I've had a 3rd generation Nest learning Thermostat for 6+ months with no problem. In the last couple of days, It no longer works.
I am not able to control it at all but it keeps restarting (Google image appears) and the first message that pops up is regarding incorrect date and time with the option to set it. I can't make any selections and it quickly changed to the following messsge; Thermostat needs to restart. Be back in a bit. It then dies and the light starts flashing red. It will repeat this process every so often but it never actually resets.
I do have a c-wire connected but I charged it overnight just in case but it didn't solve the problem. I changed my filter and checked the fuse and nothing is blown.
I've tried resetting it by holding down for 10 seconds but it does nothing. Not sure where to go from here. Any help would be appreciated!
I called customer service and they identified that this is a defective battery issue. Ended up I order an replacement for the thermostat and wait for another 3weeks. And I’m not satisfied with the way they deal with replacements. Because they only have limited brand new product in stock, so you replacement could either be a brand new one, or a refurbished one. I’d say mostly like a refurbished one otherwise who gives that disclaimer. I even doubt the brand new one I got was a refurbished one. But anyways, the replacement is working fine now, but it will be my last and only Nest product I guess.
I am experiencing the identical problem as the user Meliss85. I have experienced no problems with my before now. It hasn’t worked for a little over a week. I thought it may have been no C wire. Due to when I got the Nest I was informed did not need one. However, a friend had indicated it might give me problems. So when this occurred I figured just get the wiring set up properly for it. However, that has not worked.
Your assistance would be greatly appreciated.
I reported the same issue here and and followed up by troubleshooting with a Google rep on Chat via the Google Help Center link at the bottom of this page. Took an hour before the rep finally conceded it was a unit issue. They replaced the unit under warranty (quick turnaround) and the new one is installed and working perfectly.
Yeah, there eas a faulty batter in my brand new unit. I had to jump through the hoops but they replaced the device for me.
There is 2 options when replacing…
1. Send in your defective divice and they will check it and then send you a new one. You will be without a thermostat during the period.
2. They will send you the new one first…but they put a hold on your account for the full amount. Once you return the old one the hold is removed. You only have like 10-14 days to send it back so keep that in mind.
they will send you a shipping label so you don’t have to pay shipping in either case
I am having the same issue now over a year now, I keep charging it manually because I thought it was the battery for sure. However charging it manually even overnight only charge the battery 25% and then it works for about 15-25mins then it’s show the ‘Restarting’ message. This is annoying me , and I had to use space heater during winter and now fans now that it’s near summer . Help !
