No ice being dispensed

Icemaker works fine but will not dispense ice. Water is dispensed fine. When the lever for ice is pressed the lights on the fridge dim, the solenoid picks up and opens the flapper, and nothing else. Motor is good. Replaced control panel and the problem is the same. Could this be the mother board?

so you cant hear the auger motor running? A lot of times the auger motor will get frozen and not operate. but yes it is possible the mother board is blown I had one like yours once and wouldn’t dispense and when I removed the mutherboard it was blowed out for sure in fact it left an arc on the frig and back side of board was obvious where it blew out
