Humming inside the TT
Not that it bothers me or keeps me awake, but what is that humming sound inside the RV when the shore electricity is plugged in?

- Is it the same song over and over?
- The transformers in converters can have an AC hum. The plates can vibrate from the magnetism generated by the wire coil. It sounds like the humming that comes from florescent lights.

Roll the dice. It might stop, or slow down, or ...
My wfco fan seemed to operate more or less randomly. I was glad the day I unplugged the whole converter.
Lol, that sure added to my lack of confidence to every electrical and electronic thingy inside the RV.RTCastillo wrote:

Probably the cooling fan in the converter that charges the battery and provides 12V.

Thanks, that makes sense. I appreciate your answer.- Probably the cooling fan in the converter that charges the battery and provides 12V. Many are controlled by a thermostat thus the fan doesn't run when the batteries are charged and there is little 12V use.
