Based on customer reports and repair data, this part commonly fixes these issues:
Check to see if the furnace blower comes on when you jump the control board contacts for the red (“R”) and green (“G”) wire terminals. If it does, then it's likely the wall thermostat is defective and unable to alert the furnace control board to turn on the blower. You will need to replace the wall thermostat to regain control of the blower.
