Ice Maker didn't produce ice cubes.

It was not complicated but it took more squeezing and reaching into the narrow space than actually removing three screws and unplugging the electrical harness. But that was all that was necessary, to install, three screws held the unit in place and re-connect the electrical harness. It saved me about $100 in labor and the inconvenience of scheduling a service call and waiting for a week or so. The best part was that I ordered the unit on line on Tuesday eveining and it was at my home by Friday afternoon with no extra shipping charges. Great service!.
