very strange, i was at the job to service today, this time i put the car on inspection at the top floor, anticipating having to press the door reset button after shutting the unit down to service. to my surprise, when i turned on the power and went to inspect car down, i decided to just turn on normal, and the doors operated fine. so i checked again, shut off power with out putting on inspect and sure enough had to press reset button to get doors to work. any way did not have time to deal with it today, it is only a 2 stop, and does not get used that much so maybe next month i will delve into the problem a little further. thanks for the info, i will look into it.
