I took a look at the manual for the trailer product.
the controls are likely the same.
There is no "Reset" function.
You really need to measure the voltage on the red wire going to the control panel. this is where the electronics senses the voltage level.
It sounds more like a poor connection. When the system is on, it draws very little current, so a poor connection will not show much voltage drop.
But when you try to level (run the motors), there is more current and the voltage will drop. Maybe manual mode bypasses the voltage check....not sure
If voltage is good, 11.5v or higher, then you controller is probably bad.
