Error E159 message

[LaurelG]

We got this message and tried to take out the blue wire and reinstall it.  I can’t read the previous posts about how to fix this.

The E159 error means no power is detected on the C wire.

Was it working before?

Check that the wire is connected to the C terminal on the control board in the furnace/air handler.

Hello there,

I wanted to stop by and see how I could help.

Thanks for lending a hand, @Patrick_Caezza.

@LaurelG, could you also help us check your thermostat's power readouts on the Technical Info settings? Also, I found an article about the wiring report with troubleshooting steps. Let us know if you need more help.

Regards,
Mark
