Strange sound from my 24.1

[Selurgniman]

Alright, this one’s strange. On my drive yesterday a high pitch electronic sounding tone started sounding coming from under the microwave. I didn’t notice it until a bathroom break where I left the engine running but I know it’s never made this sound before.

I turned off house power and all AC breakers but it wasn’t until I turned off the engine that the sound went away. When I started the engine back up the sound immediately started again. I can’t think of anything on the chassis located that far from the cab that would be emitting a tone…

Any ideas?

Hydraulic jacks loose or a little down?

I done have any jacks of any kind, just the stabilizers in the back.

Same if they are loose you will hear a sound with engine on
