One of the most common errors that you might encounter when you try to use Google's services is Google e77 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 e77 typically indicates that the Y1 wire is not detected by the Google system. A heat pump requires a Y1 wire. So, this code indicates that there is a problem with the Y1 wire. The fix is to connect the Y1 wire.
Make sure that the power to the unit is turned on. Make sure that the system is properly connected to the power source. If you have an on-line system, make sure that it is working properly. If you are replacing a Y1 wire, make sure that the new wire is identical to the old wire. If you are replacing a switch, make sure that the new switch is identical to the old switch.
If all of these checks are satisfactory, it may be that the new Y1 wire is not getting detected by the system. Each wire has ⅜ inch (6mm) of exposed wire. You may need to bend it over the mounting bracket. If this does not work, then you may need to install a new wire connector or ask a technician to do this for you.
Lastly, another solution you can try is to contact the Customer Service to solve this error. 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.
