I have a Nest Learning Thermostat 3rd Generation bought and installed in April 2020 and working flawlessly since then. I haven't used my heating since around May. Today I noticed a message on the thermostat saying it "Failed to connect wirelessly to the Heat Link". When I checked the Heat Link it has no light, I tried pressing the button as recommended for 20 seconds but there is still no light. I tried power cycling it several times but there is still no light although it is receiving power, there is 240v at the N L terminals.
How and where do I go about obtaining a replacement.

Thanks for reaching out. I'll do my best to get this sorted for you as soon as possible.
Here are some helpful troubleshooting steps:
Press the button on the Heat Link and check if you have any lights on it
Check if the circuit breakers and the switches are set to on
Turn them off and then back on
Press on the button again and check for LEDs
Could you also 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 ( thermostats ) are present in the setup?
Regards,
Cristian
