My furnace wont turn on because of the ventor pressure switch wont stay open according to my brother in law. He took the hose of the motor and sucked on it and closed the hose off so that the switch stayed open then the furnace turned on. As soon as he let air in the hose the switch closed and the furnace turned off. He is thinking its the motor but he he is not sure. Anyone know anything about what it could be? I really dont want to buy a new one because this one is only 3 years old.
