I have been having an intermittent icemaker issue for a while and wanted to get some advice. The icemaker will stop ejecting ice and the tray is full of ice. I just unplug the icemaker and plug back in and the icemaker will work for a while, month's sometimes, then stop working again. The unplug/re-plug in works again for a while. Not sure what part could be the issue since it's intermittent. Any idea's?
