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
