Power connector not working

Just installed a new Nest Learning Thermostat 3rd gen. Had low Vin when cooling, and Google support said I needed a power connector since I didn’t have a C wire. After installing the power connector, I have low Vin and low Voc. Can someone help?!

Hello Oaklandc,

Thank you for taking the time to let us know about your inquiry. I'd love to know more about this.

Could you please share with us a photo of your Nest Thermostat's wiring setup? If possible, a clear picture of how you installed the Nest Power Connector would be helpful. You might have seen a wiring report on your thermostat. Check its settings and let us know the message code. Lastly, gather the power readings.

I'll look forward to your response.

Regards,
Mark
