Jenn Air Frig/freezer Black

Bought and replaced the dual water solenoid because the ice maker overflows when the water valve opens to fill the tray. The ice maker has a heater element on it and it works. I need some help on what to replace or adjust to prevent the water from overflowing. It runs down on my hard wood floors. If I am not mistaking Whirpool mfg the unit. The unit was made in 1996 and has worked flawless until last week.

Please send some help and ideas.

Thanks,

Mark Grimm
