Fan won't turn off.

[markemory1]

Originally HVAC system was working fine. Installed Nest thermostat per the instructions and immediately the fan came on and will not turn off no matter what. Reinstalled old thermostat and fan turns off when HVAC is off like normal, put the nest back in again and same issue fan won't turn off. Help.

Hi markemory1,

Thanks for reaching out. I'm sorry to hear that you're having an issue with your Nest Thermostat controlling your fan. To isolation the issue, could you check if the fan would stop if you remove the display?

Thanks,

Edward
