### ⭐⭐⭐⭐⭐ Rv slide out problem solved
*by R***E on June 5, 2023*

RV slide out would extend but not retract. Replacing the relay for the retraction circuit solved the problem. The RV repair shop would have chatged $250 to trace the problem and replace this relay. Next time your slide will go out but not in or in but not out, look at the controller board and find the input and output slide out relays. Swap them and if the slide out now retracts but no longer extends them the relay that works is good and the other one is bad. Buy two they are cheap. In the future you will have a spare.
