2017 would be new enough. I think you can reset the system by turning it off and letting it cool down and then back on.
I don't know alot but these units have a tube where the ammonia is heated and when it gets too hot it starts causing damage when the ammonia turns into crystals. You can read about it on the ARPRV website. Good luck.
