Troubleshooting Lippert Power Jack Not Extending or Retracting But Motor Is Working
Question:
I have a 2016 Forest EVo with the Power Jacks and the back jack wont go up or down. I got under to look and the motor turns on but see nothing spinning. Is it the motor or something else?

There are a couple potential reasons why the back Lippert Power Jack # LC298707 on your trailer won't extend or retract even with the motor running. It's possible that it may have been over-extended or something internally has been stripped or bent. Try using the manual crank on the jack to see if it's able to operate in this manner.
If it still struggles with the manual crank then the jack will need to be replaced.
If the jack works manually then I recommend making sure your battery is fully charged. These systems require a decent amount of power to actually lift up a trailer and I have seen where a battery is charged enough to power on the system and get the motor humming but not enough to actually extend/retract under load. Also make sure your ground connection is securely attached to a clean, bare metal surface.
If you're still having trouble finding the cause of this issue please let me know and we can continue to troubleshoot.
