No ice cubes from ice cube maker

Happen to locate your site by Google. Was impressed and really pleased to find a schematic and directions to find and remove and specs to test the water valve and Defrost thermometer using an electric multimeter. You cannot tell by "looking" at a component if it is still OK.
So I put all the freezer contents into my beach cooler. The repair went as follows.
1. Removed the 6 screws from the back panel and pulled it out of the way.
2. Located the defrost thermostat and pulled it off of the coil.
3. Pulled the two connections off and took it to the bench to test. It showed no readings indicating it was dead.
4. Ordered a new one which came in two days.
5. Had to change the electrical connections using wire nuts.
6. Reversed the process plugged the refrigerator back into the wall. It started and later on I was getting ice cubes.
A great experience. Don't mess with repair guy as they normally are not up to speed on all devices and you are paying for them to learn how to repair your appliance in several trips. Probably using this site. If you can follow instructions, you can do this stuff.
Note. I tested the Water valve using given instructions. More time is used moving things around than the actual repairs. I avoided $150.00 for a new ice maker unit.
