Narrative:

[Report] had been written up at least twice before. Maintenance fixed by changing parts. In climb with ice off received anti-ice duct warning followed QRH and closed 14th. Since icing wasn't a factor we didn't answer yes to any QRH questions and reached the end and closed the book. On final armed thrust reversers and they did not arm and we figured it out the QRH left out the associated important system loss. Opened the book quick applied malfunction 1.65 and landed. This needs to be changed! As far as the flight after initial malfunction stayed on west side of storms ACARS dispatch and received prompt message return to the departure airport. Meanwhile dealing with off and on nuisance warning from duct even though both ice protect was off (never turned on for entire flight actually) and 14th was closed. Diverting around weather and keeping my pilot monitoring busy with QRH briefing passengers maintenance; dispatch and operations. Let him go and got it done.not sure as the only thing that would've prevented this would've been a flight test as it seems the repeated ground fixes while according to maintenance was enough was insufficient.

Title: A CRJ-200 CAS alerted ANTI-ICE DUCT so the crew completed the QRH and closed the 14th stage bleed before returning to the airport for maintenance because of nearby icing and thunderstorms.
