Nest 3rd Gen heat link is dead

Community Member

Hey all,

My Nest heat link has died. Power to the unit. Struggling to find my proof of purchase but it’s around 2 years old.
Anyone else been through this and could tell me what my options are? Do customer support read the posts here?

Same here, Heat link died after two years. No solution yet

What’s worse is that I’m an electrician and have been recommending them and installing them ever since!!! This is going to bite me if there is no resolution for customers

Thanks for letting us know 

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

Also, please answer 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 message 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?
