Acela (6-31714) (6-15532 Business Class Coach 4 Door: door will not open

@ToledoEd posted:

The doors on the coach (6-15532) stopped working...well one door opens sometimes and closes when it feels like. The other 3 stay closed. Sometimes the door that opens does not close on command.  As you see below I opened it up When I test the motors of the 3 doors that do not open, they run fine and the doors open and close. (I put leads from a 9v battery to the terminals on the motors). The door motor seized as soon as I apply power. However, when I remove the motor from the gear assembly and give it power it runs fine.  The vertical worm gear wobbles when I remove the guide(?) on the top.  I thought that was the problem. However, the vertical worm gear on the motor opposite does the same yet it works fine and opens/closes its door.   I emailed Lionel explaining the problem and I did get a response.  "Hello  I want to point towards the breakout boards that connect to operating/LED lights   service"  I've asked 'Service'  to explain because I have no idea what that means.  I really appreciate that Service responded, but I'm clueless.  [I have noticed the lights in the passengers cars over so slightly flicker...not sure what that means...]  Any insights would be greatly appreciated.  Two questions"

1. Any idea how to remove the overhead baggage compartment?  I know I remove the 2 screws...but beyond that I'm unsure.  Do I muscle it out by spreading the sides of the car, which I am loath to do, or do I have to remover the motors on the end and slide it out?  I'll need to figure that out if I'm to get to the LEDs, I think.

2. Any advice as to how to remove the motor assemblies?

Thanks.

the motor/door gear assembly...I thought the one I point too was the culprit because it wobbles when the guide is removed. It's not. The working gear assembly on the adjacent motor behaves the same...but works. I think the black 'board" under the blue pointer supplies power to the cabin LEDs. There's another one on the other side.

Another look. The two screws annotated.

Well, for anyone interested, I did fix the door not opening problem...sort of .  I had to take the door motor assembly apart ( that was a 3 hr. learning experience) and discovered the drive gears were jammed or rather the assembly ( the big black chunk of plastic with a screw on top) that attaches the door to the drive gear (long worm gear that runs the length of the motor housing) would not move. I also discovered it was loose compared to it's counterpart on the opposite door. Once I firmly secured that part, the motor ran fine and the door opened and closed.  No problem. (The wobbly gear I mentioned earlier was not an issue)  So, I closed it up, put it on the track in the consist and the left had door that I 'fixed' opened fine but a left hand door on the other end of the car would not open!  Both doors on the right side opened. However, the blinking ground lights returned as soon as I started the door sequence.  After a few tries of resetting the train, the doors would close, but not consistently and only after a long pause after the doors on the two other cars closed.  I've not given up. My next steps are to open it up, determine whether it's another "mechanical" issue with door that will not move and I will replace the motor control board and light control board.  If that does not fully fix the problems...I'm done. Oh, the 4 door business car that's been the issue is first in line after the powered engine.   

I love this hobby!
