We investigate some cosmological features of the $\Lambda CDM$ model in the framework of the generalized teleparallel theory of gravity $f(T)$ where $T$ denotes the torsion scalar. Its reconstruction is performed given rise to an integration constant $Q$ according to what we point out more analysis. Thereby, we show that for some values of this constant, the first and second laws of thermodynamics can be realized in the non-equilibrium description. Moreover, still within these suitable values of the constant, we show that the model is stable using the de Sitter and Power-Law cosmological solutions.
