Only one car does it. So I don’t think I describe it very well. So if elevator 3 is at 3rd floor and I hit down call. The call will latch but the elevator will not open the doors. However if the elevator goes to another floor it will then come back to take the hall call.

Now separately elevator 3 and 4 both have the output board. I swapped them and it went away for a few days but it’s back now. But on elevator 4 the output light stays on until the call is answered but elevator 3 output light just flashes on then goes off.

To make this even better it’s the miprom is an overlay combined with a Dover relay logic. This is on a dc traction elevator
