Nest 3rd Gen heat link dead

brianolo — Sat, 16 Sep 2023 21:27:29 GMT

Hello, my 3rd Generation heat link box is dead. I have been through all the supplied troubleshooting help including holding the button for 10 seconds for a reset. The unit doesn't respond at all. I've ensured it has power but no success. Nest serial number is 10BA01AC331901R2. Thank you.

Hi there. Sorry for the delay, but can you tell me if you tried to turn the power off and then back on from the fuse board?

Hello again. The nest at my mother's house has failed in exactly the same way. The Heat Link unit has power but it is dead. Serial 09AA01AC331901YJ It is always operated through my email account.

Thank you.

Thank you. And just to clarify, the Heat Link has no LEDs on it, right? Can you tell me if you tried to turn the power off and then back on from the fuse board?
