I had a simular problem with my leveling jacks. The problem turned out to be my battery. On your leveling jacks controller you will see the voltage that your battery is charged to. Do not believe this. In my situation my indicator was indicating 13.6 plus volts. However, it turned out that two of the cells were bad. This caused all sorts of wierd things to happen when I worked my leveling jacks, mainly they would not retract. I recommend getting a battery analyzer for about $30 plus dollars from amazon. Just a cheap one. They test the condition of the whole battery. An example the battery in my RV now is on its 3rd year. I tested it yesterday and it read 13.25 V but is only 81% effective. I will have to replace my battery out next year, but this is based on only using it boondocking for 2 days, once in the year to come. I hope this helped
