Nest Heatlink issue

[MikeDublin]

Hi. My nest thermostat/Heat link has suddenly stopped working. I have tried everything and no luck getting it back working. It appears that there is no power coming to the heat link. 
do I need a new heat link? Where can I get one and does Google supply? I am in Ireland.

9/10 you need a new H/L as a component fails inside. Ebay is your best bet, as Google do not sell them.

Hi, @MikeDublin!

Thank you so much for reaching out to the community. I apologize that the Heat Link isn't receiving power. I understand that the heating system relies on it to function. Let’s work together and find a solution!

To troubleshoot effectively, please answer the following questions: 

• What type of Nest thermostat do you have? 
• Did the problem happen during installation or after installation? Was the thermostat installed by a Nest Pro or by a regular installer?
• When was it installed?
• Have you recently had service or maintenance on your electrical, plumbing, or heating system? If yes, how long was the power off for? 
• Did you experience any power outages?

This information will help to determine the best next troubleshooting steps.

Thank you for your cooperation. I look forward to your response.

Best regards.
