Lippert slide issue

You have the LCI Schwintek slide mechanism. Your diagnostics and thinking are wrong. The slide controller IS telling you what is wrong. It also tells you WHICH motor/wiring has the short, if you read the LED flashes per the diagnostics ON the controller. To isolate WHICH motor is Motor 1 or Motor 2---Put in override, disconnect the motor 1 plug at the controller and activate the slide. The MOTOR that then starts up is Motor 2. That means the other is Motor 1. What you have is a wiring fault from the controller to that motor. Depending on the OEM, the cable from the controller to each motor may be 1 continuous wire or 2 sets of wires. If 2 sets, the main wire goes from the controller to the area UNDER the slide room outside at the track mechanism and then a shorter 8 foot cable connects to the motor running up the inside. With just one cable it runs from the controller and then up the sidewall to the motor. It works in override because they motor has a red and black wire from the controller and the other wires are (motor revolution counter wires), that keep the room in time and synch when going in and out. The odds are the cable feed for that motor has come apart or is pinched. Doug

IF under warranty, don't MESS with it. Get it in for warranty repair. It takes me longer and at YOUR expense to repair what the customer screwed up attempting to do their own repair.
