As you can imagine, I've had these speakers for over 30 years. The woofer is now making a humm and the only thing I can do is unplug it (the satellites are working fine). I don't know where to go to get it repaired, or if I can do it myself...I'm not a wirehead.

Probably not. The red light indicate idle mode. The woofer might have an auto-sense switch. When activated the subwoofer turns on when an audio signal is sensed at the subwoofer input. Such switches often have three positions: Idle (Somewhat off, but not quite) Auto (Turns on the woofer when audio signal is detected) Allways on. (The woofer is allways on - you might hear humm in the woofer when no audio signal is present)
Fault is either from the main system or the sub-woofer itself.
You need to test both unit in order to detect which of the two is giving the fault, so that you can concentrate on the faulty unit.
Test the woofer with a AA battery or any other battery. Put your ears close to the woofer and observe if you will hear any sound. If the woofer makes sound, then it means the woofer is working, but if it doesn't make sound, then it means the woofer is defective. Or you can disconnect one of the working speakers and connect the woofer to that part. If there is no sound, then obviously, the woofer is defective.
If the woofer seem to be working, then the unit needs to be tested also.
Connect one of the working speakers to the sub-woofer's section of the main unit. If the speaker doesn't bring out sound, check the system's menu settings, check the volume and make sure the sub-woofer volume is raised to the highest level and not on mute. ( Note that most Theater systems has separate volumes for each speakers). If the volume is raised to the highest level and there is still not sound from the woofer part, then it means the woofer channel has burnt. It could be a fuse or a defective channel. At this point, I think you need help from a repairman.
This can be due to either the integrated power supply system or the amplifier itself. As a tecnician I can imagine the possible faulty components and I guess that the cost isn't too big. But since I don't know your area I suggest to ask from a technician at your area to check the subwoofer.

The humming could be a couple things.. First try a different outlet in a different room..Make sure the RCA is firmly in place if using LFE and none of the speaker wires strands are touching if using Hi-Lvl input. Also if using Hi-Lvl you might be getting feed back from the Amp.
sub woofers are very powerful bass , with incredible sounding technology. your problem might be with the woofer wall around the circle. open the box and take the woofer out.Check if there is any tare over the corners of the cloth. sometimes there might be a crazy noise because of a little opening in the cloth caused by small tare.. if so better change it with a new 1 and make sure that the new cloth has guaranty
damaged sub woofer eg.
Thanks for rating
your sub woofer has only one input to make it work. plug in your rca cables into the back of the sub woofer and the other end into the audio out or subwoofer out put on the back of your surround system.
also has 2 speaker inputs so you can expand your speaker setup. plug thos in and you can hook up 2 speakers to th output on the back of the sub.
im not sure about reconing,most expiriences ive had turned out not to good however partsexpressusa has replacement speakers and i think they also have recone kits as well. if i may make a suggestion dayton audio makes a really good sub if your in the market for a replacement.-z
In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs. Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.
