I have a Bryant 373LAV Furnace controlled by Totaline Thermostat p/n 0441. The system work fine but the blower fan comes on AUTOMATICALLY from time to time even with the Totaline Thermostat set of OFF. How do I program the blower to STOP turning on Automatically?

The unit will run the blower if you have a problem on the low voltage side of the system----- , loss of 24volt power from the transformer due to open limit switches, a faulty condensate pump or freeze stat on the evaporator coil. Count the blinks of the light on the control board, while looking through the small glass window on the blower door, It will give the code to what is wrong.
