Ceramic Stove Tops
My sister told me that if you turn the burner on without a pot on the burner - it will damage the stove top. I typically turn my burner on a few seconds prior to putting a pot on for cooking so the burner will be hot and ready when I put the pot on it. Is this ok or am I really damaging my stove top?
These burners are thermostatically controlled and check the heat above them to regulate themselves, so if you leave them on for a long time without a pot, they can get very hot and stay that way, wear and tear on the burner thermostat. A few seconds doesn't matter- but I am betting it takes more than a few seconds to get it hot and ready?

Cooking at medium hot or lower makes these elements last longer.
