E28-mains voltage measurement is uncalibrated; E12- temp. circuit calibration out of range. Check your service manual and go to service menu and try to calibrate first the humidifier and check your power PCB B/D, maybe just need recalibrations.

Micro-controller failure could be it?How to do the calibration?

You must have a service manual and follow the instructions for voltage calibration check.
