Cook Surface is 500 Degrees on the Lowest Setting. Is there a Way to Lower it More?

I finally had my first cook. Did bacon fried rice. I had both burners on as low as possible and yet it was so hot I couldn’t keep up. Some of the bacon and veggies burned. Checked the surface temp and it was 500 all around. Is there a secret to get it lower like in the low 400s? It was really tough to cook with it that hot.
