Suburban Bedroom Heater Making Wa-Wa Noise

I don't know anything about my 2004 Itasca Horizon 40AD bedroom heater, because it has always worked like it should.

I don't what size it is, but it may not matter.

This suburban bedroom heater starts fine and sounds fine, but after it heats up for about 10 minutes it starts making a "Wa-Wa" sound or has a hi-pitch and then a low-pitch.

Might this just be the sqwirl cage heating up and because it's dirty it is spinning out of balance? (Just a guess.) Does anyone know for sure, because this Wa-Wa symptom happened to you too?

BTW, I can just put up with the sound, because it's not that loud, but when things like this are "signaling" COME TAKE A CLOSER LOOK, I have learned to not ignore these warning signs.
