My furnace was acting fine until one day about 2 weeks ago. What happens is that the burner turns n as usual and heats up for about 10-15 minutes. Then the flame shuts off and the blower continues to run (blowing cold air) until I shut of off by the switch in the side. The metal box around the burner is too hot to touch. Could it be overheating for some reason. In order to start it back up, I have to push the reset switch and turn the switch back on. Then the issue occurs again. So far I have had the unit tuned up and the burner was changed out. Any siggesti Ha?
