Sub-Zero 542 Ice Maker Broken - No Ice

Hi,

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!

Thanks!
Jim

    Yes, it's a built-in fridge/freezer side-by-side, model 542. It looks like the ice maker and drawers below are all inside of some type of slide-in thing, but not sure if I can just remove screws and all, and if there is a way to get a better idea of the problem before tearing things apart.

    Thank you for your help!!

    I have the same issue. Does anyone know how to get to the water valve? There is some false panel on the back of the freezer but not sure how to remove everything and even if that is were the valve is.

    Can anyone help or can send a service manual that shows more details?

    Thanks!

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.

  1. Check to see if water is flowing @ the water inlet valve @ the rear of the unit. You can remove it and clean if out-then put it back in service. You can purchase a new valve -- maybe @ home depot.

SOURCE: Kenmore Bottom Freezer 596.71103101 Ice maker not working right

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:

  • It may be turned off. Look for the wire along the right side of the ice maker that looks a bit like a coat hanger. If the wire is in the raised position, the ice maker is turned off. If so, try one of these:

    • If your ice maker has a small red plastic lever, lower it to lower the wire.

    • If there's no plastic lever, simply lower the wire.

    In either case, the ice maker should begin producing ice again. Also make sure that the temperature is 8 degrees Fahrenheit or lower. If the freezer is too warm, the ice maker won't cycle properly.

  • The ice maker fill tube may be blocked with ice. If so, melt the blockage using a hair dryer-but be careful to not melt any plastic parts! Also replace the water shut-off valve or water-inlet valve, or both, if necessary.

  • The ice maker head assembly may have broken parts. Look to see if the gears are broken. Check to see if the small plastic arms that rest against the ice rake are broken. If the ice maker head assembly is modular and you've found broken parts, you can just replace it.

SOURCE: Whirlpool Gold Refrigerator (GS5SHAXNLOO) Ice maker not running, some ice in maker melted together

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!

Sub zero 650 slow ice maker


Hi Maureen,

Your sub-zero 650 should produce about 8 cubes every 2 hours. It sounds like the heater beneath the ice maker may be wearing out. Ice makers use a heating mechanism to warm the cubes in the mold and force them to easily eject. If the heater is failing in the back slot, it could cause the ice cube to get stuck. If this is the case, you usually need to replace the part or the entire ice maker.

It is also possible the mechanism isn't properly aligned. You could try adjusting it.

You can find two manual on FixYa here: http://www.fixya.com/support/p24667-sub_zero_650_o_bottom_freezer

Otherwise, I suggest contacting their customer service or a technician: http://www.subzero-wolf.com/contact-and-support/index.aspx

Best of Luck!

Subzero freezer with ice maker. Ice melts and refreezes, into blocks of ice. What could be causing this?


Good day,
In most cases it is the water valve that feeds water to the ice maker well. The valve is energized by the ice maker to fill for 7 seconds and then shut off promptly.
The valve will many times dribble water into the well after shut off, causing an overflow problem.
The fix is a new water valve kit.
The only other possibility is the freezer temperature going above freezing from time to time, but is a rare problem.

My subzero 650 ice maker drips water w/o making ice. Makes a mess with ice build up. I had to turn off water lined to stop the ice maker from dripping. Turning off the ice maker switch did not stop the ice...


Good day,
No, a new water valve should solve that problem. The diaphram in the valve is not completely closing.
Very common problem.

Thank you for using FixYa

My subZero Model 245 Icemaker stopped making ice


Ice maker, I don't know where you can find the manual but I'll give you a few ideas of what to look for. First make sure that the inlet tube is not frozen over. Next, look at the center gear on the module and see if the clips in the center are not broken. If so you will have to replace the module. The ejector blades should be at the 2:00 position when home. If you get a jumper wire and jump T to H, this will by pass the bi-metal and run a cycle. The ice maker should fill at around the 12:00 position. Test points L & N will verify if you have 120v to the ice-maker. Test points L & H will test the resistance of the heater, 72 ohms. plus or minus 10%. Hope this gets you going, Catriver...post back.
