Icemaker and Water Valve Control Diagnostics

The icemaker and water valve connects to the main board but the main board does not control ice
production or water valve operation. The consumer does have the ability to turn the icemaker off thru the
customer control. When the icemaker is turned off, the main board quits sending line power to pin 8 (black)
line wire. Pins 4-5 connect to board neutral and pins 6-3 connect thru the board from the icemaker to the
water valve to activate the water valve directly.
