I suspect the wiring circuit board is to blame and am looking for help to confirm and determine what to do. Can I replace the wiring circuit board or do I need to purchase a full replacement?
Note: I have two furnaces in the house so I have two Nest’s that comes in handy as I troubleshoot. I noticed the Google logo on the screen and flashing green light. Once the logo disappeared I could not turn on the screen to see anything. I did all of the following and concluded the wiring circuit board must be the issue:
Did I miss anything? I’m hoping there’s an option to only replace the wiring baseplate. Thanks

Hello Jasoncpslo,
Thank you for taking the time to let us know about your inquiry. I understand the frustration you're experiencing with your Nest Thermostat and the heating issue. Based on your thorough troubleshooting, it does seem like the wiring circuit board could be the culprit. Your detailed steps to test and rule out various possibilities are commendable.
Considering the symptoms persist even when using a known-working Nest Thermostat, it strengthens the case for a potential issue with the wiring baseplate. Before making any decisions, there are a few additional steps you can take to further narrow down the problem:
Let us know how it goes.

Mark,
I finally got the chance to follow up with your recommendations and the Nest is still not working for cooling, heating, or fan testing. I pulled the baseplate off and removed and reinstalled all wiring. And by the way, the wiring was new about two years ago when we renovated. The Neat was working fine before and after the renovation.

Hi there,
I appreciate your diligence in troubleshooting the thermostat. Since you've already pulled off the baseplate and reinstalled the wiring, and considering that the wiring is relatively new, it's perplexing that the Nest is not functioning for cooling, heating, or fan testing.
To further assist you, could you provide additional details about any messages in the Equipment settings or specific behaviors you observe when attempting to try the steps? Does it have a C wire? Also, have you checked the power readouts in the Technical Info settings?
Keep me posted.
Thanks,
Mark
