Here’s how to fix your Vivint thermostat with easy solutions.
Chances are that you’ve inserted the batteries of your Vivint thermostat incorrectly.
That’s to say because when having the batteries improperly attached, your thermostat will stop working since the electricity withdrawal will become impossible.
Here’s how to reseat the batteries of your Vivint thermostat correctly:
- Take the front panel of your Vivint out, underneath the screen.
- Expose 4 of the battery units and eject them.
- Place the batteries into the compartment again, with the dot facing towards the left.
- Repeat with the other side of the compartment, with the battery’s dog facing right.
Note: Before hurrying to re-insert the batteries, keep them out for the last 60 seconds, in order for your thermostat to fully discharge.
If you haven’t cleaned your thermostat’s battery compartment in a while, there’s a chance that dirt is blocking one or more of your batteries from making contact.
In such a case, what you should do is appropriately clean the compartment.
Here’s how to clean your thermostat’s battery compartment:
- Take out the panel of the batteries underneath the screen of your thermostat.
- Grab a Q-tip and either drip it into vinegar or lemon juice.
- Using the Q-tip, collect any corrosion and dirt on the battery’s contact poles.
- Grab a dry napkin and dry up the compartment.
Note: Don’t insert the batteries while the compartment is still affected by the lemon juice or vinegar.
Insert the units once you’ve dried up the compartment and it is dry on touch.
There’s a high chance that you’re not using the correct batteries for your Vivint thermostat.
Although the batteries Vivint uses are standard, some models may have different battery specifications, rather than the 4 non-rechargeable AA alkaline batteries.
For this purpose, it’s recommended to have the instructions book of your thermostat and open the book at the required batteries page.
There, you can learn what batteries exactly your thermostat uses and have them replaced.
Tip: Ensure that the new batteries you’re inserting and the old ones look the same.
If your thermostat worked with the previous batteries, it should work with the new ones but of the same type.
If you’ve made sure that you’ve inserted the correct batteries into your Vivint thermostat, perhaps the units are faulty.
If that’s the case, our best suggestion is to insert new batteries into your Vivint device.
We assume that you’re already familiar with how to replace the batteries, so we won’t bother you with that additional information.
Simply make sure that you’re inserting them correctly as we’ve explained in the first solution.
Note: Don’t use any second-hand batteries or units you’ve already used with an alternative device that you know works.
Instead, grab a brand new packet of 4 AA batteries and put them into your thermostat.
There’s an easy way to perform a power reset on your thermostat as a final fix against any power issues and blunders.
That is to reset your entire HVAC system through the circuit breaker.
Here’s how to power reset your Vivint thermostat:
- Go over to your circuit breaker’s box.
- Locate the lever that has an “HVAC” or “A/C” above it.
- Pull the switch downwards.
- After 5 seconds, flip the switch back up again.
Note: Your thermostat will reboot after the following sequence. Determine if it will work after the power reset.
Not really. Factory reset could definitely help with issues that are software or firmware-related, but shouldn’t have anything to do with the power of the thermostat.
Moreover, if your thermostat doesn’t boot at all, you won’t be able to perform a factory reset.
If your thermostat boots, here’s how to perform a factory reset on it:
- From the home screen, press the SIDE button for 3 seconds.
- Hit the DOWN button to highlight the installer and then again, press the SIDE button.
- Next, highlight RESET and then hit the side button again.
- Finally, hit the RESET button again and wait.
Note: A restart will follow up on your thermostat after the factory reset is complete and once it is done, your device is going to be reset.
Thus, to fix a Vivint thermostat that won’t work after a battery change, perform a power cycle and reinsert the batteries correctly. Ensure that you’re using the correct batteries and replace them if needed.
If needed, reset your thermostat’s power from the HVAC switch in the circuit breaker.
Now that you know why the Vivint thermostat not working after the battery change, use our solutions to fix the problem. There’s a chance that your thermostat got faulty and needs replacing or repairing.
