Making sure the furnace flame sensor is clean and in good condition not only prevents a furnace malfunction, but also ensures safety. If the furnace ignitor malfunctions, natural gas continues to flow through the furnace without the flame. The flame sensor shuts the gas off if it does not sense the flame. #furnacesafety #homeownertips #homeownership #furnacemaintenance #furnacetuneup #hvactechnician #onehourheatingandairconditioning #olathe | One Hour Heating & Air Conditioning of Johnson County

In 25 years I've never seen or observed an issue cleaning a flame sensor with any type of sand or emery cloth. Some claim it will leave a layer of glass and reduce the signal. I would love to see a video of this phenomenon. #hvac #flamesensor #residentialhvac #hvaclife #hvacsystem #hvacbusinsess #hvacservice #hvaceducation #hvacknowledge #hvacinstall #hvacmaintenance #gasfired #furnace | HVAC Know It All
