Lower Jack error
 

Hi All,

I have a 2017 Keystone Laredo 335MK travel trailer with the Lippert Components TT Leveling System. I was auto-levelling my TT when everything stopped working and kept getting an "LF Jack" Error. It said to retract everything to clear the error. When I try to auto retract, all the lights flash and the panel turns off. I can retract them with the panel arrows one jack at a time or both fronts or both rears. But when one gets to fully retracted point, all the panel lights flash and it turns off. I did put everything down about 6 inches and tried to auto retract, but when I do all the lights on the panel flash and the unit powers off. I removed all power to the unit for about 30 minutes to try and clear the error, but it will not clear or should I replace it with a brand new one. Got some cool offer from trailer parts online.

What else could be the problem?

Wouldn't warranty cover it?

I had a similar error where the one jac kwouldnt retract. I puled the neg. lead off the battery for 5 minutes, hooked it back up and it worked fine for me. Ive made a point of making sure that my jacks are always cleaned after a trip, would be a real pain in the a** to hafta replace them, sure they aren't cheap!

Call the Lippert customer service...they are very good at trouble-shooting over the phone. If possible, have access to your trailer because they will want you to try various tests to narrow things down. I just went through this..."right rear jack" failure. the jack wouldn't move. Unplugged the power terminal at the jack, attached a 12v battery to the 2 leads and nothing happened...something went wrong in the motor. Had to replace the motor.

Don't now if you have solved your issue yet, but a low battery can be the source of all kinds of nuisance problems.

Yes it does. but I was worried about what was the reason for the problrm?

Yeah I know. I did try that but didnt work .

Not yet mate. Will do that thanks for the tips. cheers.

Cheers bro.

Another reason to just stick with crank down jacks.

Sounds like all the old gummers that want roll down windows and wife adjusted side mirror. 'Jes more lectrical crap to go wrong' lol
