Why does my thermostat say cool on but not working?
If the “cool on” or the snowflake icon is flashing, the thermostat is in delay mode, which can take up to 5 minutes. If the thermostat indicates a call for cool, verify that the furnace door is securely closed and that the power switch on the furnace is set to On.
Why does my thermostat keep changing the temperature?
Why? Because constantly changing the set temperature on your thermostat causes your air conditioner and furnace to stop and start, which causes them to run inefficiently. For example, let’s say you have your thermostat set at 68°F in the winter. Your furnace heats your home until that point then shuts off.

What happens when you set your thermostat to 68?
By setting the temperature to 68, your AC will end up having to run longer to hit that desired temperature, costing you more money to cool your home. The same is true for heating. To avoid paying more, don’t set your thermostat beyond your truly desired temperature.
