I have two nest thermostats that will not run the fan only. Heating and A/C work fine and as expected. Just unable to run the fan on its own, only when heating or cooling is running. When I set the fan to run, the spinning fan icon appears on the thermostat, but the fan does not run.
My Nest wiring on both hvac systems are:
Y1 - yellow
G - fan
Rc - power
W1 - heat

I have looked at the article https://support.google.com/googlenest/answer/9296419 and yes, the thermostat is in temperature mode. All heating and cooling functions are working. It's just when I want to manually or schedule the fan to run in fan mode. The fan icon displays and is spinning, there are no errors, just the actual fan not running.
