The icemaker on this unit should not have any blue wires. There is a blue and a pink wire going to the defrost heater, though. Maybe it came loose.
Your condensate drain is frozen up as well. Remove the back panel inside the freezer to expose the coils and thaw out the drain trough. You can use steam or very hot water to speed this up. A quick check of the defrost heater and thermostat with your OHM meter will confirm their situation.
If you get time, please post all the letters in your model number so we can help you if needed.
