32 degrees

I had this exact problem and it would return to normal at some point, maybe hours. One day it never came back, replaced thermostat NO CHANGE.
Inside the roof unit the cable from control board to thermostat (I had 2 connectors) is connected with standard phone connectors (RJ11). both Male and Female ends were badly corroded and no longer working. The moister in the roof unit just destroyed them. I expect this to be a recurring event so I’m getting the tool to fix them myself.
