Georgetown levelling jacks that go down and don't retract can be caused by a short in the control cable to the hydraulic control unit. This happened twice to me. If you have a hydraulic motor that turns in only one direction then this is likely the problem. Worst of all, there's no way to retract the jacks, even manually, if this happens. The hydraulic control unit is locked in the "extend the jacks" mode and you can't retract them when this happens unless you drain the hydraulic fluid from the system.
The solution is to unplug the power line to the extend/retract solenoid. It's located on the left side of the unit (looking at the back end of the motor) and is the only device on that side with wires going to it. After it's unplugged, the jacks will retract normally because the "no power" position of the solenoid sets up the hydraulic control unit to retract the jacks. DO NOT PLUG IT BACK IN until you want to extend the jacks again. The automatic levelling system will not work because it can't raise and lower the jacks but you can level manually.
This solenoid is powered directly from the battery and will drain the battery if you leave the solenoid connected. It does NOT go through the battery disconnect switch and will drain the coach batteries even if you've disconnected them. When this happened to me, it was the second time the batteries had been left fully discharged for an extended period of time and both house batteries needed replacement.
Notify your dealer that the diode in the hydraulic jack control cable failed. They should contact FR to get the new replacement cable from Lippert that has additional protective circuitry that prevents this problem. If you're going to the Elkhart rally that starts next weekend, add it to your list of repairs. Mine was finally fixed last year after Lippert was able to develop a fix for the problem.
