All, I figured out what happened to my furnace, not sure if this is
helpful. The problem with my situation was the safety door to the
furnace somehow came loose and the whole system stopped connecting to
power. This tripped the Rh power error message...
Did the technician fix it? What did they do? How do you even find a
technician that can help? Same issue e74 Rh wire and I'm on solar so not
sure about this or where to turn for help (except to a community like
this)
