One of the most common errors that you might encounter when you try to use Google's services is Google e79 error. This error occurs when you try to access your account information or when you try to log into your account on the internet. This error can be annoying and frustrating because you cannot access the services properly.
The problem can be caused by an issue with your device system. If the system is in trouble, then it is possible to stop sending power to the thermostat. Another possible reason is that you live at a very high or low temperature place so this code appears. To fix this error, you need to try a few solutions.
First of all, error code e79 typically indicates that there is no power detected in the C wire of the Nest Thermostat. If you are not sure that the C wire is connected to the power source, it may be worth your time to test this by switching on the power. After that, check the connector in your device with a multimeter and confirm that it is correctly connected. If it is, then you need to start troubleshooting other possibilities, such as the control wires or a problem with the switch.
Try unplugging and plugging in the device again. You can also reset the thermostat for a few seconds by holding the button down for several seconds. This may help you to figure out if there is a problem with the device itself or with its wiring.
Next, check the wiring of your thermostat and ensure that it is connected correctly. If you have tested it and it still does not work, then you need to contact the manufacturer of the device and request that they send you a new one.
Or, you can contact the Customer Service to solve this error without changing the device. You can try contacting them through their customer support number or their website. The customer support will usually ask you to send them the error code that is appearing on your screen. They will tell you what to do next for your problem and give another solution.
