Heat Pump TXV Failed - Aux Heat Coming On

Heat Pump TXV failure does happen and with a basic understanding of how the refrigeration system works, you can be sure that's the problem before replacing the part. I explain how and why I decided to replace the TXV and why its just simple elimination of the common denominators' to determine it. There is more than just airflow and the TXV that can cause low suction evaporator temperatures and I did not go into all the possibility's because they didn't apply to this system.
