H72 error - Heat link no lights

Dibaxus

Hi,

My nest show H72 err, the heat link is dead - no lights. I read all the topics regarding this issue, try to reset the power, press the button for 30 secconds - nothing works. I have 230V on the input of the heat link so is not an electrical problem. I don’t have a cut in power before the err pop up. I use 9 nest in my house for in floor heatings, all the other are working fine. This one is dead, if I press the button the actuator doesn’t engage. I live in Romania.

 

Thanks for the help!

Thanks for letting us know, @Dibaxus

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

The thermostat was installed in summer 2021 and the problem occurred three days ago.

Thanks!

Found it. Thank you. Now we'll need to authenticate your account. Please navigate to https://goo.gle/2zjncoz and sign in with the email address linked to the Nest account before clicking "Yes". Let us know when it's done please.

Thanks for that. From what we've checked in the system, the serial number you've provided us in the form belongs to a thermostat sold in 2019 and expired in Dec 2021. The warranty period expired in December 2021. In order to be able to consult with our senior support team about this, I'll need a proof of purchase from the thermostat. A receipt or anything on paper or online. Please attach a picture of it here.

The A/C guy that ripped out my old unit, inside and out, he did everything including installing my thermostat.  But I had to set up my WiFi to interact with my Android plus set it up also, so that I can work it when I'm away from home.

I really don't have any proof of purchase... There is any chance to check in the system the activation date? Maybe you can help me to solve this.

Thank you. We'll check on the thermostat and we'll be right back with you. The activation date was on 14 August 2019. Where did you purchase the thermostat from?

I'll work on writing a lot less. I didn't know there was only 15 minutes. I do talk a lot. Have a nice day.

You're right, I made a confusion with another thermostat - this one is likely to be installed in 2019.

No worries. We'll need a proof of purchase to escalate the case to our senior support team in order to be able to request a replacement for it. Even though I'm not sure it will be granted being out of warranty, but it's worth a shot. Otherwise, we're not gonna be able to help with replacement. Please let us know when you've found it.

Since I haven't heard from you in a while, I'll have to close this thread. Should anything else come up, please open another thread and we'll take it from there. Have a good one and stay safe!

Have you looked under your phone app.  You should at the least, be able to manually turn the heat and or A/C manually. On mine, once I open the app, I go in and make sure that it's on A/C... I can't do heat at all, I live in Florida.  I probably won't be of much help for you..... reason being is that I've only had this unit since the end of June, therefore, I haven't even tried to turn on the heat.  Maybe I should try.  At least incase my heat has a similar issue,. I won't be needing it as of yet.  I'll pray that you come across someone soon that can help you through resolving your heat very soon.  It's hard to believe that it's cold where you are at.   Hopefully you are not in Alaska.   Sorry I couldn't be of any help.   Just in case, have you tried restarting your nest thermostat?  Wow, I'll be needing your help if I ever have to juggle 9 items from Nest. Take care 🙏🏼
