outflow lines.  The small one feeds the simmer and main burner while the large diameter one only feeds the main burner.  The valve itself seems to have internal detents for low, medium and high settings.  It makes me think that the internal settings for the high position are defective, if that is possible.

Like 16345ed has said.   It sounds like your having an issue with the burner tube  Orafice.  Swap an orafice very carefully and see if that makes a difference ??   You may just have a bad orafice as ed has mentioned.   You also have not mentioned exactly what you have done to check the orafice.   I also believe if you are having an issue with a valve it will tend to more on the negative side of gas flow more than the positive side
