I had a passenger side kitchen slide out motor replaced at Newmar. They told me the motor had a dead spot in the motor causing it to start and stop and get out of sync with second motor. Has anyone repaired a motor with this problem? I thought I read somewhere about taking motor apart and cleaning armature or contacts?

2018 DS 4369

I would say that with all of the parts, pieces, and such that I would not attempt to rebuild the slide out motor. Plus, parts may not be available. It seems that just about everything is use then throw away. You might want to keep the old motor (if Newmar will allow you to) and do an autopsy on it. Might be interesting....

I would take it apart and try to fix it. If you can't take the motor to a rewind shop and get a price. Even if no one will repair it save it. Most fail from a broken gear and yours should be good.

We are a 2018 DSDP 4369 (Spartan) with the EXACT same issue.. I am trying to figure out if we can either find the motor at less than $1400 price - or rebuild the motor. Did you ever figure this out - or, did you simply replace the motor at Newmar? Thanks!

Newmar uses several different motors and transmissions in their slides. This H350 is used in the double motor kitchen slide of the Dutch Stars. I've broken that motor twice. Both times, a tooth broke off of the main gear, causing a dead spot. The broken gear is hard to see unless you move the red grease out of the way.

The first motor was replaced under warranty. About a year later, the same one (front motor) broke again. The motor has a small round attachment on the end that syncs the two motors. I thought that the issue, so I called Klauber. I wasn't happy and let Klauber know that I wasn't happy with their product how much Newmar was marking up their motor, about $900.00. The tech was surprised. He put me on hold and spoke with an engineer. When he returned, he told me that the engineer thought it was probably a bad controller since the same motor broke twice. He said the motor was probably receiving more amperage than the rear, making it do all the work.

I ordered two new motors and the controller. I replaced both motors and kept the one good one as a spare. I installed the controller and then reset the limits. I would advise anyone who replaces one of these motors to reset the controller....it's very easy. I made sure the slide stopped at both the in and out position and wasn't pushed any further in or out than needed. The controller is screwed to the ceiling of the bay, about the center of the slide. It can be hard to find as they put it between two frame rails that are only about 6" apart. You have to be looking up to see it.

The FWS runs off of the HWH pump, so voltage isn't as critical, however the kitchen slide runs off of 12 volts. Consequently, I always have the engine running when I extend the kitchen slide. Knock on wood, good slide performance since I replaced the motor.

Lastly, I've become pretty quick at replacing these motors.

I found that the motor is fairly easy to remove, but much more difficult to reinstall and align the four bolts. The motor is mounted in a metal cage, just slightly bigger than the motor. It's easier to remove the cage or at least loosen it and then remove or reinstall the motor.

Hi Dutch Star Don - thank you so much for the detailed response. I do have a few quick follow up questions. I've received a $2,700 (7 hours $1,400 labor + $1,300 motor cost) quote to replace the motor / adjust slide - so trying to assess whether I can/should complete this (we lived full-time aboard our sailing catamaran for three years - did all my own repair/maintenance work). If you can please provide 1) the hi-level process you used to remove/replace the motor, 2) where I might find instructions on the 'reset' of the controller', and 3) where you actually ended up purchasing the motor - that would be hugely helpful as I contemplate taking this project on :-).. Thank you again!

I had one of the two kitchen slide motors replaced, ($1,4000) and sent out a post asking if anyone know's of a place that rebuilds them. The motor was making a popping noise.
I was contacted by a person that monitors this forum and has a machine shop. He asked that I send him my motor and he would look at it. Well, he sent me back pictures of a broken gear and then went through the pain staking process of fabricating a new gear.
I now have the motor back as a spare, but the money I compensated him for his efforts was no where near the amount of time he put into it.
I'm actually not sure if the motor I received back will work, but I carry it around just in case.
