You said you "believe" the red connects to the white. I want to be certain as I do not want to damage any electrical circuits by making an incorrect connection. How confident are you in your belief?
Do you suggest that I clean the connector and put it back together for the blue and black wires or should I connect these with a jumper wire also?
Just finished the repair, using a connector to splice the red and white. I used a butt connector instead of solder to connect the connector to the white wire coming from the door (and wrapped it with electrical tape). There was no play in the two red wires that were connected to the remnants of the pin that broke off so I wrapped my connector wire around the pin and secured them with a small wire nut. Then I reassembled the molex with the blue and black wires (which unlike the white and red did not look corroded).
The ice maker and water controls are working fine. Since the problem was intermittent, it will take several days to determine whether the new connection is more stable.
Thanks for the advice. No need to respond. Just thought the feedback would be helpful.
