This was not a straightforward repair - for that, it would have been easier. Did not use the wiring harness with the new icemaker - it's slightly shorter, harder to install. Not the issue.
But what made it challenging had nothing to do with the new ice maker or parts - the fridge is a 90's vintage built-in KitchenAid. Documentation is scarce, and consider it immovable.
When the last icemaker died, it did trickle water into the icemaker - and that comes in through an aluminum fill tube. So it froze, blocking the line.
After fitting the new unit, it would cycle, but not fill.
Time to look for the valve.
- diagrams of the fridge show a valve, but no reallocation. Notes on the web are vague.
- in a "normal" fridge, the valve would be lower back, with tubing running up the outside rear, and through.
- fill tubing does connect to the fridge at the bottom - but no visible valve underneath..
- Oh - and while you can cycle the valve if no water is flowing, it doesn't make enough noise to be able to tell where it is.
- It's actually on the top, outside, over the refrigerator section. If you have cabinets above it - good luck.
Fortunately, with wood valence with light, the valve can be seen.
Valve is ok, so back to the frozen line.
Take the icemaker out, grab a towel, and blow dryer to heat up the aluminum fill tube. eventually, got some water out. Takes a while.
Be very careful testing this - you have a 110V unit and free-flowing water very close.
Best to reinstall icemaker and test. DO NOT jumper the plug - it's directly under the fill tube!
Works -
