Nest thermostat gen3 battery failure

royalt — Thu, 14 Oct 2021 16:45:48 GMT

After a week of holiday I returned home, my nest gen3 was offline because it was out of power. After trying to load it with usb it only works a few hours. Resetting everything and emptying the netwerk settings don't help. Even if i reload with usb it looses power after some hours. There's enough voltage on the two cables, old "normal" thermostat works. I can only heat my house by clicking on the heatlink button. What to do? I already asked for a warranty yesterday but didn't get an answer yet.

I don’t have an answer but I would like to add that I am having the same problem. It’s been going on for some time.

I had the same issue. My original thermostat had a jumper between the RH/RC wires. The nest thermostat is supposed to jump the two internally but it doesn't. I had my red power wire connected to the RH and it was not providing enough power to keep the battery charged, so I swapped it to the RC and haven't had an issue since.

that's not it, i only have two wires (on/off). I now notice that when i load the battery with usb, the time the battery survives becomes shorter and shorter.

Same here, I'm thinking of getting a professional to come out.

I followed all the trouble shooting steps and had to contact google on monday to ask for a replacement. The new thermostat was delivered within 48 hours. I will have to send to first one back.

Can someone share the best way to contact Google for a replacement?
