Question about Refrigerators
I'm trying to troubleshoot a subzero 542 ice maker that does not make ice...at least not anymore. One day the arm did not go up as ice filled up and kept making ice until it gummed up the works. We heard a grinding type of noise and shut off the ice maker.
So now we finally removed the ice and all. If I turn it off for a while, then back on, the maker fingers do a full cycle like it's trying to harvest, the arm goes up, back down, etc....like it should.
But then that's it. When it was working, we used to hear other noises (maybe the water valve??) but don't hear any noises at all now. It just runs the cycle once and then sits for hours.
Someone told me to check if the water valve is getting power. I really can't find the valve. There is a false back panel behind the drawers. Is it behind that? If so, how in the world do you remove it to get at the thing?
Anyway, do any experts have a recommendation on a couple of things to check and how to check them? I don't mind buying new parts, but really don't know what to buy, and can't seem to easily see how to removed anything even if I did!
If it has a water filter on the system,it could be that filter housing,water controls are generally in the rear bottom accessed from the rear of box ,not inside where it could freeze

That on/off arm...you should be able to move it and it will likely make a small click when the switch goes on or off. That arm controls the ice making. There is also a float, is it working freely? It has a switch too. Ultimately, the water is controlled by a solenoid valve. It may be defective. Many of these units are removable to test the switches with a multimeter. Turn off the water and remove to test. Some parts are available...some parts are by the unit only.

also discovered if ice box auger not engaged exactly right with auger drive motor, then ice box won't be able to be pushed back the last half inch to engage the secret "turn on the ice maker" switches. Juice storage brackets also won't engage since ice bucket not flush with front of cover.

When the refrigerator was moved, the freezer door may have shifted downward. The switch for the freezer light is on the top of the freezer so it turns off the light when the door closes. The icemaker is also connected to that switch so it won't dump ice when the door is open. The solution is to adjust the door elevation. The easier solution is to attach something to the portion of the door that hits the switch. I used a white coverplate for a wall light switch.

If your ice maker has stopped producing ice completely, check these, in this order:

I have the same model. This has happened to me several times (usually when the door was kept ajar without notice).
Simply open the door, take a common hairdryer and blow at high speed (hottest also) all around the area of where you can feel the ice in the tray, but hasn't dumped yet. It will usually take about 5-8 minutes of consistently moving back and forth around that area. What has happened is the lines bringing water to the trays have frozen over. When you "thaw" them out, the ice made will dump in about 45 minutes. When you hear the ice fall, you will know it's in working order again. I have NOT heard this is a "flawed" icemaker, only that it is hypersensitive to freezing lines when a door is left ajar. In your case, to prevent this from happening again. If you shut the icemaker off again, make SURE you turn off the source of the water feed BEFORE you turn off the ice maker. By doing this, the lines will empty as it makes it's last tray of water. Try that - very confident it will fix your problem!
