Hello
See the ice maker diagnostics link below for your ice maker. I would go to the flow chart on page #4 and go through the flow chart diagnostics. This chart will take you step by step on each component testing and diagnostics.

The Twist-Tray Ice Maker (IM) is a 10 cube ice maker manufactured by Sankyo. It is a single unit with no replaceable parts. The IM operates with DC voltages of 14VDC and 5VDC, and water pressure between 30 and 120 psi. It produces around 3.5lbs of ice per day (4lbs per day if MAX ICE is enabled).
IM timing and logic is controlled by the UI Core Control Board. The IM has the following operational components (Figure 1):
• DC Motor with bi-directional movement
• Bail Arm to sense ice level in the ice bin
• Internal feedback switch to determine motor position
• Thermistor
The DC motor twists the ice tray. Ice is detached by the twisting motion, no heater is needed. The motor also operates the bail arm. The bail arm, and the internal feedback switch, checks if the ice bin is full.
The internal feedback switch helps determine if the ice bin is full and monitors motor shaft
position.
The thermistor senses the temperature of the ice tray to determine if the water is frozen.
(Below 8°F (-13°C) for Normal Ice, 5°F (-15°C) for Max Ice.
The IM has five standard states during normal operation. They are:
1. Homing
2. Filling
3. Freezing
4. Ice Ready
5. Harvesting
Other states include Homing Paused, Harvesting Paused, and IM Jammed.
Homing
When power is initially applied to the IM, it will enter the Homing state. 14VDC is applied to the motor driving it counterclockwise (CCW). The internal feedback switch closes when the ice tray reaches the home (fill) position.
If the IM is not in the Home position after 45 seconds, the IM will enter the Jammed state. The IM will attempt Homing every 60 minutes while in the Jammed state. Filling IM filling is skipped for the first cycle following a power interruption to the refrigerator. This ensures the IM is not overfilled, and results in a 3 hour wait for the first batch of ice to drop.For subsequent cycles, 115VAC is applied to the IM water valve solenoid for 15 seconds, filling the IM with 3.38 fl. Oz.(100ml) of water.The water fill tube has a heater to prevent icing of the fill tube following Filling. At the beginning of the Filling state, the filltube heater, if on, will be turned off. After filling completes, a 20 minute delay timer will begin. After these 20 minutes pass, the fill tube heater will turn on for 90 minutes, or until the beginning of the next fill cycle, whichever comes first. During periods where the IM is inactive (turned off, full ice bin, etc.) it is possible for the fill tube to freeze over. After the IM becomes active again, it may take one or two cycles to thaw the ice maker inlet tube line. Freezing After the 15 second fill time, the IM enters the Freezing state until the ice cubes are ready. The ice cubes are ready after time and temperature requirements are met. Time and temperature requirements vary between normal ice mode, and MAX ICE. In normal ice mode, the thermistor temperature must be at or below 8°F (-13°C). In addition, a minimum of 85 minutes must pass. If the RC or FC door is opened during the Freeze state, the timer is paused until the door is closed and additional time is added. For example, if the FC door is opened for 5 minutes, the timer stops for 5 minutes and 5 minutes are also added to the 85 minute timer for a total of 95 minutes.
In MAX ICE mode, the minimum timer is decreased to 70 minutes, but the thermistor temperature must be at or below 5°F
