We found that the GE Monogram Under Counter Icemaker (Model ZDIS15CSSJ) in a home we purchased was not making ice. The unit powered on and circulated water, but ice was not appearing in the bin. I found that many of the wires on the grid cutter assembly had been broken. I ordered the replacement part and found a service manual on manualslib-dot-com. The part arrived in less than a week. With the instructions in the manual, I was able to replace the assembly in less than 10 minutes. It worked flawlessly. I expect that I would have paid nearly $1000 for the part and a service technician to do the repair, so I am glad that I simply ordered the part and did the work myself. I saved up to $600 in doing so.
