3 Ways To Fix Nest Says It’s Heating But It’s Not

nest says it’s heating but it’s not

These days, there is a smart device for pretty much everything. If you want to switch lights on in a different room, you can do it.

Need to unlock your door for a friend while you’re at work, you can do that too. It really is amazing how far this tech has come in such a short time.

For us, Google Nest is one of those stand-out smart devices. It’s a really simple concept, but it makes life just that little bit sweeter.

Being able to warm your house up before you get home from work on a winter’s day is just an absolute luxury. As is being able to set regular schedules and automating it well in advance.

With these luxuries, though, it always seems like you don’t know what you’ve got until it’s gone.

The sheer disappointment of coming home to a cold house when it was supposed to be warm is just devastating – especially when you’ve used the Nest as it was intended to be used.

Well, you’re not alone in this. In recent times, it seems as though many of you are facing this same issue.

What makes it even more baffling is that the Nest will actually say it is heating and working normally. But it is painfully obvious that it is not!

Because there is a lot of confusion out there over this issue, we thought we’d put together this little guide to help you get everything working again. And here it is!

How To Fix Nest Says It’s Heating But It’s Not?

We’re now going to show you a few quick steps you can take to fix the problem from home potentially saving you both time and money.

If you have very little experience in troubleshooting devices such as this, don’t worry too much. We will guide you through the process as best we can.

We also won’t be asking you to take anything apart or to do anything that could damage your equipment. With that having been said, let’s get into it!

1. Nest Not Pulling Heat from Furnace

With these diagnostics guide, we generally go for the most common causes of the problem first. In most cases, this whole issue will be the result of Nest just not pulling heat from the furnace.

When this happens, the Nest will still show up numbers that will indicate that everything is working normally. To get to the bottom of this one, we will need to check that your wiring is in order.

Basically, this is more of a visual test than anything else. The first thing you need to check is that the heat wires connection to the terminal is nice and clean. Have a look and see whether there is a large build-up of dirt and grime.

The cleaner the terminal, the better the connection. While you are here, make sure that the wire itself isn’t frayed or damaged in any way. You will also need to check that the connection with the furnace is good.

If you’re in any doubt as to what you are looking at, the white wires are for heat and the red ones are for the purposes of power.

Naturally, if you are in any way uncomfortable doing this, you can just call in someone with a little more experience and confidence in what they’re doing.

2. Try Cleaning The Flame Sensor

Though often overlooked, the flame sensor is a crucial element of your heating system. The way in which it works isn’t all that different to any other sensor.

Like those, this one will simply need to be cleaned up every now and then to keep it in tip top shape. For quite a few of the people who have reported this exact problem, this fix turned out to be the key.

All you need to do is just thoroughly clean the flame sensor. While doing so, you will be able to get a closer look at what’s going on.

For example, if there’s something blocking the sensor, you’ll easily be able to see it and remove it. Even if it is just shrouded in dust, make sure to remove everything that is stuck to it.

As soon as this is all done, you can out it back together and see whether everything works again or not. If not, we’re afraid that there’s only one remaining option.

3. Get In Touch With Customer Support

At this point, any other fix that is available to you requires a certain level of expertise. So, rather than taking a risk, it is best to turn it over to the pros.

Get it touch with their customer support service and make sure to explain what you have already tried to fix the problem.

That way, they will be able to diagnose the problem with relative ease and advise you on the appropriate course of action.
