Dukane gas furnace no start

Dukane model MPGA100B4H. Blower runs as soon as power is applied. Draft motor does not run at all. Burner does not light. Pipes burst and sprayed all over it. Blower was running when this disaster was discovered. House is empty, so I don't know if the water put the furnace out, or the pipes burst because the furnace went out. On the other hand, how could frozen/bursting pipes be spraying water?

Welcome to the forums.

Look for the control board in the blower section. Hold the safety button in for the door and see if it blinks any faults. If just the blower is running..... you may have a safety limit open. You may have a bad circuit board if it got wet.
