Fan will not shut off while using the nest thermostat

[TonyStracuzza]

Hi there. Ever since I connected my new Nest thermostat, the fan has not stopped running. It’s been well over 2 hours. Anyone know a solution that works for certain?

I’m not getting the other issues that people seem to have with the C wire missing so I doubt it’s that. Any other ideas?

How is it wired?

Not having a C wire can cause the fan to operate when not expected

I don’t have a C wire but I am not getting the typical errors that other people who had the C wire issue were getting (ex. Low battery). Should I try moving the G wire to the C wire for now?

[Patrick_Caezza]

I never recommend using the G wire as a C wire.

Is there a spare wire by chance? If there is you can use it to create a C wire, or you can get the Nest Power Connecter which will create one for you.

I did the nest power connector and it worked thanks
