This ice maker never would automatically turn off when the ice basket fills up since it was new in 1990. The owner"s manual doesn"t say that it should!The part sometimes called the "ice level arm" that is currently supplied through component suppliers is much more complicated than the one that came with the unit.The original arm was a bent piece of steel wire. The replacement (Repair Clinic Item # 1174840) is bent differently and has a rotating white plastic flap attached. I bought one and installed it. It doesn"t help.The ice maker appears to be misdesigned. The arm rests in the down position between ice loads. If the arm is in the up position, it stops the machine from making more ice.When a new ice load is delivered, it lands on the arm. If the arm were able to rise to the up position, but was not able to come back down, it would successfully shut off the maker. But when there is too much ice, the latest load lands on the arm and the arm cannot ever get to the up position.A properly designed ice makes leaves the ice level arm in the nearly-fully up position between cube deliveries, right?Am I missing something?


You are watching: Ice maker won't stop making ice

If the ice maker is functioning properly the arm would go to the full up position PRIOR to the ice cubes being dumped into the bin, THEN the arm would drop back down on TOP of the cubes in the bin. If the level of the cubes in the bin is high enough to prevent the arm from going back to the full DOWN position the ice maker will STOP making ice. If your ice makers arm is not cycling in this manner then you have a defective ice maker. It is not a design problem. This design has been working successfully for decades

FIXED. jackofalltrades is right, of course. The fact that mine has never worked since I bought the house when the icemaker was 3 years old, and the fact that the owner"s manual doesn"t say it shuts off automatically, doesn"t mean that customers would find that acceptable. Mine must be broken. And broken it was.The timer/controller assembly has a timer in it and is responsible for moving the ice level sensing arm with the sequence jackofalltrades described. Inside it, there is an intricately shaped white plastic piece with a Molex part number on it. This picece translates motion of a cam driven by the timer to rotation of the ice level sensing arm. This piece has some small amount of flexibility, presumably so that it doesn"t break if the ice level sensing arm is pushed-on too hard. On mine, the flexible point cracked; it is a point of maximum stress, of course.I repaired the plastic piece by melting it back to shape with a soldering iron. I"m sure it would have broken again at that point, so I reinforced it with two pieces of paper clip. I installed the paper clip pieces by shaping them into the shape of very wide staples and drilling holes to hold them, then gluing in place with epoxy. This was more convenient than waiting a few days for a replacement "controller assembly" for $60, but is not as robust of a repair.Anyhow, it seems to me that the icemaker is prone to failure if you make this mistake: you put anything foreign, even excess ice from the grocery store, in the ice bucket without turning off the icemaker by raising the ice level arm to its Off position. For example, if you put a bottle of wine in a nearly full bucket, on the next cycle, the timer will rotate its cam, pushing this white plastic translator piece to push against a stub on the piece that holds the ice level sensing arm. When the ice level sensing arm can"t rotate fully, the white plastic translator piece will have to bend. It is designed to bend without cracking, but mine sure didn"t.In summary, the repair is to replace the timer/controller assembly, and the cause of the problem is likely to be user abuse from putting foreign items in the ice basket without turning off the icemaker.Thanks again to jackofalltrades for confirming that I should work on it.
