Icemaker Repair II – part 2

The previous post talks about the problem with the ice maker. This is about the fix.
Basic ice maker theory. 1. Put water in a container. 2. Put it in a cold place and 3. wait until it freezes. 4. Warm the container until the ice is loose enough to come out. Repeat.
Automatic ice maker theory. Actually begins with step 3 since this is where you will find the automatic ice maker most of the time. There is a thermal switch that detects when the container (and the ice inside) is at a frozen temperature. When this happens, the switch closes and the motor rotates the paddles. A switch turns a heater to warm the ice mold to loosen the ice. The paddles push against the ice.. The motor will push the paddles against the ice until the ice releases. When the ice releases, the paddles continue around and push the ice into the catcher. At some point the heater turns off and the water is turned on to refill the mold. There is a small slotted adjuster on the side of the unit that sets the amount of water and hence the size of the ice chunks.
My unit was somehow jammed. I poured about 1/8 cup (.03 liter) of water to get the cubes loose. The paddles rotated and the cubes came out. It refilled normally. The water going in made a noise like the mold might have been really hot. The ice made in about 20 minutes and came out normally. I reduced the cube size slightly (clockwise 1/16 turn of the slot with my thumbnail) to reduce the force required to push out the cubes.
It is still working a week later.
