You love your Vivint system and that’s awesome. Because a more safe, secure, and comfortable home is a thing that deserves to be called awesome.

We know, we know, while a Vivint system is awesome, especially the Vivint thermostat (which is what this post is about), we’re not going to tell you that everything related to Vivint thermostat is awesome.

The reason we’re not going to tell you that is because it’s true. Sure, a heating system in winter and cooling system in summer can make you feel like you’re in Heaven, it doesn’t mean everything related to Vivint thermostat is awesome.

Here is why. Vivint thermostats can be quite expensive. Paying a lot of money for something is not something that we can call awesome. Alright, on the serious note it can suck because sometimes it can malfunction.

In such a case, the panel will either not work properly or not work fine. It can work for a few minutes and then stop working, it may not provide good heating, it may not provide fine cooling, it may change the temperature by itself.

As you can see there are many reasons why a thermostat may not be awesome. Plus, these were not the only reasons, the list is actually longer.

Nonetheless, now let’s focus on the important stuff. We’re going to tell you the 6 main causes of why a Vivint thermostat may not work and their solutions.

So if you’re ready, let’s get to it.

Not Heating or Cooling problem

Follow these steps to solve this problem.

Step 1: Press and hold the left button on the panel for 6-10 seconds.

Step 2: By following the last step, the settings menu will display on your screen. Now you show tap on the option called user.

Step 3: Now use the up and down buttons to highlight the option called Testing and then tap on it. 

Step 4: Now use the up and down buttons to highlight the problem that you’re having. If you’re not getting enough heat, highlight the heat option, and do vice versa for cooling.

Step 5: Press the button on the right to select start.

Step 6: After you’ve selected the start option, here is what will happen. The Vivint thermostat will run a test to make sure the wires are active and the temperature is changing.

When the test is completed, it means the Vivint system has made sure that things are working the way you’ve set them to be. But, don’t just rely on the panel, see it for yourself if things are working the way you would like them to be.

When you’ve made sure that heating/cooling is working just fine, click the done button.

Step 7: If your thermostat is providing heating/cooling, then everything is just fine, if that’s not the case, then there is a good chance that something is wrong with your HVAC system, therefore you should contact the Vivint customer support.
