Help: Intermittent slide & hydraulic jack deployment

It is the autoreset breaker for the hydraulic pump - the 50A from factory can get weak or overloaded and trip with use (as it heats up from the large current). Some have fixed the problem by replacing out the 50A with 80A.
It is located in the compartment with the buss bar. I do not know where this is in the cyclones.
Hope this helps.

I'd expect the pump would draw the most current while extending the gear, but maybe on yours it's when the pump reverses. Usually a new breaker corrects the problem.
Mechanical binds, low battery voltage and loose electrical connections can also cause higher amp draw, tripping the breaker.

That's the quick fix, not worry about. But curiosity is that could this be a tale tale sign of a bigger issue. So I don't like to avoid little things because they could bite you in the arse big time later. Much rather have everything fixed and working correctly as it should rather turning a blind eye to it.

I have since done quite a bit of waxing of the slide sides, and lubing of the seals. Slides are moving easier now, and I have not had a "hesitation" since. Seems the overload may be a little sensitive (barely sized?) and that making it all slide as easy as possible makes a difference. Food for thought.

I only have the issue when retracting the landing gear. Not when extending them or running the slides.

Possibly there is a loose connection or short in the system that activates when you push retract button. The pump reverses via signal from the "Trombetta" mounted beside the pump (here is an LCI link, and another link - these come from here). I would suggest checking this device when you retract and experience the autoreset breaker tripping - if it is hot when retracting and not when extending - you may have a failing Trombetta. Otherwise I can only think there may be a grounding issue when retracting that does not show up on extending or slide operations.
Hope this helps,

Ill check that next time I grab the trailer from storage. Hopefully in two weeks. The issue also seems to trip more often with a colder climate outside as well. I would only assume this is due to the oil being thicker when cold causing the pump to worker harder to flow the oil.

We have been having the same problem with our 2012 Cyclone 3010. It started on the landing gear first. Then it started happening on the slide outs too. It is steadily getting worse. I'll check and replace the breaker first. Has anyone found where the breaker is on the Cyclones? I'm sure I can find it. Just thought it would save some time looking for it.

The 12V breakers are on a buss bar near the battery.
More info and pics in the 12V Troubleshooting and Diagnostic Guide.

On my 2012 3950 the breaker was by the battery, their should be several breakers in a row. You can find out which one it is by operating the landing gear and listening to which breaker clicks when the issue is at hand, then as it cools you will here it click closed and the system will be operational. I called heartland they told me to replace it with a higher amp rated part.
The breaker in my Cyclone was a 30amp, I replaced it with a 50amp.

Thank-you for the replies. That's why I like this forum so well. Everyone is willing to help each other with problems and it usually gets worked out by discussions like this. I'm sure that I'll have no problem figuring it out now. Had a chance to look at it last night before reading the replies. I found the buss bar. Just wasn't sure how to find the right one. I'll go to the parts store and get a replacement for it. I was ready to take it to a dealer to get it repaired before tonight. Have a good weekend and a Happy Valentines Day everyone! Hope to get rid of this stinking cold weather. Reaaallllyyy getting tired of this snow and ice.
