OK - I put in new optics board 3-4 hours ago, and 5 mins later, had the 2 blink deal. I powered off fridge at that point, and waited 20 mins. Plugged back in and got same thing (2 blink, pause).
In answer to your questions -
I just verified 2 blinks pause with the left side switch up, and solid red with the left side switch down. I pulled power on the fridge, and it is in time out for 5 minutes right now, per your other check.
The ejector blades are not up and visible, they are down around the 5PM position, below the level of the holes where the ice comes out.
I am waiting a few to send back to you to let you know the 5 minute test outcome.
OK just put power back on it, and now when door is open, i have no blinking led, regardless of the left side switch status
