Main stove burner only low flame

Any help would be appreciated.

The left front burner will light but not fully and will only achieve low level flame.

I was told it needs a left front gas valve at $220.

I can not find a part by that exact name, nor is it listed on the schematic by that name.

What i do see is description that says valve,burner 9755405 14K LF Plain Stem

I was wondering if that would be the part I am looking for.

I am asking as I think that is a major markup plus guy is saying I would have to wait between one and two weeks for this part.

If possible I feel I could get this thing faster .

As stated above any help would be appreciated.

The parts diagram shows there are three sizes of gas valve.
6, 12, and 14,000 BTU. Is this the largest burner that isn’t lighting right?

Have you tried cleaning the orifice and burner openings with a wire brush?

Have you checked the fit between the burner cap and the burner body. I’ve seen them warp and then they don’t fit together well or light well.
