In the world of smart home devices, it seems like there is a new and exciting innovation almost every single day. The whole purpose of this is to make our lives easier and more free-flowing.
In the modern world, we are all pretty busy these days, so having little daily tasks and creature comforts automated for us is an attractive prospect.
In addition to that, we can now rely on our smart home systems to take care of our security needs and even clean for us. It really is the stuff of the future, when you think about it.
One of the seemingly millions of devices out there that were designed for this great goal is the Nest Thermostat. The whole concept of the device is relatively simple, on the face of it.
The idea is that you can remotely control the temperature of your home remotely. So, on cold days, you can preheat the house from your office. It also functions like a basic thermostat, for added practicality.
Naturally, though all of this may sound like it is pretty simple to run, it is actually a really advanced device. So, when things go wrong, it can be tough to figure out what is going on.
To that end, we have decided to put together this little guide to help you get everything up and running again. So, if this is the information you have been looking for, you have come to the right place.
Nest No Power To RH Wire
With smart home devices becoming more and more intricate at a rapid rate, users are bound to have added difficulty in keeping up with how to run them.
In most cases, it isn’t necessarily that the product is sub-par in any way, it’s just that there are so many things that you need to do to maintain the service.
Of all of the issues that users of the Nest Thermostat have been facing, one seems to crop up with alarming regularity – so much so that we needed to investigate.
Luckily, the news isn’t all bad. For most of you, you will be able to fix this error from the comfort of your own home, without a specialist.
So, if you are getting the error code “E74”, wherein the Nest has no power to the RH wire, just follow the tips below and you should be good to go within a few minutes.
As far as explaining what exactly causes the issue, such a task would prove impossible. In most cases, the issue occurs dues to a combination of reasons. So, instead, let’s just get right into it.
1. Furnace May Be Overloaded
Though we did state that it can be hard to figure out exactly why this error code is popping up, there is one thing that seems to be to blame more often than most.
In most cases, this will be the simple fact that there may be some interference to the power supply. Essentially, something is most likely happening that causes the power to your thermostat to be cut entirely.
Even if this is only temporary, there can be detrimental effects. So, to fix this, the first thing you will need to do is to check on your panels and secure them, if necessary.
What you are effectively looking for is if there are any condensation overflow safeties which may have been breached. Such an event is quite common when your furnace is overloaded.
Admittedly, this doesn’t have much to do with the Nest itself, but the effects from it can have ramifications throughout the system.
2. Get in Touch with a Technician or Call Customer Support
If you have the know-how, you could also go and check your wiring to see if you notice anything that seems odd. However, we cannot recommend such an action if you are in any way novice in this field.
So, to avoid causing any damage or voiding your warranty, it is usually the best call to contact the experts instead.
When you are talking with them, let them know exactly what is happening and then they can fix it for you in no time at all.
Given the volume of calls related to this problem, they will know exactly what to do and how to do it. While you are on the line to them, you should also make sure to tell them that you have tried the above fix too.
Basically, any little piece of info that you can give them will speed up the process that little bit more.
Alternatively, it can also be a good call to get a technician to have a look at the situation. Though they won’t likely be all that experienced with this device, they will be able to assess whether the issue is electronical or not.
