Hi Madge,

Yikes! I'm sorry to hear that your thermostat is still not working though has been charged for hours. Let me take a look at this for you. A few questions:

Are you located in North America or Europe?
What type of Nest Thermostat do you have?
When did this first occur?
What is the make and model of your heating, ventilation, and air conditioning (HVAC) equipment?
Are the power breakers on, and do you receive power to your home?
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)?
Are the connector pins of the thermostat display bent?
Are you using a micro-USB cable to charge the thermostat?
Have you tried to charge the thermostat with a different micro-USB cable or a different adoptor?

I'll look forward to your response.

Best,

Zoe

Thank you so much for your reply as I’ve been so worried about not having heating and I am so reliant on my nest

I’m in Europe, uk, Shipston-on-stour,

CV36 4FD

I have 3rd gen learning nest and my combi-boiler is only 2years old

My nest thermostat is on a stand and on usb charge for the last 3 days but still blinking red!

I have normal power here as everything is working ias expected

I don’t have air con as that’s not something we usually have here domestically

Yes I have tried several different cables including ones that work and tested charging other devices

If theees anything further you need to help

Me please let me know

I look forward to hearing from you

Hi there, thanks for the answers. Can you please try to take the display of the thermostat off the base and put it to charge for 90 minutes, directly with a micro-USB cable from a power socket?

Let me know how it goes.

I’ve tried this for longer than 90 mins now and sadly there is no change

Did you try different cables?

Re: Blinking red light for hours

Madge — Tue, 17 Oct 2023 18:50:48 GMT

Yes I’ve changed cables which I know work as the charge up the other devices

it appears to be that the power is going through as it blinks while connected with any cable used so this suggests to me that the device is faulty

Thanks for checking. To confirm, you took the display off the stand when charging it separately, leaving the ring that allows it to snap onto the stand with its micro USB cable attached to the stand, correct?

Did any message at all come up on the display when charging it separately or just the LED at the top came on occasionally?

To log a few more details:

1. Do you have more than one thermostat?
2. Is there a wiring report or error message on your thermostat and/or app?
3. Has there been any recent work done on your thermostat(s) or heating system?
4. Were there any power outages?
5. Were there any modifications to the internet configuration (for example: added extenders)?
