That's actually my model's serial number. My problem is that I am hearing occasional thunder-like rumblings, not humming sounds like posted in here. I would turn the back switch off, let it sit for awhile. Then my sound was only coming from the soundbar. After a few days I switch the subwoofer back on and that thunderous rumbling goes away, only to come back every so often. So for now I have unplugged it from my wall and let it sit for an hour. It seems to be OK for now. The plug is 2-pronged, so I don't need a cheater plug.
It's way past it's warranty period. My soundbar is connected below my TV which is up against a wall. Is there something I could try with the soundbar that may stop the subwoofer from rumbling?

Hello,
Welcome! The most common cause is a failure in the subwoofer's bass amplifier, usually capacitor or voltage regulator related. You might try seeing if any local service center would be willing to repair it.
