This one was extremely interesting. The slide in this 2018 Thor Fourwinds 24F wouldn’t move when the slide switch was pressed. The customer had recently removed a fuse for the Co2 detector because it went bad and was beeping (you shouldn’t do this, always replace your Co2 detector when they go out). Turns out that the controller switch 12V signal was coming from the LP Co2 detector power circuit. I know, wild right?! Check it out here in this guide. This can also walk you through the troubleshooting procedure of the switch circuit of a Schwintek slide system.
