David,
You probably have an aux air compressor to compensate for leaks. And I’d lay a bet that it has a blown fuse or, worst case has given up the ghost trying to keep up with your air leak. So plan A would be to hunt for the fuse and if it’s blown be sure to replace it with the proper amperage one for your compressor (look on the compressor label). Then, if the new one blows or the compressor doesn’t come on, or comes on and never stops (until it blows the fuse again) then replacing the compressor would be a good thing. Then, in the middle of the night you’ll hear the compressor come on instead of your head hitting the headboard :-). And you can get your leak fixed when convenient.
