Your home’s furnace is a complicated beast. Many devices control and maintain a steady gas flow and the means to ignite a flame. As simple as turning up the thermostat on a cold Ohio night, the individual parts
that control and maintain your heat sometimes need to be replaced. Your flame sensor is the part that ceases the spark in the igniter once a flame is established and the gas line is lit. Once that process is completed, the flame sensor sends a signal to the control box ending the electrical charge. Once the flame is lit, with a malfunctioning sensor, the flame will go out soon after. This will prevent the gas line from staying lit and thus, no heat.
Reasons Flame Sensors Go Bad
Cracked ceramic casing
Dirty, covered in soot or deposits
Poor electrical connection
Melted sensor from contact to flame
Poor original installation
