Odd noise when using propane appliances

[FindingMyPlace]

Does it make the noise on both tanks? If so I’d think it could be the regulator.

I haven’t tested this yet but will on my next trip.

Welcome to our owners technical forum.

My switch-over regulator hums too. The more propane flow, the louder it gets. Not ideal . . . but, it does not seem to affect the flow of propane are the ability to automatically switch tanks.

I have a 2019 303RLS. This is my 3rd rig, first GD, and I hear and odd noise that sounds like a high pitch hum when I turn on the cook top or the hot water heater with gas. it doesn’t make the noise when the refrigerator is running on Gas though. None of my other rigs did this so I can’t figure if this is a problem or just a nuance of the system. Thoughts?
