I replaced the icemaker with a complete new one and the water valve keep going off and on over and over, so I swithed out another new icemaker and its the same thing? So I put the old one back in and it does not turn the valve on and off constantely...

I replaced the board and its the same thing?
Now the old ice maker takes to long to cycle and ends up melting 75% of cube but works, just creats a big glob of ice cubes due to the ice being small and melted away...
