I am constantly getting the error e79 in my nest thermostat. When I remove the thermostat cover and put it back on, it temporarily fixes the issue. But again, after a few hours, I get the same error e79 again. I checked the wiring and it all looks good.
This has been happening for a long time and is getting very frustrating. Does someone have a resolution for this?
