Out of Stroke Error Code on Lippert Ground Control 3.0 Electric 5th Wheel RV Leveling System  

I'm getting the out of stroke code at the end of the leveling cycle when the system does the final grounding of the Rear jacks. The trailer is level but I have no way of dropping the center jacks. The jacks function properly on manual so, they're getting full power and have plenty of stroke left

I've gotten this error three times in the last two weeks with different extension numbers for each jack. I do not know what the actual "limit" should read when reached. I wish I did, then I would know which jack to put more levelers under. I don't believe it actually reached the limit though. Each time it they all read different stroke lengths in the manual menu. 1 - what is the stroke limit for both types of Jack's? 2 - I can't recall if I had already plugged in the 50 amp service. If the battery level is a question, or wiring to the battery then that's possible I guess. 3 - one of the times I took it to manual and extended them manually beyond what it called stroke limit because it didn't seem to be fully extended. 4 - also the manual that the trailer was delivered new with, does not describe the light indicators and what they mean....flashing etc. Really appreciate anyone's help. Many thanks

Continually/repeatedly get Out of Stroke error one one specific jack RF whenever the jack grounds, and actual comes under weight. The leg is not out of stroke this error occurs whether the jack has extended 2 or 6 or 10. Within less than 2 seconds of RF grounding and actually begins to lift weight, it stops with the Out of Stroke error.Have switched lift motors between RF and LF, the error continues on the RF. Have disassembled both legs no binding or issues with the legs. Have checked wiring and connections from battery to control module to jack motor for continuity and voltage. All check out fine.Is this a control board issue?
