My daughter has a Rockwood Roo hybrid that blows a 30 amp fuse whenever the slide out is closed all the way. I thought I had the problem solved by thoroughly lubricating the slide, but the problem has returned. Nothing seems to be binding, there are no wires being pinched--everything worked fine last year.When the slide is extended, we can hear a "clutch" of some sort making a nasty noise when it reaches the end of its travel. Upon retraction, there is no clutch noise; the fuse simply blows as soon as the gasket around the slide is compressed.We have found that by being very careful and stopping at exactly the right spot we can save ourselves from a fuse change but this feels more like a workaround than a solution. At the moment I'm thinking of changing the fuse size to 35 amps. This, combined with careful retraction, would probably go a long way towards correcting the situation. I'm sure no dealer would recommend this, but at this point I really don't know what else to do. Any suggestions?Thanks, Bob

There is an overload on the circuit when it approaches the closed position. It may be difficult to find but I would start with finding the point that the motor starts drawing higher amps. After that position is located, you can inspect and see if something is causing the motor to draw the extra amps. It may be a bad alignment, a loose rail, or some other mechanical binding.

the slide feeds from the battery somewhere, My fuse was a line fuse inside the battery box, I replaced it with a 30 amp ckt breaker like this, 30 amp breaker

electric slide motor ? Not hydraulicthere should either be a load sense circuit, like automatic steps useor a position stop switchwhich ever design is being used, it is now malfunctioningget out the books and look it up and find the partif she doesn't have the books, get the slide model info and look online for the service infoin the meantime, maybe replace the fuse with an auto reset DC breaker, in place of the fuse, the right size, no need to go over size and damage the motorit will trip when you get the slide all the way in and motor load goes up, then reset in a few minutesso the slide will go out next timeBUT find that book and the problembefore the motor is damaged and there are (2) problems

If the fuse is just in-line near the battery... I also would be tempted to go 35 or 40 amp.If the fuse is on a control board then I would be looking closer at the motor if it could be worn out or have an internal short.

This means when the slide out reaches full extension or retraction, the motor clutch causes that ratcheting sound and you release the button(prevents blowing the fuse). IF the Motor ratchets on extension then does NOT on retraction your motor/Clutch is defective. But not worth replacing.
Mine has made the ratchet sound only during extension. Motor stalls at the retraction limit. Has done this since new.

Had assumed this was normal... now I am not sure. No matter, as we never open a fuse.

Some Electric slide motors have a clutch feature. This means when the slide out reaches full extension or retraction, the motor clutch causes that racheting sound and you release the button(prevents blowing the fuse). IF the Motor rachets on extension then does NOT on retraction your motor/Clutch is defective. But not worth replacing. Install a 30 amp Auto reset 12 volt breaker. That way, the breaker resets after a few seconds. Jayco actually installs Auto reset breakers for some of the slide rooms because of this. The basic rule of thumb is, you NEVER should adjust or move the Force adjustment on a slide room control box if you have this type. That is why most of these type boxes have a paper seal over the adjustment pot. The Intellitec(Newmar uses these) brand slide controllers are the exception to this. Doug

Like Wiz says, we just hold the switch until it stops.

There's a click under the floor near the slide motor when it stops. The specs of the Klauber motor in mine show there's no auto-reset built-in to the motor. So I think there has to be a separate auto-reset breaker hidden in the the floor somewhere. But I've had no luck finding it. Nor have I seen any micro-switch arrangement.

I measured the slide current (8' wide, ram style): ~5A normally but got up to ~20A just before stopping. Or thereabouts.

Anyway, good luck!

Where is your load sensing board for the slide located?

which ever design is being used, it is now malfunctioning
get out the books and look it up and find the part
if she doesn't have the books, get the slide model info and look online for the service info

in the meantime, maybe replace the fuse with an auto reset DC breaker, in place of the fuse, the right size, no need to go over size and damage the motor
it will trip when you get the slide all the way in and motor load goes up, then reset in a few minutes
so the slide will go out next time
BUT find that book and the problem
before the motor is damaged and there are (2) problems

My 2000 southwind has no load sense, just a in and out switch.

I found a book, I know what the load board looks like and how to adjust it, I can find it nowhere, mine was also blowing a fuse when closing, the 30amp breaker box fixed it, the in/out button at the door is the only control I see, it will continue to try and move when closed if I push that button. I've looked all over for a load control board.

Should at least be diagnosed. If the numbers check out OK that takes you down one path. Excessive amperage will lead you down quite a different way.

Do not increase the fuse side. Find the problem and fix it. I would consider a 30 or 25 amp circuit breaker.

is yours electric motor driven slide or hydraulic ( BIG DIFFERENCE )

if its electric motor driven, what stops it from blowing the fuse, if you hold the switch after the slide is retracted, most people do't let go of the switch until after the slide stops moving
there has to be something that 'stops the motor' and its not the switch your pushing on
