I have a nordyne model KG6RC 100C-20B furnace. Woke up this morning and the blower is not coming on. The red light on the circuit board is blinking twice in a row every few seconds. I found the code which reads-2 blinks. Pressure switch is open with inducer fan on. What is the best way to repair?

Remove hose from pressure switch and make sure of no restrictions or splits in the tube. Post back with results.
