Retracting requires a valve to be opened to let the fluid return to the reservoir.
1. Open the front hood on your coach. The one on the outside of the coach.
2. Just inside the grill (if gas, behind the battery) are 4 valves. There is one for each jack. To manually open the valve and let the fluid return to the reservoir turn the "T" handle counterclockwise 1/2 turn until the fluid begins to flow.
3. Once fully retracted, ensure the "T" handle is turned clockwise the same number of turns.
4. This must be done for each jack.
Why the valve is not opening is another story. With an assistant in the driver's seat, listen for the "click" when the store button is pressed. If there is no "click" the problem is electrical and needs to be followed up with a meter to check where voltage is being lost.
I just helped a member this past week with a coach like yours. His jacks would not deploy. Turned out to be corroded connections on the pump start solenoid.
