I'm haveing a problem with my Rheem furnace(model # RGDG-050AUER)blowing cold air. Sometimes it blows warm air then cold again. The pilot light is lit and the fan blows but the burner doesn't ignite all the time. Any help/suggestions would be greatly appreciated.

Has anyone had an occurrence of a Laser 730 or 731 over firing?
The top of the heat chamber and the heat exchanger glow red on high when this occurs....
