RV AC
My Dometic AC seems to be cooling just fine but has started making a humming noise that seems to be louder inside than outside. Not sure what to check here?

More than likely the may be a loose support around the compressor on the roof. Might be inside section of the unit.
It only happens when the compressor kicks on. When it cuts off before the fan shuts off the humming stops.
