3rd Gen Thermostat will not wake

KenF — Sat, 26 Nov 2022 12:37:42 GMT

I’ve owned my nest 3rd generation learning thermostat since 2019. This issue started in November 2022. I search forums and found a couple similar issues with locked threads but no solution.

My display doesn’t come on when I approach or touch it. The battery is fully charged and power within specs. I hear clicking and I can push and change settings like temperature and see it reflected in the phone app. After making changes and continuing to turn the dial and push in it may eventually respond. It will always start working if I hold in for 10 seconds and restart. This is not a power or battery issue and I’ve not found an answer in forums or other online resources.

I called an hvac pro, they came out and tested the wiring, line voltage, etc and stated everything is good to the thermostat.

Hey KenF,

I’m sorry to hear you’re having trouble with this. No worries, we'll check this out. Is the thermostat's display seated properly? Are all the wires of your thermostat seated firmly in its terminals (with no loose or exposed wires)? Could you check if you're able to control your thermostat in the Google Home app? If so, send us a screenshot of your power reading.

Thanks,

Archie

I ended up reaching out through the support form found in another post and they had me do a full reset and the thermostat display has been waking and responding for the past 13 hours.

Unfortunately, the full reset meant starting over with everything including seasonal savings but otherwise the thermostat display is responding.

I mentioned in the original post this is not a power issue, I did all of the basic troubleshooting and even had a hvac pro come out and test everything with equipment. But to answer specifically all wires are fully seated and the power has read consistently as follows the entire time I’ve had this issue. Also, I have never received low power alerts and I could control the thermostat through the app and google home.

Battery: 3.931V, Voc and Vin: 32.71V, Lin: 200mA

It has been 13 hours since I received the support message and completed the full reset. If the thermostat continues to respond today, I consider this resolved.

Thank you for responding and assisting.

I am still having issues with the thermostat and have been working directly with the nest support team around solution options. I will post if a solution is found.

The thermostat is being replaced with a new one, so I no longer need assistance. IT t seems it is a defective thermostat. Thank you.
