Google nest Thermostat no power detected m25

[Jaime84]

My google Nest is giving me a no power detected M25 code, I have attempted to run a power test (with the system off) and the issue persists. Also I have checked all connections, everything is installed appropriately.

Hey there Jaime84, 

Sorry to hear that you're getting this error message, I know it can be frustrating, but I'm happy to provide some clarity. 

M25 error occurs when Nest Thermostat detected that there's  power connector installation issues. Here's a link with the steps how to resolve this. Please follow the steps and let me know how it goes.

Best regards,
