We have a Schindler MPh II that has been having intermittent problems for a month now after a lightening strike. We have changed all boards and software but the problem remains. I can not chalk up to heat which I was trying to do when it ran a week during mild weather but in last couple of days it has went down serveal all times a day.
So what happens very intermittently is the computer appears to lock up with no faults. The doors stay open for no specific amount of time, somewhere from 30 secs to 5 mins, then will close, starter will kick on, up to speed contact comes on, but an output from microprocessor don't turn on to let it leave so the starter kicks on, then off, then door opens and it sits there again...with no faults, no block sensor edge, no stuck button, no stuck door open...but a direction to go up and keeps latched call.
Any help is appreciated. I'm thinking of requesting new software.
