Nest Learning Thermostat not charging

[TeePaul]

Nest Learning Thermostat is not charging. Noticed this issues over a week ago.

When plugged to the charger, readings are:

• Battery - 3.915V
• Vusb - 5.01V
• Vin - 0.00
• lin - 200mA(c)

I've tried charging with different usb cables, plugs and sockets 🙂 - still I get a message saying something like the  thermostat may be turned off.

The thermostat was rebooted/restarted a few times but the issue still persist.

I was wondering if anyone had a similar issue and how or if it was resolved

Thank you

Hi TeePaul,

Thanks for reaching out to the community! I'm sorry to hear that your Nest Learning Thermostat isn’t charging as expected. Let's try to fix this!

Since you’ve provided power readings that seem related to the European ones, I’d like to confirm if this is correct. Additionally, I’d like to gather the following details:

• How long did you charge the thermostat?
• When did the inconvenience first occur?
• Is this a new installation?
• Did you receive any error messages on the thermostat display or the Nest app?
• Are the power breakers on, and is your home receiving power?
• When you charged the thermostat with a dedicated USB cable, did you get any light to blink?

In the meantime, I’d suggest the following steps: 

• Carefully remove the thermostat's display and check for bent connector pins.
• Verify that the thermostat wires are securely connected and all buttons are pressed down.
• Check the air filter. Your HVAC system requires good airflow to operate properly. A clogged or dirty air filter can restrict airflow over the cooling coils, causing them to freeze and shut down the system.

Please keep me posted.

Best regards,

Jenniffer

Hi Jenniffert,

Many thanks for your response

The readings are roughly correct. Below are the responses to your questions:

• How long did you charge the thermostat?

• The thermostat has always being plugged to electricity via USB to cable

• When did the inconvenience first occur?

• Noticed the thermostat was asking for charge despite being plugged in about 2 weeks ago

• Is this a new installation?

• No, this is not a new installation. Installation was in September 2016

• Did you receive any error messages on the thermostat display or the Nest app?

• No error message is visible on the app
• When the thermostat is not connected to cable , this message shows up  - "The power from your equipment to the thermostat may be off"

• Are the power breakers on, and is your home receiving power?

• Home is receiving power. Thermostat has been moved to another location in the house to try with another socket/plug and different USB cables but no improvement. Original/dedicated cable that came with the nest thermostat is charging other devices.

• When you charged the thermostat with a dedicated USB cable, did you get any light to blink?

• No blinking light showing on charge. I do however get green light blinking several times and one red light when I reboot the thermostat.

Thank you once again for looking  into this issue.

Kind regards
