Nest Heat Link - No Power

JPMNest — Mon, 06 Sep 2021 10:02:53 GMT

Hi, My Nest Heat link has stopped working - no lights. There is 240 volts to the heat link. I assume the unit is dead.

How do I get this fixed/replaced under warranty?

Thanks,

John

Hi there, thank you so much for reaching out. Can you tell me if any LED comes on after you press the button on the Heat Link for 30 seconds?

Hi andysedd,

I'll do my best to get this issue sorted. Can you please help me with some answers to these questions?

How long has your thermostat been installed for?
Did the issue happen during the installation?
Is there any error on the Nest thermostat display?
Have you had any power cuts recently?
Have you had any work done on your electrical or heating systems recently?
- If yes, was the power properly restored at the fuse board after work was done?
How many zones are present in the setup?

Regards,
Cristian

Thanks. I have now sorted this by calling the customer service team on 0808 169 2307.

They arranged for a replacement heat link to be sent which I installed this weekend. All now works fine and I am sending the faulty one back today on a pre-paid service.

I would suggest not to worry about requesting contact on here but instead calling the customer service number. They will take you through some basic fault finding but if it is genuinely faulty they will arrange for a prompt replacement without too much trouble.

Hi @Prisque and @Antnie77 .

If you have not already check any breakers or switches at the location, to make sure nothing has tripped. If it all looks good you can try and cut the power to the Heat Link for a few minutes, if you are comfortable in doing so, and after turn it back on. See if it has any reaction after you power cycle it when you press the button on it.

If it still has no reaction let us know here and make sure to also answer the questions my colleague posted above.

Hi,

I have the same problem too.

I have followed all the suggested advice above and in the troubleshooting guides ( have hold the button 10, 20, 30 seconds) and it's still dead with no LEDs on at all. My heat link is 2nd gen.

Did the issue happen during the installation?- No
Is there any error on the Nest thermostat display? -H71
Have you had any power cuts recently?- No
Have you had any work done on your electrical or heating systems recently? -No
If yes, was the power properly restored at the fuse board after work was done?-N/A
How many zones are present in the setup?- I'm not sure what this means, but I'll guess 1.

Since our boiler is less than 2 years old we called our installer them and they came and exchanged it..I did say there seemed to be a lot that had gone faulty and he said there had been a bad batch from 2 years ago and they were just starting to go wrong....Not sure how true that is but it does seem to match up with comments I've seen were installed about 2 years ago...Is this something Google knows but is keeping quiet about!
