I have a problem with my Google Nest.

since this morning I get a error message h72 and the led on the heat link doesnt go on anymore.
reset of the heatlink doesnt work...

The system has been installed for 1,5 year.

Does anybody have any other ideas or do I need a new heatlink module?

Hello @Jurgen_de_hoogh! I'm sorry to hear that you're experiencing this issue, but I'm here to help. Could you please check and answer the following set of questions?

Have you recently had service or maintenance on your electrical, plumbing, or heating system?
Have you tried any troubleshooting steps before contacting us?
How many zones are present in your setup? Meaning how many thermostat you have.

Were there any power outages in your area recently?

Have you checked for all the breaker switches to be on?

Have you also tried turning them off and then on again?

If you press on the button of the Heat Link, it doesn't respond at all?

Hi Paul,
I have had contact with google Nest support and they asked all the options you mentioned to check. I have done all of them without any positive result.
I also checked what would happen when I insert a Micro USB in the heat link and than the LEDs light up. It doesnt solve the issue regarding the H72 error. I have to change the Heat link module (which is still under warrenty) only google doesnt have any in stock so I dont know when a replacement will be send.
in case you are able to see the cases it is logged with the following ID number

case-ID [8-4063000033271]

thanks a lot for your help.
