Default Post-repair compressor start-up

Greetings... looking to understand others' experience on this one point. After you have replaced blown out rear air springs with new ones and reconnected all the air lines, does the compressor restart on its own or is there some command/action you need to do to cause this? Background is that I lost an airbag (as in no longer on the truck)... the truck went instantly to the frame and the compressor has been turned off for about 10 days but driven very little. I presume the compressor entered some sort of self-protection mode when it couldn't see the height sensors show any progress after running for a while. Thanks for any help.

Well, I can say that you do have to "wake the compressor up". Apologies for not paying more attention but numerous things were reset and the compressor then lit and filled the springs.

I turned the key on. That's I I did after new bags were installed. I also did service that small air control box in the rear. But compressor came right on.

Check for voltage at the compressor connector. If it ran continuously for long enough (trying to fill a bad/missing air spring), it might have blown a fuse, or the compressor has gone bad.
