A boiler control knob lets you change heating temperature, hot water temperature, and boiler mode. If the knob cracks, feels loose, goes missing, or won’t turn, you can’t control the boiler properly. Heating and hot water may not work as expected. Replace the correct knob to restore smooth control. It also makes the boiler easy to use again.
