I have a Goodman model #GOS80703AMA furnace. It's been through 4 IFC boards in about 8 years. Each for exactly the same faulty connection problem at the board. This makes me believe there is an open limit switch. I can make it run if I hold pressure just right on the plug. Any ideas? Thanks


Well I'm inclined to think the pressure switch is bad and would try replacing it since it should be cheap.
