You have 120 Vac at PCB

However, on further inspection the connector for the water valve, at the cabinet, looks abnormal, its not seated properly.

Damaged / Bent Pins

It may be necessary to use an inspection mirror or your phone to see at the angles some of these connectors are located.

After the pin was bent back into original position, and the connector inserted properly, the valves started working as designed.

This unit was turning awkwardly, and sometimes the complaint will be the icemaker rotates all the time, this will most always be a wiring or connector issue.

The harness connector looks good.

If the pins on the PCB however are bent, If they can’t be straightened, replace the PCB.

Another connector issue to be aware of is if someone

has tried to trouble shoot the unit and put a meter probe in the wrong end of the connector and damaged the wire. 

(This is wrong! Go from the other end with needle leads). 

Now the pin on the PCB either won’t connect or be intermittent.

This is repairable. You will need a fresh undamaged wire and splice it into the harness as shown, you will need to submit a ticket to TCC and request the wire kit.
