Karen, give Loren a call in Bend. He can probably tell you what to do: 1-800-843-2967.
I doubt if it's solenoids, since it sounds like they've got 3 slides not working - front curb and street and generator - not likely 3 sets of solenoids go out at once. One of the bedroom slides is probably electric, but the other is hydraulic and it's working - so the pump must be okay. Must be a fuse related to the front end hydraulics. If the slide topper didn't retract initially because material jammed, that could have stressed the slideout and blown a fuse or breaker. I've had the topper on my driver's side front slide lose a bolt in the reel mechanism on the front end, so the material wouldn't roll up, hanging out and pinching the slideout, though it didn't blow a fuse or breaker. It's always a good idea to do a walkaround just before driving off.
Sounds like there are two problems to deal with - first fix the slideouts, but then figure out why the topper awning failed, cuz it'll do it again.
