Trailer hydraulic motor will not come on to raise the trailer. It will lower it - had master certified RV service technician out to look at it - he troubleshooted for almost 2 hours and came to final conclusion that it must be the motor. The solenoid can be heard to make a noise when the button is pressed to raise but the motor will not raise up. You can crank it up and then the motor will lower it, but for whatever reason the motor is not kicking in to raise it. Battery is good - switch is good - wiring conections are good - transmission fluid level is ok - he added just a little but it is within one inch of top appropriately. Any ideas?

It's been up in my backyard since I brought it home and this is first time to lower it for travel. At first it wouldn't go down -- didn't seem like the safety bar would release - pushed the up switch to make sure it was up high enough to release - and it went up a little and then stopped and wouldn't do anything - either up or down.

When technician got there they checked a few things and then raised it up by hand so the safety bar would release -- thought that fixed it because it then lowered fine -- but it would not raise up with the switch - the motor just wouldn't kick in - so they checked switches, wiring, everything they knew to check and concluded that it must be the motor. Any ideas where to get a motor in Houston area or should I jsut call manufacturer and have one shipped?

Being so ignorant about electrical and hydraulic issues, I don't know what else to do but wait to see what the repair tech can come up with, we were supposed to take it out camping for first time this weekend, and would really appreciate knowing if anyone had other thoughts on what could be causing it to work on the lowering action but not the raising action.

I would double check the battery to make sure it is good before getting into messing with the motor. It may have some charge left in it but not enough to handle the load of the pump motor. If you can put jumper cables on and try raising it first that may tell you something. Motors just don't go bad from sitting but batteries can.

The service tech did plug in to 110AC to test to see if it just needed more electricity - would that be same as jumping the battery?

My hunch would be the battery. It is possibly showing a "surface charge" of 12v and not having enough "juice" to energize the hydraulic motor. Did the tech try jumping the solenoid?

I agree with Bob. Clean the battery terminals & try it. Have the battery checked & or jump it from a good battery. I would bet it is a battery.

It would have to be plugged in for a reasonable amount of time to get the battery up to enough charge to raise the top, assuming the battery is taking the charge. Been there, done that.

on mine the motor does not run on going down, my bet its the battery you need to charge it or jump it. the charger built in the camper is a trickle charger.

sounds like the battery to me..

Good info about the motor not running when lowering. I found that out from Monarch today when I called. The trailer had been plugged in for about ten days prior to this problem starting, so hard to believe it's the battery -- and all lights inside shining brightly - plus technician said battery is good. The service tech did try to jump from the battery to the solenoid (is that the property terminology?) He called Monarch today and they seem to think it is the motor. I sure wish I knew RV repair in Houston area who is really experienced with Hi-Lo. But, I should be more trusting that these guys know what they're doing I suppose.

mine wouldn't do anything but click either because it was not level.
i had it at an angle for runoff.
once i leveled it it went right up.
