So your Vivint thermostat is not turning on the AC, no worries because we’ve got your back. In this post, we’re going to help you solve this problem.

We’ve got plenty to cover, so let’s not waste any time chit-chatting and get straight to the business.

Vivint Thermostat Not Turning On AC

Dirt is stuck in the Vivint Thermostat

There are two possible reasons for this problem. Dirt is stuck in the thermostat and the Wire or Terminal screws are loose.

Before talking about how to solve these issues, first let’s discuss how to turn on AC on a Vivint thermostat.

How do you turn on the AC on a Vivint thermostat?

how to turn on vivint thermostat

The answer to this question is pretty simple. You don’t turn on the AC on a Vivint thermostat. Are you confused? If you are, don’t worry, cause we are going to simplify what we said above.

The reason you don’t turn on the AC on a Vivint thermostat is the thermostat turns the AC on for you. What we mean is a thermostat is a tool that has the capacity to produce air.

Whether we’re talking cool air or hot air, both types are produced by the thermostat.

Many people were asking this question, therefore we feel the need to address it. Now, with that out of the way, let’s move forward.

In the next section, we’re going to talk about whether a fault in the thermostat can cause the AC to stop working. After that, we’re going to talk about the possible reasons that could stop the thermostat from working properly and we’re going to talk about their solutions.

We’ve got plenty of stuff to cover right now, so let’s keep rolling.

Can a thermostat make your AC not work?

can a fault in the thermostat stop the AC

This is a good question, can a fault in the thermostat stop the AC from working properly or stop working at all? The answer to both of these questions is an astounding YES.

Can you guess the reason? We’re going to give you a little time for guessing. So go on and take a guess. If you’re done guessing, then read the next paragraph.

The reason is that the thermostat is the tool that is actually producing the air. So a fault in the thermostat can stop the AC from working properly or working at all.

There are plenty of things that can go wrong with the thermostat. Some of them may not cause any major issues in the time being, but if ignored for a long time, they do have the potential to cause big problems.

There are some problems that are going to become an issue immediately, in one way or other these problems will stop your air conditioner from working properly.

Now there are some problems that will not become the problem in the future. This is because they will become a problem that needs to be dealt with in the present. Also, they may be incredibly inconvenienced to deal with.

This is because they won’t just affect the performance of the air conditioning, but they will stop it from working entirely. Now everyone would agree that not getting air conditioning when you want it, can be incredibly inconvenient.

Alright, with all that said, now let’s talk about the possible problems with the thermostat that can stop the AC from working and the solution.

Vivint thermostat not turning on AC: Possible reasons and solutions

There are two main problems and we’re going to discuss them in this section. Both of these problems are related to the Vivint thermostat, and both of them can stop the AC from working.

First, we’re going to name both reasons, then we’re going to talk about their solutions. Here are the names.

  1. Dirt stuck in thermostat
  2. Wire or a terminal screw is loose

Dirt stuck in thermostat

If dirt is stuck in your thermostat, then your thermostat could stop working, therefore the AC won’t work. This is actually one of the most common problems that AC stops working.

There are two cures for this problem. One is the temporary cure and the other is the long-term cure. Which one would you like to know first?

We bet you would like to know the long-term cure first, so you can get rid of this problem once and for all.

So that is what we’re going to do. We’re going to talk about the long-term cure first, so you can get rid of this problem once and for all.

Are you excited? Of course, you are. So here we began. The solution to solve this problem once and for all, or maybe a better way to put it is to not experience this problem ever again, is to clean the thermostat once every 2 months.

The reason the dirt gets stuck in your thermostat is that you don’t clean it often enough.

The thermostat is required to be cleaned between 3-6 months.

We know you are thinking if the requirement to clean the thermostat is every 3 months, then why should I clean it every 2 months?

The answer is, that sometimes on very rare occasions, the dirt can get stuck even for 2 months.

So to be sure that you never experience this problem again, so stop being lazy and clean the thermostat every 2 months, it’s not much work to do.

Now we should talk about the short-term solution. The short-term solution involves cleaning the thermostat. We know, it turns out, that learning the short-term solution is necessary for making the long-term solution work.

We never said it wasn’t, so you can’t blame us. Now, let’s talk about the short-term solution. Let’s talk about how you can clean the thermostat.

Here is what you’ve got to do first, grab a Phillips screwdriver, other screwdrivers get the job done, but Phillip’s screwdriver works the best.

Now, it’s time to take the thermostat off the mount. To do so, gently grab it with the tips of your finger. It’s very important to be gentle because not doing so can damage the mount.

Push it backward and lift it upwards until the thermostat comes off the mount. Once the thermostat is off the mount, put it down and turn its face backward.

Now pick up the screwdriver and first open the two upper screws and after that, open both bottom screws. Once the screws are open, grab a piece of paper or cloth and a bottle of glint, and start cleaning the thermostat.

Clean all the areas that have dirt stuck properly. This should solve your problem unless this was not the problem. So let’s discuss the second potential problem.

The wire or terminal screw is loose

Either one of these two things can stop the AC from working. Therefore, check for both of them, and even if one is loose, fix it and your problem should be solved.

If the screw is damaged, which is never the case, here is what you’ve got to do, replace it with a new one. On the other hand, if the wiring of the thermostat is damaged, you should replace it with a new one.

But, in case the wire is not just damaged, but it’s corroded, it means that you’ll have to change the thermostat.

Conclusion

You’ve learned both about the possible reasons that could stop the AC from working, and you’ve learned the solution for both problems.

We’ve tried our best to explain everything clearly, still if anything is unclear let us know in the comment section and we would love to help.
