Cooling turns off suddenly

I installed a new Nest Pro Thermostat to replace on that seemed to be broken (unresolved Y1 wire issue) It seems installed properly. It is really hot in my house 90° and the new Nest is set for 71°. It starts cooling for a couple of minutes and then restarts itself after a timer countdown.

Hi @Saterry,

 

Thank you for posting in the community. I'm really sorry to hear that your new Nest Thermostat isn't cooling your home down and keeps restarting, especially with your house at 90°. It's certainly frustrating when you've already taken the step to replace the thermostat, and the issue persists.

The behavior you're describing, where the thermostat cools for a short period and then restarts after a countdown, sounds like short cycling or an HVAC system lockout.

The proper team would like to know more about your case and recommend a solution. We would appreciate it if you would fill out this form to contact us and find an answer.

Feel free to reply to this post when you complete it. We are happy to help you.

 

Best regards,
Kevin
