The elevator. Westinghouse MPH 2 with DCB solid state door board operator.

The problem. Doors start to close and mid run, from a few inches closed, to fully closed, they reopen, 4 or 5 times, without any input from the Cedes edge (which is new), door open button, car call or hall button. Eventually they close and the car runs fine!

This will happen at any of the 4 floors with the car on automatic operation. Have yet to have it happen on service operation.

Things we did.
New Cedes edge.
Had both RMH & MHC boards checked and repaired by World Electronics. Also swapped them with car #2.
Swapped DCB door operator board with car #2 and...... sent to World to have it checked out.
Replaced all 3 FCB boards in COP with new World boards. The LEDS on these make it easy to see if edge is broken or door open button pushed. They also show when doors are closing, opening and on the limits.
The only thing we see is the door close LED drops out and the door open LED lights up.
Ran new wires from FCB board to door operator board.
Used a spare traveler wire and swapped it with all other wires one at a time.
Also had World Freedom tool hooked up and when this happens, it does not show on any of the inputs that the door should reopen.
Also, the safety chain is not opening to cause this. Wish it was that easy.

Thanks for taking the time to read this and we'll take any help at all. We've worked on many, many MPH's and this is a first.
