Humming sound

RoDa

Is it normal for there to be a humming sound inside trailer when it is plugged into shore power?

If you are hearing a fan noise, it is coming from your converter. That is the black box down near the floor on the driver's side of the trailer.  When the converter charges the battery, the fan is designed to keep the converter cool.

If it's a electrical buzzing or humming noise, it could be the converter or it could be your EMS/surge protector, if you have one.
