Icemaker makes 2 dumps of ice & then shuts down.

to see if icemaker is still good pour a 1/2 cup of water into tray and wait for a day. make sure shutoff arm or switch is on or down (arm down) if it makes ice then the icemaker is ok. if it dont then hold up.
if it makes ice then either the water pressure is too low (or no water) or the water valve is bad. (to check water valve you need a volt meter).
ok back to hold up part... the icemaker actuallys controls the water valve so you can have no water but that doesnt mean the icemaker is bad. so here are the three possiblities to your problem:
ice maker
water vavle
not enough/no water
before you buy anything let me know and we can go over this again
hope this was helpful (or confusing sorry)

The water inlet valve on the back of the unit where the water supply comes in can have a slow leak and will cause ice to buildup and block the fill tube. Disconnect the ice maker line from the valve and watch to see if it has a slow drip. It doesn’t take much to eventually block the fill tube.

Pour about 1/2 cup of water into icemaker ( unless ice is already there ) . If the icemaker dumps the cubes , then the water valve is bad . If it doesn't dump , and holds the frozen cubes , replace the icemaker . Also check your coils to make sure they are clean from dust , lint , etc . Check the fill tube going to the icemaker , to make sure it isn't frozen with ice . If it is , then watervalve is still bad (leaking ) .

arm down ...Pour about 1/2 cup of water into ice maker . If it dumps , replace the water valve . If doesn't dump , replace the ice maker . Also make sure the coils are clean of dust , lint , etc...

first off, make sure its under 17F in freezer as icemaker will not start above this...you need to make sure the icemaker is coming on..if so, you may just have a bad water valve. I'd put four ounces of water into the mold and see if it starts by itself dumping out your ice. if it dumps out your ice..look to see if the inlet tube that brings water into your i/m is not frozen up with ice in it..if it is, defrost with hair dryer and wait and see if it starts to work ok dumping ice.if it starts to work ok..replace fill valve..

If you find everything looking normal and your sure no ice plug in fill tube..you can try to start i/m manually..if your confident enough to work with tools and electricity...find the T and H they are close to each other on front of i/m. take an insulated wire and make a jumper that each end has 1/2 of end stripped of to go into i/m T and H..keep in there for 30 seconds and i/m should start on its own..remove jumper and either put i/m back or be ready to catch water should it come on. if no letters on front of i/m just gears. find the small 5/16 gear and turn until rake arm starts to come up. this i/m should start on its own ... if it starts and runs fills, replace i/m...if it starts , but does not fill..your inlet valve may be bad. it helps to have a volt meter for this.. you can remove top and find valve up there or its under the bottom front vent plate. locate wires that go onto valve. use your volt meter to check for 111-130 volts when you restart your i/m as already talked about. remember, it will take several minutes before you notice anything..the i/m needs to cycle first and get to the spot it fills..if you get power and no water and your sure there is water..the inlet valve is bad...

Pour about 1/2 cup of water into icemaker and see if it dumps the cubes after a few hours . If it does , and icemaker does not refill , then water valve is the problem . If the icemaker never dumps the water poured in , then icemaker is bad . ALSO , check to make sure the coils under refrig are clean of dust , lint , etc . Icemaker has to be 5 degrees to operate .

Hello. You will need to replace the icemaker. The swicth in the head is causing the arm to stay up and is not repairable. If you can get me the model number I can get you the part number.

Dump out the ice, let the icemaker refill the ice container, dump all that out as well and then it should be cleaned of whatever was in the line..
You may want to roll the fridge out and visually check the supply lines on the back of the fridge for contamination as well.

if the reed switch is not tripped at the end of the harvest cycle it will shut down. when ice drops it hits a cover with a magnet on the right bottom corner. the ice falling moves the magnet away from a switch and lets the sequence reset and start over.

It's not too difficult to remove the ice maker. A few screws and the unit will unplug from the fridge. Then you can see why the bar is not turning it off. If it's really broken, check pcappliance.com for parts or a replacement unit. Meanwhile the fridge can keep on working, and you can use trays to make ice.
