Furnace Cycles
Have a 2013 Cougar 32RBK Xlite and the furnace burner cycles on and off while the blower continues to run until the set thermostat temperature is reached. Was wondering if this is normal?

Yes, there is a safety feature called a high limit switch that shuts the burner down if the heat exchanger gets too hot. But cycling on and off continually is not a normal operation for the furnace.
There are a variety of reasons for cycling, but the two most common reasons are restricted ducts and faulty limit switch.
