Last week ice maker stopped making ice. I discovered the optics board was blinking twice, a pause then repeat no matter if the flapper was closed or open. So I replaced the emitter and receiver boards and now get a solid red when the flapper is closed. I removed the ice maker, removed some ice chunks and reattached it. I then turned the power back on and a few seconds later heard the water fill and about 90 minutes later heard ice fall into the bin and water fill again. Then nothing, it refuses to harvest anymore ice with ice seen in the tray. I re pulled the I/M, emptied and jumped the V and H. I watched the tines go around and assumed that part is fine and reattached. It then immediately filled and dumped ice about 90 minutes later, but then once again stops making ice after that point. Could it be the ice maker even though it does cycle once?

Thanks for any help, Steve
