The motor runs both ways but nothing moves.I believe your slide gearbox just gave up. Have you tightened the gearbox bolts? I think it is recommended to do it yearly. Mine got checked every six months.
Empty under the bed, remove the 4 screws holding the floor panels in place under the bed. Then you will have to crawl in there with a flashlight. You should see a shaft going to the gearbox. Check the bolts on the gearbox. But, from what you have said, you may have to replace the gearbox. Good luck and let us know what you find.
There are slots in the bottom of the tubing. Guessing there is a gear that runs in the slots. Don't know yet if the gear is shot or just loose.
Going to look at that some more.
Something that surprised me is how cheaply the bedframe is made. Put together with staples. It is falling apart.
