This makes sense. I was all excitted to use the 'ice maker diagnosis flow chart' on page 2-3 of the manual and I couldn't get the ice maker to even harvest. I tried pulling the tines forward and advancing the gear with a screw driver, no harvest. I had a heck of a time getting the ice maker out because the gummy stuff stuck to the bottom. Once removed I checked for voltage at the wire harness and did get 120v across some pins. I have know idea what pins power what, but the ice maker was getting power somewhere. Looking at the wire diagram on page 5-4 it looks to me like it could be the ice maker control (but possibly not, because i was getting power) or what you mentioned with the limit switch inside the module. I'm leaning toward your diagnosis and am going to price a new ice maker for the customer. thanks.
