The Frigidaire 318569904 burner control knob provides precise control over the heat level of a compatible cooktop burner. Designed to fit onto the burner control shaft, the knob turns the valve or switch to regulate gas flow or electrical power, allowing users to adjust the burner from low to high settings as needed. A properly functioning knob makes everyday cooking controls easier to operate and helps maintain the intended heat level. Replacing a cracked, loose, worn, or missing knob can restore proper burner adjustment and improve the appearance of the cooktop. This replacement component is designed for select cooktop models and should be checked for compatibility before installation to ensure proper fit and operation.
