I have a Goldflight job that intermittently causes random cars in the group to reopen its doors after responding to a call. For example: if the car arrives at the floor on a car or hall call it will open its doors normally, then when shutting the doors almost make it full close and then reopen. At the same time it reopens the hall call light energizes for a second, then goes out. It usually reopens 3 times then takes off. This will happen randomly to all the cars in the group on different floors. Has any one seen this before? It must be a group issue because it affects all the cars intermittently.
