390QS Buzzing Sound
Several times last night we were awoken by a brief intermittent buzzing sound. Lasted approx 3-4 seconds.
It was in the rear bedroom area. Rear AC was off and no appliances running other than fridge and main living area AC.
We returned from an outing at 230pm and from the main area of the coach we could hear it again in the rear. Before we could get back there in an attempt to isolate it, it was over.
We're stumped! Any ideas???
