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?

Circuit breakers are a safety feature, but if you are relying on a breaker to pop every five minutes you are relying on the last layer of protection, and are not safe. What happens when the contacts of the over temperature switch weld themselves together from excessive cycling?
I have never seen that(40years). What usually happens on a Hi Limit that has too much duty, is, it stays OPEN and the furnace will not heat. The Bi Metal inside finally gives up and the default is to NOT make a closed circuit. Doug
