I have a Comfortmaker furnace that is not cycling correctly. Model is NTG3075FBG1. The unit cycles OK until the burner turns on but then immediately turns off, the blower does not start at all. The burner will continuously cycle on and off without turning on the blower. I'm thinking the sensor that "tells" the furnace control to turn on the blower is faulty. Can anyone adivse?

Regards!
