Heatlink failed

jnvic — Sat, 09 Jul 2022 07:32:43 GMT

Hi,

Installed a Nest Heatlink 18 months ago and has stopped working. No lights on unit and on further investigation it looks like the 12v circuit is defective. I'm looking to replace it but have lost confidence in this product and don't want the same issue again after such a short amount of time. Can anybody tell me, does this sound like a common issue with this unit and have Nest addressed this with later models?

Thanks for letting us know ,@jnvic

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 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?
