I have 2 thermostat. Downstairs got hot, checked and it says no power. It has been hooked up for years, now suddenly no power. Checked breakers. Pulled power wire out and put it back. No help. Switched it with upstairs nest thermostat. It works upstairs, the one I brought down does not. Same errors. What do you think the problem is?
Sorry for the late response, but I wanted to drop in here to help.
I understand that these issues can be confusing but I definitely wanted to stop by and see how I could help.
Just wanted to double check to see if you were still needing help on this? If so, what troubleshooting steps have you tried?
Please let me know.
