Our 2017 Ventana 3709 bedroom slideout will not retract. It moves in about 2" then sound like the motor is under too much strain to continue. If you press extend, it moves back out 2".

Help!!!

two things come to mind, okay 3:

1) Call Newmar
2) Turn off the salesman switch (12V power) for a minute then turn it back on. Alternatively you can find the bedroom slide controller in the bay forward of the pegboard (typically) and unplug the connectors, wait a few, plug them back in.
3) Empty everything from under the bed, I think right side (on mine) is where the motor is accessed below the bed floor board and make sure nothing is blocking the function of the slide motor.
 
Neal about covered it.
 
Keep us posted!!

Try assisting it in mechanically (manually) to get past the point where its binding. It may run in on its own after that point. I can also see Neil’s point about something under the bed blocking the mechanism and you’ll have to expose it to move it manually anyway. I had one with a broken gear tooth and it wouldn’t make it past that spot without manual assistance. But your problem sounds more like binding or a weak motor or possibly a bad controller.

If your door side slide controllers are the same model and are next to each other, you can rule out the controller by unplugging both and plugging the bedroom controller plugs into the forward slide controller to see if it will bring the bedroom slide in. The door side slides on a 3709 are similar in size so they probably ise the same controller. I had a bad controller on my 2016 and Newmar replaced it with an “upgraded” model (Klauber KMG 1209).

These are my door-side controllers, both the same model and right next to each other so you can see that plugging the bedroom slide plugs into the forward controller for testing would be simple. They are both LMC30 Revision B controllers, likely the same as yours.

There were a lot of controller problems for 2016-2018. The 2016 and 17 problems were often solved by simply adjusting the amperage on the controller upwards. The replacement for my bad controller was a KMG 1209 - completely different unit but the plugs were identical so replacement was easy.

Thank you all for your quick response to my bedroom slide problem. I went on Newgle and found instructions to a few things to check as well as what to do to manually to bring in the slide.

I opted to unplug the 12V black and red wire connector from the controller. I was going to try and apply a 12V battery to the leads on the connector as suggested but I just plugged the connector back in, tried it and the slide came back in.

As Rich suggested, I will investigate the motor to be sure there's nothing impeding its operation and, I will find and replace the old controller with the newer one.

Again, thank you all for your help.

Is this a good slide controller replacement?

oks like it has the same female plugs.
 
I'd monitor it. Electronics do not like to be on for years as our motorhome's run electronics. A power cycle may have fixed it.
 
I agree with Niel - now that its working again it may continue to work for years. And also I agree that it would be smart to inspect the mechanism, check the mounting bolts, and verify the manual-retract method. It wouldn’t hurt to have a spare controller though. I think the cost for the replacement controller was around $100 from Newmar but that was a couple years ago. Probably 50% more now.

Personally I wouldn’t experiment with other third party controllers such as the Intellitec unit from Integrity RV parts without some reliable reviews unless its also the one Newmar is currently using. That said, it may be a better unit but some research would be in order.

Here are a couple of the Intellitec units “Integrity” sells for $187 on ebay for $60 less and free shipping:
And this is the unit on the Intellitec website:
The KMG controller that Newmar sold me as a replacement for the failing LMC unit is from the same company (Klauber Machine and Gear) that makes the slide drive unit (gear motor).

Edit: Newmar now sells the KMG controller I bought for $99 in 2021 for $215. Everyone is on the inflation bandwagon these days…:mad:. A little research also found that Newmar used to use the Intellitec unit and they have discontinued that practice using the LMC controller for a few years and now the KMG unit. I also found in a brief search that people had issues with the Intellitec units 8-10 years ago.

Great information from the RV Forum as usual.

Thank you!

Greetings--

This morning our bedroom slide would not come in. The motor works and moves about an inch in and stops then iIcan move it back out. I removed the two-wire connector from the controller and plugged it back in after only a few seconds but no banana, Then I unplugged the multi-connector for a few seconds and plugged it back but still no dice. Then I unplugged both for a few seconds and plugged both back but again the same. So I unplugged both connectors then came in, removed all our stuff under the bed and removed bed storage base and could see the motor and shaft. All looked okay without any obstruction. There are two wire nuts I checked which were secure. About ten minutes had passed so I went out and reconnected both to controller, pressed IN and the slide came in as usual.

The time before I recall I waited about ten minutes before reconnecting both. Maybe that's why it worked. As Rich mentioned, Newmar had issues with the controllers they installed from '16 to '18. I'll check eBay for the Intellitec controller Rich posted. Thank you all for your help.

Today we're headed to a National Forest campground called Prospector near Dillon, CO right on Dillon Reservoir. Water available only. We've decided to leave bedroom slide in until I get a replacement controller.

I would buy the KMG 0159 controller, not the Intellitec, as they discontinued the Intellitec years ago for LMC30, and then discontinued the LMC30 (aka C-Storm controller), and now use the KMG 0159. So the KMG 0159 controller is the most recent one Newmar uses as far as I know.

If the controllers are mounted next to each other on your coach as they are on mine, it would be an easy and useful diognistic test to swap them next time this happens and see if the slide goes in normally.

I posted the links to the Intellitec controllers to show that you can get them for $60 less than “Integrity RV” was charging, and the Intellitec may work just fine for you, but there were problems with it and Newmar discontinued using it, hence my vote for the KMG controller.
 
I could not locate the KMG 0159 controller but did find this one:

I found this from Newmar regarding replacing the old slide controller with the KMG APN 0159.

Not sure why I cannot get search result on Newmar's Catalog Shop search.
I found it in the Newpar catalog for $215 - but it’s a clumsy, primitive catalog so it takes some looking. I tried posting a link but it takes you to a generic page. Try searching on “PSO Motor Control” under your year and model. This is what you’ll find:

The problem with the one on Ebay is that it might be an 11 amp or 15 amp version. The one they sold me has the 21/35 sticker on it denoting 21-35amps as does the one I noted above. The one on Ebay might be any of the three - might be fine and it might not.
 
I just asked the seller if his is the 21-35 amp. It seems strange that there would be different amp ratings for these with the same model number.

Thank you for your help. Obviously, I'd rather pay his price than Newmar's.
