Lock out arm malfunction

I have a 2005 Newmar w/3 slides. The kitchen slide lock out arms do not always engage when the slide is moved in, however I have never had problems with the slide not operating. The slide is currently in, but when the button is pushed, you can hear the motor running for rear lock out arm but nothing happens. After the motor runs for abut 30 seconds it shuts off and nothing else happens. Anyone have any thoughts or know of an overide for these lock out arm switches? Thanks

Welcome Mike to the forum & irv2.
In this PDF in the end section you will find info on your lock units. They operate in conjunction with the control unit for slide.
When you read the spec you will find that poor voltage can cause problems, I would check plug connection and clean with some contact spray to clean them.
Not sure you can disengage the lock function from that control without causing other problems.
Most of the problems is from the locks getting wet when out from the weather.
People have cleaned after removing and have got them to work or just changed them outright.
Wire leads can also cause problems also and they have repaired them also.
There is more information in the Quick Tips link for your slides.

If you disconnect the molex connector from the slide controller you can use jumpers from 12 volts and ground and you can activate any of the two lockarms or the slide. + to + is one way and + to - is the other way. You need to be careful as you are defeating the safety switches (do not run the slide for instance if the lockarms are engaged). You can have one person connect the jumpers while another person is watching the lockarms to see what is going on. On one of my slides I had to adjust a "limit sensor" which is actually a stove bolt under the lockarms. This sensor is used to turn on the LEDs for locks on the controller such that the slide does not open when lockarms are engaged and locking...

Solution

Thanks to 007 & DBeauchamp.....I did find the PDF outlining slide and lock arm functions and we trouble shot from there. We determined that the the limit sensor bolt on that lock arm is not in contact with the proximity switch. It somehow got bent slightly and was not engaging that switch. Could also be why I have had problems in the past with the lock arms on this slide not always engaging. We are going to use your suggestion today and jumper the operation of this lock arm. Thanks

UUGGHH If you look at the rest of the pins, I think you will find them all bent. Check and see if you get a lock arm light. Prox switches do go bad under the "bent" 1/4 inch screw.
Take the leds loose from the prox switch at the controller and put a meter across the leads and have someone pass a screwdriver across it and see if it makes.

I can't find a number for the lock arm unit only the controller for lock arm unit in this link.
If its Intellect related you maybe able to change it.
Spec says with lock arm out contacts are not protected from weather as allot of people have found out.
