with wiring similar to yours, I was able to get my fan to stop by going to the settings - schedule- fan (rather than temperature) and turn the fan off .

I found that my problem was also due to the common ground. Fixed that and it now works again

My second thermostat on my other furnace is not causing the fan to run. However I am getting a low battery warning. Both are wired the same.

Fan stopped when I removed display then started again after replacing it

I do have. C wire connection but the fan keeps running even though the heat is off. Any other suggestions?
