When your furnace turns on and off over and over, it is called short cycling. It wastes power and wears out your furnace faster.
Common causes
A dirty filter is a top cause. So is a thermostat in a bad spot, like near a heat source. Sometimes the furnace is too big for the home.
Try the easy fix first
Start by changing your air filter. A clogged filter makes a furnace overheat and shut off, again and again.
