Check that the Fan mode is set to AUTO, instead of ON. If the blower fan continues to run after removing the front half from the wall plate (for at least 5 minutes after removal), this would indicate that there is a fault in the HVAC system, not the thermostat. Consult your local HVAC technician for service.
