Mains hum

Probably many community members are quite familiar to the mains hum. What effect does it have on you?

  • It's good and bad. I just heard a hum yesterday. It told me that power was getting to an AC powered motor and that the passive components ahead of it may need replacement. Turns out the motor brake was causing the issue (after the burnt out wires from the main were replacedimage). The humming let me know that the troubleshooting was paying off because at first plug in there was no hum through the coils.
