The Whirlpool WPW10639175 is an essential component for your gas range's burners. The orifice, a tiny nozzle that regulates the gas flow to the burner, is safely housed in a small metal residence. The burner base's orifice holder screws onto it, perfectly positioning the orifice to provide the best possible gas supply. Gas passes through the opening and ignites to produce the flame when you turn the burner knob. The safe and effective gas flow provided by a functional orifice holder lets you precisely control the flame size for simmering, boiling, or any temperature in between. Replacing a damaged or clogged orifice holder with the WPW10639175 restores appropriate gas control to your Whirlpool range, resulting in uniform heat distribution and optimal cooking results.
