I have a GE PFSS6PKWASS Bottom Mount Refrigerator. Last week the ice maker failed and I got an intermittent "Lc Er" error. I dug around a little on the internet and suspected that I needed to replace the main circuit board, which I did. Even w the new board the ice maker doesn't function. A little more digging and I found via the self-diagnostic (press the ENERGY SAVER and ALARM/ LIGHT) that there is an ice maker sensor error. I verified that the wire harness is firmly installed to connector CN90. Does anyone have experience with this? Should I try to replace the ice maker sensor or are there other ideas?
