Issues- Replacement Nest Learning Thermostat

[gegetir]

Photos attached.

Received my replacement Nest Learning Thermostat yesterday to replace one that worked very well except for a Wifi connectivity issue. 

Upon connecting to the base, the replacement one first was blinking green and orange, repeatedly asking to be charged. We did both a base-charge and a USB-cable charge. 
It kept asking to be charged. So I left it charging on USB the whole night.

The charging error seems to be solved but now, it keeps asking me to remove the thermostat from its the base and reattach it again - repeatedly, non stop.

Lights are still blinking orange/green.

Is the replacement defective or am I doing something wrong?

UPDATES

It is now back to the ‘please charge your thermostat’ error message. It’s been only 15-20 minutes…

Hi gegetir, 

Yikes! Sorry to hear about that. Let's sort this out. 

1. Make sure that the wires are flat on the base. 
   • Detach the thermostat from its base and check that the wires lay flat on the base. Otherwise, the wires may be pushing the thermostat away from the base, causing the error message.
2. Loosen the screws of the base. 
   • Use a screwdriver to loosen the screws of the base by a half or quarter of a (counter clockwise) turn. This should help if the base is screwed too tightly to the wall.
3. Make sure the thermostat display is properly seated. 
   • Check the Nest thermostat from the side. If the white plastic from the thermostat base is visible around any of the edges, the Nest display isn't seated properly. In this case, reseat the display.
   • If the display doesn’t go any further, detach it from the base and check for loose wires or other obstructions that could cause the display to push away the base.
   • If necessary, take pictures of your thermostat base and wire setup to confirm that there aren’t any obstructions.
4. Check the 20-pin connector. 
   • Inspect the 20-pin connector for any visible damage. Check both the male and female ends on the base and display.
   • Make sure the pins are straight and in good condition.
5. Swap thermostat displays. 
   • If you have 2 or more thermostats of the same generation (as different versions of the thermostat have different base plates), you can swap the displays to check if this is related to the display or the base plate.
6. Reseat the wires. 
   1. Turn off the power to the heating, ventilation, and air conditioning (HVAC), and reseat all the wires.
   2. Make sure that the wire from the terminal is flush against the base, so the customer can properly seat the display at the base.
   3. ​Turn the power back on, and reattach the display to the base.
7. Perform a battery disconnect. 
   • Remove the display from the base.
   • Perform a hard restart on the thermostat.
   • While the display is detached from the base, wait for the thermostat to turn back on and display the message: "Please attach the display to its base."
   • Connect the display to the base and confirm that it starts back up. If the display tells you to charge it, have it connected to a micro-USB cable and let it charge for 10 minutes to an hour if applicable.

Let us know how it goes.

Best,

Zoe
