Amazon.com has a 6ft Eopzol power cable for the nest thermostat.

You can learn how to charge the thermostat.Over the years, I have installed hundreds of Nest Thermostats in my home.They work great for most people.

There are a few issues that can cause the battery to get low and then you have to charge the thermostat.

We will teach you how to charge the thermostat, but if you need to add a common wire transformer to provide enough power, we have additional resources for you.We teach you how to figure that out.

The Nest Thermostat does not need to be charged if you check a few things before you charge it.The thermostat should charge from the power provided by your equipment.

I've known people who thought their nest was broken because their air conditioning system was accidentally turned off while they were cleaning or remodeling.

There is a light switch next to your heating, ventilating, and air conditioning system.It is on if you confirm it.

The power on the nest will usually charge itself.If the power goes off for a day or two, it can take several hours for the nest to come back on.Thousands of people have had this problem.To make sure the power is on, you should check your circuit breaker.If you don't know if the power is on to your system, you can always remove the front cover and confirm that the lights are on.The furnace won't have power if you hold down the cover kill switch.

If the power is off or the nest has been a box for a long time, give it a few hours to charge.

Take the thermostat off the wall and charge it if you can't diagnose what's going on with it.You can use this to charge the Nest battery and to help diagnose any issues you might have with your home's electronics.

If you want to charge the nest from the wall, you have to have a micro-usb cable, or you can get a cable and charger for your nest.

The charging port on the back of the Nest Thermostat can be plugged into if you remove the nest from the wall.

If you have checked to make sure your power is on at your system and you've charged the thermostat manually by plugging it in, you can now test it.

If you want to see what happens, put the thermostat back on the wall.A common wire transformer may be needed if your nest is reading low power or won't charge.

If your heating and cooling system doesn't put out enough power, a common wire transformer is used to provide power to the thermostat.

The video shows you how to add a wire.The other common wire installation resources have also been included.We recommend the Common Wire Transformer.

I don't recommend replacing the Nest battery until you confirm that it's the issue.It can happen that the Nest battery needs to be replaced.There is a guide on how to replace the Nest Thermostat Battery in this post.

It's important to understand why your thermostat won't charge after you've learned how to charge it.

1The most common issue is that the power is turned off at the switch on the heating, ventilating, and air conditioning unit.

2.There is a small 3AMP fuse inside your heating, ventilating, and air conditioning unit.You can buy replacements on Amazon.

3.The thermostat does not have enough power.You will need to add a transformer if this is the case.

4.The power to the thermostat is cut off when the air conditioning unit fails.If this is the case, you should fix your heating, ventilating, and air conditioning system.Changing your furnace filter is one of the easiest issues to fix.The furnace filters have high levels of filtration for airborne particles.

5.There is a chance that your nest thermostat battery is dead.In the post about the Nest battery, we have included a guide on how to fix the battery.
