To relight an automatic pilot light, locate the control knob for the appliance, turn it to the “pilot” setting, and press and hold the knob while simultaneously clicking the igniter button. Continue holding the knob for a minute after the pilot light ignites, then release it and turn the knob to the “on” position. If the pilot light fails to ignite after multiple attempts, check for any obstructions or debris that may be blocking the gas flow or igniter, and consider contacting a qualified professional.
