Broken furnace - Inspector responsibility?

[Rivy S.]

I recently purchased a property out of state. I had it inspected before the purchase, obviously, and the inspection turned up pretty clean.  Some renovations were needed, which were just completed.  During the final cleanup, the manager sent out the HVAC tech to clean up the furnace, and he discovered that the furnace's heat exchanger has several cracks which can't be repaired.  We are confident that this issue was present before I took ownership of the property, because since the closing there has been no gas supply to the unit, and the rollout limit switch (which had been tampered with) only trips when the flame distorts due to the cracks. 

Does the inspector have any responsibility in all this? A broken furnace would definitely have factored in negotiations on the property.
