I see a lot of people have this issue-- is it a flaw with the google nest? I removed an old thermostat that was functioning properly but wanted to upgrade.
I do have a C wire-- it is blue. It is connected at the thermostat and on the motherboard of the AC/Heat unit
I did "restrip" the wire to make sure that the wire was fresh and making good contact.
The Nest Google I have has a mirror like face. It does not say learning or anything else.
Google Nest Thermostat "Snow"
I don't see a model number per se-- I do see a code which *may* indicate model? M: G4CVZ with a MFG date of 09/2023
It is supposed to ger very cold tonight. Can I run it temporarily without the C wire? even if I can-- what do I need to do to fix the google Nest Thermostat so that it functions properly?

Hi there Delvalle7.
Thank you for reaching out to our community.
Having your thermostat not recognize the C wire properly can be frustrating because it prevents proper installation. However, don't worry. I'm here to help.
My first recommendation is to rule out any issues with the C wire. Make sure the connected wire can provide a steady power signal.
If you're still in the setup phase, remove the batteries from the thermostat for 5 minutes and then try the setup again. When setting up, select the correct heating/cooling system you have. Choosing the wrong system type can prevent the Nest thermostat from detecting the C wire.
While you can make the Nest thermostat run without the C wire, it's not recommended. If your system requires the C wire for consistent power, your thermostat might lose battery power unexpectedly, especially during long heating or cooling cycles.
As a last recommendation, there's a possibility that the C wire in your unit isn't properly grounded, which could cause this error message. If that's your case and you're looking for long-term solutions, contacting a technician might be helpful.
Please keep me posted.
Regards,
Angel
