The overwhelming majority of posters have indicated that their MT2 module felt warm, at best, to the touch. Now that you have posted that your MT2 feels hot to the touch suggests (at least to me) a need to replace your MT2 module.It was the module itself. After removing it, the receiver is not even warm on the module side. Before, it was rather warm to the touch after the module begin acting up.
What did Dish do when you called them with the facts?
