Slides stalling/stopping

[BB_TX]

I would not worry too much about that wire to the pump. Mine is 6 ga which is rated for 65 amps. But that wire amp rating is based on no more than 3 wires in a raceway or cable for heat management. And that wire to the pump is not in a raceway or cable. It is a single wire in free air about 2’ long and only carries current for a short period of time, 1 minute or so each time. Check your wire size to see if it is 6 ga or larger.

My wiring is 4 gauge, about 2 feet. Check your wiring. See the chart below

Montana has used #4 copper stranded wire for those circuits for the last 5+ (or more) years. That gauge is adequate for 80 amp service.

Hi all. Just wanted to get back to you and let you know a 50 amp breaker was toast. Got it replaced and everything works like a charm. Thanks for everyone’s input. Much appreciated.

[Carl n Susan]

Thanks for letting us know the result.

Owners manual suggests being plugged in to electric when moving slides.

I’m replacing my 50 amp to an 80 amp today but I suspect I’ll need to replace the 30 amp as well. When my slides stop I always know when the CB resets when the fridge comes back on and beeps. Thing is the fridge is on the 30 amp circuit so the pump control circuit must also be wired to the 30 amp. When I disconnected the pump sure enough the solenoids in the control circuits clicked but of course the pump didn’t engage.

I would check the wiring very carefully. Typically the pump is wired to a dedicated breaker that affects nothing but the pump when it trips. But there have been some who reported that in some cases some of the breakers have been wired in series. Which is wrong.

[bigdawgfinley]

The pump is on a dedicated circuit and its own CB however the valve control circuitry is on the other CB. Came from the factory that way

[Sutty’s]

Great info. Thanks a ton!

[Bad Moon]

Somehow, it’s strangely reassuring to know that it’s not just those of us with the cheap-o cable-actuated slides who are having problems.

[Sutty’s]

Everyone.

Bringing this back up as our 2020 3121rl just started doing the same thing.

For the record the battery draw down excuse doesn't hold water.

I've got 600ah of lithiums feeding mine via 2 gauge cable so it's definitely NOT voltage drop.

The self resetting are <$10.00 but I thought this is one area where they wouldn't cheap out especially since it's a known problem.

Recommended 80A breaker will be at an Amazon locker tomorrow.

So anybody with a newer unit... Keystone still hasn't fixed a known shortcoming.

They keep installing the substandard breaker so you are distracted from other more important issues. They probably only spend a couple dollars, maybe less, on those 50 amp breakers, but would have to spend maybe $10 to $15 dollars on the correct breakers, so that cuts into their profit margin on each unit. Somewhere in the Lippert documentation that they say a minimum of 50 amp breaker is to be installed, even though in the parts list for installation, they show an 80 amp breaker and have also issued a tech bulletin that says the 80 amp breaker should be used in place of the 50 amp breaker. Our rig actually came with a 40 amp breaker that fed the hydraulic pump and inside panel, so early on we were having problems and as soon as Lippert issued the Lipsheet about installing the 80 amp breaker, I ordered the breaker and got it installed and we haven't had a problem with the stalling since.

Just be aware that you will need to enlarge the holes in the ring terminals of the cables so they will fit on the larger posts of the 80 amp breaker. This will not cause any issues having the slightly less material on the ring connectors.

I am pretty sure, but can't find it right now, that one of the 2021 promotional videos advertised that they are now using an 80 breaker (finally!!).

I'm glad. I admit to being more than a little incensed when these types of things are ignored.

I have a 2019 3121rl and it came with an 80amp breaker on the hyd sys. Also you need to lube the slide rails underneath, which most people don't. Once they get dry it adds a lot of friction.

Thank you.

One problem I see with mine that may contribute to the slow action is the cheap “poly tarp” material keystone puts on the bottom of the slide wears out and causes excess drag. Anyone have any ideas how to fix it?
