Electric Beds Won't Work

That just happened to ours also. :(

I've had to replace two limit switches on mine. Easy job once diagnosed.

They run on battery power. Does the bed motor make a noise when she activates the switch? Blown fuse maybe?

If she can't find anything obvious, it may be worth having her call the selling dealer, or even take the unit back to the dealer for a checkup.

Limit switch. Blown fuse at the limit switch. Pins holding the beds up. If used - previous owner may have raised how high the bed can go and might have done something to the limit switch or broke it.

Will need to check to see if power is making it to the limit switch. If so is there an inline fuse at the switch. Is the limit switch broke.

Inside the bed rails (where the chain is located) there are limit switches (one at the top and one at the bottom). Make sure they are both working. Last year our lower swich got stuck closed which didnt allow the beds to lower. I found a replacement switch for $2-$5 from Radio Shack and it fixed the problem.

Did she pull the safety pins?

Few thoughts. Knowing if it's used/new (assumed used) brand/model of RV and what beds are installed can help.

20am, 30amp or 50amp won't matter as the power to the beds should be 12v. As donn0128 pointed out chances are its in the 12v system. Assuming RV is used and been sitting on a lot I'd agree the battery either needs to be charged or it's dead. The converter/charger could also be the issue, if you are plugged in you should have 12v to all the systems. Finally the beds could have issues themselves.

I suspect she either does not have a battery installed or it is dead. She needs to learn what a volt meter is and how to use it. A decent (inexpensive) volt meter is the number one most valuable tool needed for electrical trouble shooting. Without one you have no clue what to expect or where to start
