Nest Thermostat

[kathywong]

I have Nest thermostat Gen 3. It has bern working well until one day my AC is off. I checked on Nest thermostat it showed green led blinking. I followed as in other instruction, tried to reset the thermostat as believed that it caused from software updated and froze. It still didn’t work. I open led the battery and unplug as an manual reset, still showing blinking green led but nothing showing on display.

Hi kathywong,

Thanks for posting and sorry to hear that your Nest thermostat is not turning on. Please take a look at this article about Troubleshoot when your thermostat won’t turn on, due it seems to be a power issue. 

Let me know how that goes.

Regards,

Axel.
