Entry door keeps trying to lock while driving

My entry door has started to make an intermittent really loud sound from the locking mechanism during driving as if it doesnít think the door is locked and keeps trying to lock it.
Some times is several rapid fire attempts to lock, other times itís one or two. It may be silent for several miles, then go back to trying to lock.

The door lock is working fine, and can be locked/unlocked by the switch on the dash as well as the keyless entry, itís just an issue while driving. Itís really loud and distracting and making my normally calm dog very nervous.

Iím thinking thereís a door lock sensor thatís going bad and wanted to see if any of you have experienced this and/or know how I can bypass the auto lock feature until I can get this fixed.
Thanks
Bill

Just a thought - you wouldn’t by chance be hearing the stairs trying to open and close would you?

If so, check the stair wiring or magnet location on the door.

When I had our Dutch Star my door did the same thing and it was some corrosion on the jam contacts.

On the hinge side of the door frame, there are some brass spring-loaded contacts, mine had some black on them that I cleaned off with a kitchen scrub pad. After I got them back to shiny brass, all clacking stopped.

Might be worth checking on yours.

Thanks for the responses.
I just scrubbed the 4 contacts on the door and the jamb to a shiny brass and will see how it goes on our next travel day (Saturday).

If that doesn't resolve the issue, remove the sensors and clean the contacts on them (wiring connections), the body of the sensor and the spots in the door and door frame where they're secured.

Also make sure they are all sticking out about the same and they are springy. There is probably a spec for how much they should stick out. Mine look to be a quarter of an inch or so.

I applied this to the contacts, and no more issues for almost 2 years now.

Hmmmm, no joy on todayís drive after cleaning the contacts, removing the sensor blocks to check the connections and adjusting the lowest sensor on the door jamb to be flush with the three above it.
90% of the time the door tries to lock occurs when hitting a bump or rough road. On smooth roads itís mostly quiet but does occasionally try to lock.
This issue first occurred when the door was left open on a rainy day, but disappeared when the door dried out. Now itís back.
Iíll have to recheck the sensors. I suppose it could also be a failing relay or a loose connection inside the door.

I had a similar issue a few years back in our 2016 Dutch Star. My door as well as my basement door locks did the same thing thing ( a rapid fire ) In my case it was the TRI Mark system, I had to disconnect the module that was inside my dash ( behind the Tach and Speedometer ) By luck I had a up coming Newmar appointment. If I recall correctly the Newmar Tech said it was a bad ground. Hope this helps.

Thanks. Iíll look for that module and reach out to Trimark. I donít know which of the four door contacts is tied to the door lock actuator or where the ground wire terminates, so I have some investigating to do. I was hoping there was a function to bypass the auto door lock feature because the lock is working fine except when Iím driving.

So I think itís the air cylinder activated lock towards the top of the door making all of the noise while driving. Would pulling the door lock fuse on the circuit board in the bay under the driverís seat be an acceptable temporary fix to disable this lock while driving?
Thanks

I haven’t found a solution yet. I cleaned, adjusted and lubricated the contacts, checked the wiring, checked the alignment of the four contacts, tried pulling the “door lock” fuse and removing power from the Trimark module, and the problem still exists.
It happens mostly when I hit bumps, and interestingly on non bumpy roads it’s more prevalent when the road curves to the right than the left. I also hear that high pitched beep from the Trimark module each time it happens.
That “air assist” lock is powered by an air line that goes through a 12 volt solenoid on the firewall in the generator compartment but I don’t know if that 12 volts is triggered by the contacts on the door or whether the air assist is simply triggered when the parking brake is released.
I’m going to put a call into PTL and Trimark to see if they can clarify and help troubleshoot. I sent an e-mail to Newmar last week but haven’t received a response.
