Another dead Heatlink

Have two heat links. Already replaced one a couple of years ago at my own exoense. Now the second one has gone dead. All checks completed. These are clearly unreliable. Case opened over two weeks ago and have heard nothing

Hi Duffy1,

Thanks for posting in the community! I understand that your Heat Link units have stopped functioning—one was replaced a couple of years ago, and now the second unit has failed. It’s completely understandable that you’d have concerns about their reliability; I know how important it is to have your system working correctly. I appreciate you completing those checks and taking the time to contact us. I also apologize for the two-week delay in our response regarding your open case. No worries, I'm here to help!

To better investigate this, I’d like to ask for the following information:

What is the specific model and generation of your Nest Thermostat? Here’s a helpful article on how to identify your thermostat model.
When was the non-functioning unit installed?
Do you see a wiring report or error code on the thermostat or the app?
Could you please list the troubleshooting steps you’ve already tried?
Do you have a case number from your last interaction? This will allow me to thoroughly review the case history.

I look forward to your response.

Best regards,

Jenniffer

Por qué reemplazaste el anterior enlace?

Si tenía ya fallas, la versión antigua era mejor que intentarás otra conexión.

Ya que dices que contabas con 2 supongo que no eran las mismas. Hubieras intentado con una sola.

O en tu dispositivo es necesario tener 2 enlaces ?
