5 When the furnace is attempting to light look for a bright orange glow coming from inside the furnace it should be visible thru the cover panel louvres. If you don't see this, the igniter may have gone out; or possibly obstructed exhaust vent. If u see the glow and the gas will not remain lit, it's most likely a dirty flame sensor.
