Hi @subhsoni!
Thanks for posting in the community.
I’m sorry for the inconvenience that you are experiencing with your new Nest thermostat when trying to activate cooling. Let’s solve this together.
To better assist you, I need some extra information. Here are some questions for you:
- What type of Nest thermostat do you have?
- When did cooling last work?
- What type of HVAC system do you have?
- Do you see any message in the display?
- Did you recently experience a power outage?
- What troubleshooting have you taken?
Check the next articles for further information: Troubleshoot strange heating or cooling behavior.
I’ll be waiting for your response.
Regards,
Daniel.
