Several thermostats require batteries to run on, and it would not be wrong to say that most of the modern thermostats are turning to batteries to save the data like time, preferred temperature settings during the outages, or sometimes to provide the backup to thermostat if you are running the rest of your HVAC system on some UPS or Generator. These batteries are depletable and can be used out sometimes. However, if your thermostat is not turning on after you have replaced batteries, here are a few things you need to check.
How To Fix Changed The Batteries In Thermostat And It Won’t Turn On?
1. Check Compatibility
The first thing that you need to be careful about is the compatibility of the batteries you are using. There are different factors involved like discharge rates, ampere ratings, wattages, and storage capacity of the batteries. Needless to mention that all sizes are not the same either. So, you will need to ensure that the batteries you are using with your thermostat are compatible with the model. You can find this information in the owner manual, or on the website of your thermostat by entering the right model number. If you are unable to locate that information, you should contact the manufacturer and they will be able to confirm that for you.
2. Check Batteries
While you need to check on the compatibility, there are slight chances that your batteries might not be as new as you are thinking. These batteries have a specific shelf life and the timing they can hold the charge for. So, you need to ensure that you are picking the batteries that are not expired and are working. There are still chances that there might be some problems with the batteries and they might not be able to perform as you expect them to be. So, you can try changing them with an alternate pair and that will solve the problem for you most of the time.
3. Check Fitting
Now another thing that you might ignore is that you might have damaged or turned the terminals that are connected with the battery and that can cause you to have such issues with the batteries and your thermostat will not be turning on afterward. So, remove and install new batteries very carefully and mind all the terminals and plastic moldings so that you don’t have to face such issues later on.
4. Mind the Timing
You need to be careful but steady as well because most of the thermostats have a two-minute window for you to replace the batteries. If you are not replacing the batteries within 2 minutes, you will have to reset the thermostat and then it will work like before. So, check on this and that will help you make it work like before without having any sorts of issues.
5. Check the Wiring
Well, if you are changing the batteries because the thermostat wasn’t turning on before and you thought it might be the problem with your batteries, you should check on the wiring as well, because the batteries can be fried due to short circuit and even after installing a fresh pair, it will not be turning on until the main problem is fixed.
