ICE maker no working

Hello
The ice maker thermostat closes a +9 degrees . You say your freezer temperature is at +12 degrees. This could be a cooling issue problem. One you get the unit down to -5 degrees to +5 degrees see the steps below for ice maker diagnostics. Also go to page #37 in the technician diagnostic link below.

Step 1
Press the Rocker switch, Pin 2 and Pin 2a are connected. The ice maker is switched on. No part is working untill the thermostat reachs -9℃.
Step 2
Therostat connected the whole power circuit, motor is running and heater is switching on. 1st loop starts.
Step 3
During the 1st loop running, the ice level switch will be released once, but no effect on the power circuit. Motor is running and heater is on.
Step 4
When the notch of the ice cam run to the water valve switch, which means the ice cam switch is released, the water valve is switched on. Water comes into the ice maker. End of the 1st loop.
Step 5
Ice making progress. Every component of ice maker is at the same position as step 1, as soon as the thermostat reaschs -9℃, which means ice is ready, It can go forward.
Step 6
Beginning of 2nd loop. Motor is running, heater is switched on. When stripper runs into the ice position to take the ice out.
Step 7
Due to the thermostat is not over than 9℃, when the notch of ice cam runs to the water valve switch by the end of 2nd loop, the water vavle is not connected.
Step 8
Beginning of 3rd loop, motor is running, and heater is on, keeping heating the thermostat to reach 9℃.
Step 9
When thermostat is over than 9℃, the thermostat disconnected, but motor is keeping running till the notch of ice cam reaches the water valve switch.
Step 10
Same as step 4.
The new ice production cycle like following steps over and over again, untill the ice level switch detect that ice box if full of ice cubes.

When the ice box is full.
All components stay at the original position. No more working.
Self Diagnose mode
Switch off the freezer light and push the rocker switch to unstable position for more than 15seconds.
When the rocker switch is pressed position 1 will connect to 1a and position 2 will connect to position 2a. The Motor will drive the IM CAM turn CCW at about 0.33 RPM, the heater is switch on the same time. From original status the rocker switch should be pressed totally about 15 seconds. Then release the rocker switch, IM will go on to finished the self test.
Conditions for switching on the water valve to Ice maker
It must fulfill both following conditions, the valve can swith on and the water can enter the ice maker.
* Thermostat is open circuit
* Water valve microswitch is released
