Humming sound in Seneca

We have a humming sound in the rear of our Seneca whenever we are on shore power. I'm not familiar with the components yet so wonder if the Seneca always converts 120VAC to 12VDC and that's where the noise is coming from?

Do others also have the constant humming? My concern is that the noise is a precursor to failure. It's also very annoying.

Thanks

Probably the transfer switch. Not a precursor to a failure, just the nature of the beast.

I have a 2014 Seneca 37TS and my converter makes a similar noise. I narrowed it down by shutting off its individual breaker and ...... silence! My transfer switch seems quiet since I still had the rest of the coach powered when I did the test. We have very large converters and I suspect larger may make them noisier.

When I have low coach batteries and high 12-volt load, it is slightly louder yet and the fans also kick in and out, adding to the cacophony. I wish it was hidden since it is in the bedroom. But it hasn't kept me up!

Common noise for the battery charger/ 110 volt to 12 volt converter. There are also cooling fans and that does contribute to the noise.

rgolding, but humming all the time? I am plugged in, 12V switch off, and it's humming. I would think it would stop running sometime. Chassis batteries may have some load but they are not connected to the house batteries via charger/converter.

Still putting my money on the transfer switch. Had that with our 08 SENECA after they replaced it do to the recall.

Did you try shutting off the "converter" breaker while plugged in to shore power to see if that made noise stop? That will take the converter offline but the transfer switch will be unaffected.

Doing that is the only thing that stops my Seneca's humming, my transfer switch is quiet. It gets louder as I add 12-volt loads. After running for a while with high loads the cooling fans eventually kick in.
