I have a miller furnace. It runs on LP gas. It comes on the ignitor comes on the burners see to light but the blower won't come on. Is this the mother board? I have replaced this in the past. The ignitor was burned out and I replaced it. I still can't get the blower to come on.

Without being there that would be my guess , but I wonder what's causing this to happen?
