Nest thermostat won’t turn off

[Catethegreat]

My Nest thermostat will not turn off the AC when the target temperature is reached. I have to take the panel off the wall for it to shut off. The apartment manager explained that the AC doesn’t support smart thermostats. Is there a way to fix this?

Hi @Catethegreat,

Thank you for posting in the community. I'm sorry to hear that you are having trouble with your Nest thermostat not turning off the A/C at the target temperature, and you have to take off the panel to stop it. Don't worry, help is here.

To gather the necessary information, please answer the following questions:

• What model of Nest thermostat do you have? This article might be helpful: How to tell which Nest thermostat you have.
• If possible, could you please provide a picture of your previous and current thermostat's wiring?
• What type of HVAC system do you have?

I'll be waiting for your reply.

Best regards.

Derick.
