Why does my Furnace go on and off every 10 minutes?
Off and on every 10 minutes is way too much. It’s time to replace the thermostat. There is a small resistor coil in thermostats called a heat anticipator. It fine tunes the thermostat on and off cycle so the furnace doesn’t run beyond or under the set temperature within two degrees +-.
