GE Profile with auto ice dispenser (Model PSS23MSTE) does make ice, but will not drop it into dispenser. The other day the power went out for a few minutes then came back on and it immediately dropped, but since that won't drop cubes. There is not a metal "arm" that gauges ice on this on this unit-- or at least none that I can ascertain.

There is an adjustment for the "harvest" bar (The bar you lifted up). That bar you are lifting up tells the ice-maker that the cubes have fallen into the ice storage and starts the ice-making cycle over. It is also the Limit switch for the ice level in the storage container ... if it stays up for preset time determined by the manufacturer it stops making ice... most all ice-machines use the same devices. they vary little in design. Sometimes you can just gently bend the bar down to the point where it turns-off the machine at the level you want ... unless you can get to the adjustment hinge you can adust it there. For the fact it goes off when you lift it all the way up tells me the harvest switch is turning the ice-maker off.

Sound like maybe a dispenser board short... you could try taking of the top hidge cap on the freezer side unplug the power to the board there for 30 minustes or so plug back in and see if it can reset to default and try that before u have to change board

check your owners manual for a water filter, make sure trip arm isn't stuck closed and not letting water in to freeze.

THE WAY A DISPENSER CHANGES FROM CUBES TO CRUSHED ICE IS BY RAISING AN ARM THAT RUNS ALONG THE BOTTOM OF THE ICE BIN. IF IT SETS FOR A LONG TIME, IT CAN GET A BUILUP OF FROST OR ICE THAT KEEPS IT FROM MOVING. PULL THE ICE BIN OUT AND TRY TWISTING THE END OF THE ARM MANUALLY. IT SHOULD OPEN A DOOR AT THE FRONT OF THE BIN THAT WOULD ALLOW THE ICE TO BYPASS THE CUTTER ASSEMBLY.
ALSO,WITH THE ICE BIN REMOVED, PUSH THE DOOR SWITCH BUTTON CLOSED BUT KEEP THE FREEZER DOOR OPEN. WHERE THAT ARM GOES IN THROUGH THE BACK WALL, CHECK FOR MOVEMENT OF A ROD UPWARD WHEN YOU CALL FOR CUBED ICE. IF YOU HEAR A LOUD HUM BUT THE ROD DOESN'T MOVE, YOU MAY NEED TO REPLACE THE SOLENOID ASSEMBLY IN THAT MODULE.

More than likely, your water line is freezing up in the door. You can remove all of the ice cubes and lower the freezer temp to about 3. Leave the freezer door open for about 5 minutes or so and if this does not work, leave the door open a little longer. Also, disconnect the water line at the base of the freezer door, near the floor, and press the dispenser lever. If you have water there, you most likely have a frozen line in the door. Changing the water filter often will help but it is not the answer and is can get quite expensive. By the way, Make sure to hold the dispenser lever forward for at least a couple of minutes each time you test for water flow. If you do not get water at the connector at the base of the door after you have disconnected the line, you have a problem with the valve in the back of the refrigerator.
