My heat link is faulty where can I get one?

[RJWebster]

My Nest heat link is not working, There is power to it but it won’t work at all. I have tried all H71 suggestions but to no avail. The unit is not very old. Where can I get another heat link?

Thanks for letting us know, @RJWebster

Could you tell me please when did the situation start occurring first and when was the thermostat installed?

Also, please answer to the following questions:

Are there any lights on the Heat Link? Does the boiler activate when calling for heat by pressing the Heat Link's button to activate Manual Mode?
Are you seeing any wiring report or error on the thermostat and/or the app?
Have you had any recent power cuts in your area? If yes, has the power been restored?
Have you recently had service or maintenance on your electrical, plumbing, or heating system?
If yes, how long was the power off for? (Be specific.)
Could you tell us please if you've checked on the breaker switch and fuse box?
Any blown fuse in there? Have you tried to turn the breaker switch off and on again? Any difference?

• Yes I did all you suggested. The Heat Link  is faulty. Google will replace it at no charge. Thanks
