Replaced water valve (video was huge help since new valve fitting had changed from the original valve fitting and it wasn't obvious without the video how to connect the ice maker fill line to the new valve). this job took 15 minutes as advertised.
Replaced ice maker assembly. this 15 minute job took 60 minutes to complete. new ice maker had power cord with a linear four conductor molex connector, but my application needed a six (2x3 array) conductor molex connector. took about 45 minutes to swap the old icemaker power cord (with the correct molex connector configuration) and put it on the new ice maker.
