The fan has been running all day even when the AC is not on. Can’t find a way on the thermostat to turn off the fan. Only display I see is to set the timer for 15 minutes but it wouldn’t shut off. The only way to turn it off is the breaker. Is there a compatibility issue?
You could do some troubleshooting to help:

@sporfrog, thanks for the help. What you've listed should cover the details that we need to check on the OP's concern.
@Th284, please let us know if you still need help by replying to this thread and we'll be glad to assist you.
If your fan is running all the time even when the G wire is disconnected, it most likely is the HVAC unit malfunctioning. If you pull the thermostat off of the base and the fan still runs, it definitely is the HVAC unit.

I'd like to check in here if you're still having the same issue with the fan running continuously. Have you tried to remove the Nest Thermostat from the base like what sporfrog has mentioned? Is it still running even if it is being removed? Also, let us know which Nest Thermostat you're using and if you have a G wire connected to it.
Thanks for your help, sporfrog.
Just wanted to jump in here to check to make sure that you saw our response. Please let us know if you have any other questions or concerns as I will be locking this in 24 hours.
Have a great day.
Hello Ryan I’m having the same problem, I just installed the nest thermostats few days ago, it’s was working well, till yesterday, the fan is running a least for the last 24 hours. I’m trying to turning it off trough the app unsuccessfully. HELP HELP I’m about to get the nest off and re install the old divise
We are having the same issue with fan running non-stop. It worked fine until a granddaughter messed with the thermostat and the heat setting was at 84 when I discovered it. We have tried a full reset and it is still running even with the fan turned to "off".
I have started facing this issue about a month after installation of the Nest Thermostat with c wire adapter. The fans continually runs if the thermostat is plugged in. For a month I had no problems.
when I remove the thermostat of the mount plate the fan stops. I also got the hvac unit inspected and the personal told me that it’s a fault with the nest and also checked that adapter if it’s sending power to the fan using the c wire adapter. Every looks good
is there a resolution for this ?
