The Samsung Range-Stove Burner Knob, crafted from stainless steel, serves as an OEM replacement specifically engineered to adjust burner heat on Samsung ranges. This knob features a diameter of 2-3/8 inches and a width of 1-5/8 inches, with a shaft protruding approximately 1/8 inch from the rear side. To replace the knob, remove the existing one, align the shaft, and firmly attach the new knob onto the post. It is designed for use with select Samsung models.
