The Vivint thermostat is an awesome tool. It’s actually one of the best thermostat in the market. The heating and cooling capacity of the Vivint thermostat is quite awesome.
But there is one problem. If you’re reading this post, then you’ve got that problem. Sometimes the Vivint thermostat just doesn’t turn on.
If this is the case with you, then you have our sympathy. Because if such an amazing thermostat can’t even provide heating/cooling, then it’s quite useless.
But you do not have to worry because we’re going to help you solve this problem in this post. Now, there are many causes that could be the reason for this problem. We’re going to cover each of them, and then we’re going to solve them.
So now if we have your undivided attention, let’s talk about all the potential causes and their solution.
Vivint thermostat not turning on: possible causes and solutions to try
Here are the four main reasons. Dirt in thermostat, Blown fuse or Tripped breaker, Low, Damaged, or Expired batteries, Loose wire or terminal screws.
Now that we’ve mentioned all the reasons, it’s time to write an in-depth talk about them and provide the solution so you can use your thermostat and live a comfortable life.
Ok, maybe your life won’t suddenly become comfortable because of the thermostat, but it will definitely increase the comfort because temperature affects our comfort levels.
We’ve written these long paragraphs just to make you realize how important it is what we’re going to talk about next, because whether your life becomes miserable or comfortable depends on it. Alright, again maybe it doesn’t completely depend on it, but then again it definitely has some impact.
One by one, check for each of them. Of course, you can solve all the problems at once and make sure that the thermostat will work once the work is done.
We highly recommend against it for obvious reasons. Even if the cause you fixed at last will solve your problem, you won’t save much time and energy. On the other hand, if you fix just one or two causes at once, then check whether the thermostat works here is what will happen. The chances are pretty good that you’ll save a ton of time and energy.
As you can see, the risk is much higher than the reward with the first approach, so it’s better if you stick with the second.
Dirt in thermostat
You’re probably wondering, what can cause this problem and why is this important. If I have to tell you why it’s important, then you haven’t been paying attention to what I’ve read above (because of cooling and heating).
Now, as for what can cause this problem, that’s a good question, and that is something we can help you with. The main reason why this might happen is because you’re not a clean person.
Of course, you may be a clean person when it comes to your physical hygiene, but you don’t have a habit of cleaning the tools you won. Ok, you’re not to be totally blamed for this, because you might not know that you need to open your thermostat and clean it from inside every few months, at the very least.
On the side note, if you did know it but still didn’t clean it, then it’s your fault. We don’t want to point any fingers, but it’s true. Anyway, let’s move forward.
So here is what you’ve got to do now. First of all, open the thermostat. Gently lift it up from the mount, grab a screwdriver (Philip’s screwdrivers works the best), and start screwing.
First unscrew the upper ones, then unscrew the bottom screws. It’s important that you unscrew the screws in the exact order.
After you’re done screwing things up, it’s time to clean up the mess that you’ve created (on purpose or ok maybe by mistake). So grab a bottle of glint, a piece of cloth, and start cleaning the areas that are dirty.
If the dirt is in the place where you can’t reach with the cloth. Use a smaller object to reach that area and clean it properly. Also, be sure to do the cleaning gently, otherwise you risk damaging the thermostat.
Blown fuse or Tripped breaker
So first here is what you’ve got to do. After you’ve opened the thermostat, check for the blown fuse and a tripped breaker. If you’ve found a blown fuse or breaker that is tripped, change the fuse with a new one and as for the breaker just flip it a few times and it’ll probably start working.
Low, damaged, or expired batteries
Another thing to look for is the batteries. Check if the batteries are too low or are damaged/expired. Even if one out of four batteries is damaged or expired, you should replace it with a new one because all four batteries are required for the thermostat to work properly.
On the other hand, if only one of the four batteries is low, then charge it, but know that it won’t solve your problem. Because one low battery can’t possibly stop the thermostat from turning on. At least 3 out of 4 batteries are supposed to be low to stop the thermostat from turning on.
Loose wire or terminal screws
The last thing you can do is look for the loose wiring or terminal screws. If either of these things is loose, it’s enough to stop the thermostat from turning on.
If you’ve fixed both of them and the thermostat is still not working, see if the wiring of the thermostat is corroded. If that is the case, you should replace the thermostat because your thermostat won’t work any longer.
There are various reasons why your Vivint thermostat may not be turning on. We’ve explained all the major ones in this post. By applying these solutions, you’re guaranteed to find the answer.
If you still don’t find the answer, there are two things you can do. You can contact the Vivint support and ask them to send a guy and check the problem, or you can ask us in our comment section and maybe we can help.
We might know the solution to your problem for 2 reasons. Because you didn’t follow the steps properly, or our point for some reason didn’t click with you. In any of these two cases, we can help you out.
We’ve tried our best to explain all the solutions in a simple and easy-to-understand manner, and we’ve tried to cover all the causes and solutions. If you’ve found this post helpful, feel free to share it on social media so others can benefit from it as well.
