I am not sure anyone described the sail switch for the OP. The sail switch has to be blown closed by the fan before power is allowed to reach the rest of the furnace. If the sail switch sticks open, even a little bit, the furnace will not operate. A sticky one could fail to make contact with a small drop in fan speed because of slightly lower voltage. I hope this is helpful.
