Ice maker now working.
On 8/4 you replied to me about the led not showing on my ice maker. I replaced the two modules and the correct led sequences showed. I initiated one cycle by a manual fill of the tray but after ejecting the ice the tray did not refill. I discovered that the inlet tube had an ice plug which I removed. All seems to be working correctly now. I do not know if the bad modules and the ice plug were somehow related, or if the plug developed on its own during the time the circuits were bad. I appreciate the good advice that you gave. Thank you.
