Hi i have conquest 80 furnace    whenever the unit is turned on  even with the thermostat wiring disconnected   after a minute or so the draft inducer powers on and 10 to 30 seconds later the main blower starts and both remain running until you kill power to the furnace    


On the control pcb the ok and power leds are in continuously 

The flame led is off to start  then the draft inducer then after a delay it starts slow flashing  for about 6 seconds when it then starts fast flashing with the indoor blower starting

    Sounds like you have an open limit or flame rollout switch.

    You can choose to do what you want, but you cannot choose the consequences.
