my ice maker has quit making ice and the ice in the bin has melted. I suspect it might be a thermistor but not sure. If the thermistor was bad would it explain the change in temp in the ice maker compartment? All other areas are working fine. is there a diagnostic I can run on the unit? Code? to verify if the thermistor in ice maker is working correctly? Also, i show there are 2 different thermistors in the part diagram , can you tell me the difference. Thanks for your help.
i have tried to reset the unit. Turning it off and back on. no luck.

This model with the ice maker in the upper left fresh food compartment actually has its own sealed system for the ice box compartment. You have a cooling issue with that compartment. it may be a defrost issue or a problem with your ice box fan, or worst case would be an evaporator issue. First see if icebox fan is running and inspect icebox evaporator coil for excessive frost. If fan is running and there s no excessive frost the you most likely have a sealed system issue, which is very labor intensive and difficult. There is a thermistor kit for the icebox (p# 5303918416) which may be your least likely issue, but still possible. If the fan is not running then you need to replace it (p#241870801).If the fan is running and the freezer evaporator is excessively frosted up then you need to replace the evaporator bi metal thermistor (p#241962601) and/ or defrost heater(p#241962501).If the fan is running and the evaporator has no frost pattern then you are dealing with a sealed system issue. There is an icebox evaporator kit (p#5303918441). I have attached a wiring diagram/tech sheet for you and it does have diagnostic procedures outlined for you.

Sam , thanks for the reply. Couple of follow up questions. Would the ice maker stop making ice if it was a cooling issue. I would think it would continue to produce ice and just melt? Mine is not even producing ice. Would a bad thermistor cause the unit to not produce ice and also shut off the fan i.e. the cooling of the compartment? is there a video available that shows how to run the diagnostic to narrow in on the problem?

Can i get a reply. thanks.

Yes, the ice maker would not produce or cycle if the unit is not getting proper temperatures. The ice maker has a sensing thermostat that will prevent the ice maker from harvesting if it is not satisfied and recognizes that the cubes are frozen.
