My problem started after i replaced my ice maker tray cause it was leaking. Now it wont fill up with water every time. If I jump T and H with a wire it goes through and fills it every time. I dont think it is even trying to fill with water sometimes. I try to be in the room to see if I can hear it but always miss it. When I do the T and H I hear the water run for about 6 secs and fill just fine. What part could be bad? Thanks for any help..
