Ice maker stopped making ice and gave E5 error code. The ice maker was replaced, now it only makes a couple ice cubes a day. Still gives the E5 error code. What else do I need to look at prior to paying for a technician to work on it.

E5 = Bad ice maker thermistor. Ice storage temperature satisfied but ice mold in frozen state too long. Possible an ice mold thermistor issue.

The original ice maker part number was W10746960 but that has been upgraded to W11579560

You can do TEST 58 below check the thermistor.

Service Test - 58: Ice Maker Heater Activation and Thermistor
Press SW3 to activate the ice maker heater and to toggle between on and off.
NOTE: Digit 1 displays the state of the heater. Digit 2 displays the thermistor state.
Digit 1 (0 = ice maker heater off, 1 = ice maker heater on)
Digit 2 (0 = temperature warmer than harvest temperature, 1 = temperature cooler than harvest temperature, 2 = open, 3 = short)

Also make sure its 10 degrees F or lower at all times in the ice maker compartment or it will not make ice properly and give that error code E5.
