The flame sensor is a rather simple device located at the burner assembly of your heating unit. It's not much more than a thin, usually bent, metallic rod that sits in front of the flame stream inside the furnace. The purpose of the flame sensor is to confirm to the system that whenever the gas valve is open, a fire is actually present. When it fails it can cause a fire, keep your family safe. Call Air National Texas at 281-251-3143 to get you safety check scheduled. #fire #itcankill #heatercheck #staysafe #beready #ask #airnationaltexas #2812513143 #followus #stayinformed #always https://www.instagram.com/p/B3M4ittH_Q4/?igshid=mai03y2uby4z
