Heatlink not powering up

stiphond — Tue, 10 Oct 2023 05:06:19 GMT

Hi everyone,

since a couple of days im getting an error on my nest thermostat 3. It seems the heatlink is broken and not powering up. Im reading this a lot on these forums and the conversation tends to go in private messages for a solution. I tried troubleshooting myself but not getting any further. From other posts I got this list of troubleshooting questions I already resolved;

Turn them off and then back on
Press on the button again and check for LEDs

Hi there, I managed to find the form, but it looks like the serial number is wrong. Can you please complete the form again, but make sure you put the serial number of the thermostat display? It should start with 09A.

Hi Larisa, the serialnumber provided is the serialnumber i got from the display of my Nest Thermostat.
