NEST HEAT LINK - suddenly stopped working, no led on the heat link

joannamd — Mon, 26 Jun 2023 07:42:25 GMT

Hi,

I just woke up to my boiler going crazy, and my thermostat showing the error message H72.

I have checked heatlink and have tried to restart it, but there is no light indicating that it is actually working. It has never happened to me before, I have no idea what I should do

Hi there @joannamd ! I'm really sorry to hear about this, but I'll do my best to assist you. Could you please answer the following questions and try the troubleshooting steps?

What type of Nest Thermostat do you have?
Are you seeing any wiring report or error on the thermostat and/or the app?
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?
Were there any power outages recently?

Check for all the breaker switches to be on.
Turn the breaker switches off and then on again.
