I have an eleven year old GE side-by-side freezer/fridge with original icemaker model WR30X0318 which leaks water into the ice bin that freezes and keeps the auger from rotating. I ordered parts to repair the ice bin, which fit perfectly. Additionally, I ordered a new icemaker assembly part #AP4345120 (GE part #WR30X10093) which appears to be a universal icemaker for several GE models. I installed this new icemaker, but when it calls for water, the fill cup cannot contain the water, even with reduced water pressure. The fill cup also is for a universal installation and it appears to be more shallow than the original and it has a huge hole drilled into the side opposite from where the water enters... the original fill cup has only a small cutout for the fill tube and no other holes in it. The original fill cup will not fit on the new icemaker. My entire freezer became a waterfall. I was able to find the original GE icemaker parts on your webite, but not the assembled icemaker. Any suggestions on the fill cup?
Thanks!

Thanks, Gene, for the reply. I worked on this problem over the holiday weekend with no good results. The foil tape does help contain water in the fill cup, but something just is not right with the GE universal icemaker... when it calls for water to fill the tray, water runs out of the tray and into the freezer. I thought water was only spilling from the fill cup. I triple checked that the icemaker was level. I reinstalled the original icemaker and it holds water just fine. The problem with the original icemaker is that water drips into the ice bin, which creates a huge frozen glacier around the auger. Could the problem with the original icemaker be that the mold/heater has a hot spot in one area? I get ice from the icemaker, but it's always watery on the surface when it's ejected from the tray. I really would like to send back the GE replacement icemaker for a refund because I have mopped out my freezer three times this past weekend.
