The blower inside our house wont stop running. When the digital thermometer is set to 77 degrees F, it will only go down to 77.5 (always 1/2 degrees above the temperature setting. No matter what temperature setting we put it on, it will stop at .5 aabove the setting. For example if we set it to 76 degrees it goes down to 76.5, if set to 80 degrees, it goes down to 80.5. The house gets cold to about the set temperature. But the fan never stop. The thermostat is set on AUTO. What could be the problem why the fan wo'nt stop. The thermostat is new. Thanks

Check the wiring on the thermostat. Make sure the wire going to the "G" terminal is not touching anything else.

while you are in there checking wires you may want to completely remove the green wire and if your blower fan continues to run go to the furnace cabinet expose the green wire there and also remove that end, now if the blower fan continues to run replace the blower fan relay as it is stuck on. If in doubt call in a Pro for a service visit, they can usually use a few bucks to feed their families.
