HWH Jacks

[mj25]

I'm trying to problem solve why the back two jacks will not go down. I am including a video of my control box. First the yellow and red lights go on when the front jacks go up and down. Then when we try to put down the back jacks there is definitely a different sound and the yellow light comes on but not the red light. In the manual it says it should be a fuse or a relay. In the video it looks like both lights come on in the back. Would this one fuse or relay be the reason both jacks in the rear won't go down. Thanks. I'm also adding a photo of my controls in the rv. This might help show what jacks I have. Any ideas or thoughts are appreciated.

Ok, I can't get the video to upload, but maybe my description helped describe the situation. Thanks.

Is it the high corner or side? Can you get that jack to extend if you manual level(vs autolevel)? If so it's likely a bad pressure switch located on the top of the jack.

The purpose of the pressure switch is to allow the controller to stop the last jack(s) for stabilizing with enough pressure to stabilize without lifting the coach.

To confirm you can disconnect the wire on the pressure switch and it should extend when you autolevel, but turn off autolevel before it fully extends since it won't stop on its own and could cause damage.

You can try hitting the pressure switch with a hammer which may or may not help.

Do you now the series # of your HWH system ?

You don't mention auto level functions so I'm assuming the system is a 310 and not a 325 .

Have you checked the system fluid level with all jacks retracted ?
Low fluid would account for the difference in sound .
Have you tried using the rear levelers first ?

It is not a system that has auto levelers. Here is a picture of the leveling system inside the Rv. Thanks.

Here is a picture of the lights that go on when you try to use rear jacks. When I use the front jacks the yellow and red lights all work. With back jacks only one light lights up.

With that control board and control panel series 325 no auto function , I made a mistake and should have asked about a different series ( 625)

Should I put this on a new thread??
HWH controller problem.
The fuse blow when raising the jacks. I had to move so jumped the fuses, got the jacks up but in the process some lovely gray smoke rolled out of the box.
The slides still operate but no jacks. The Box is AP32235. I have located a newer box #325XX (do not remember the last numbers. Can the newer box with valves be used. What are the potential issues or problem doing this.
