If your pilot light is burning steadily but the main burners refuse to ignite, the issue is typically caused by a faulty gas control valve, an incorrect thermostat temperature setting, a malfunctioning thermal switch, or a blocked burner orifice. While the pilot assembly has enough heat to keep the thermocouple engaged, the control valve may be failing to send gas to the main burner when the thermostat calls for heat. Verification: Adjust the thermostat dial to a higher temperature setting and listen for the gas valve click to initiate burner ignition.
