Seneca 37HJ Under Bed Fuse Box Buzz

[Martigg]

In our Seneca 37HJ there is an annoying buzz coming from the fuse box which is located under the king size bed. Has anyone else heard this buzz and if so been able to eliminate it?

It is probably your converter's transformer. If it doesn't buzz when you're not on shore power, that'd be my guess. If it's the same noise level as mine, I'd recommend just flipping on a small table fan; you'll completely forget about it.

My guess it is actually coming from the Transfer switch, ours hums a little as does our Progressive EMS unit because of the contacts in them. Sometimes the contacts can get dirty causing them to be louder.

As Rustynuts has said, it's the transfer switch. The only way to 100% eliminate the buzz is replace the switch with one that uses DC holding coils.
