Water dripping inside ice maker freezes up. it makes ice but the water dripping freezes up. Checked level OK

I see you said you looked and the water valve is off but the only that I know of this happening is a defective water control valve. Like a dripping faucet that when off slowly drips until the ice forms and then one the ice maker dumps ice and tries to refill the water goes in every direction. Unplug water valve to confirm what I am saying, Tell me if it continues to leak. Sea Breeze

Good day,
The most common reason is the ice maker is overfilling because the water valve in the bottom rear of the refrigerator leaks on the off cycle, and needs replaced.

Make sure the machine is level and the ice maker is mounted in the freezer properly to keep it level.

Also, make sure the fill pipe going into the back of the ice maker is properly positioned.

The Ice maker body could have failed but is very rare.

If it overfills and drips, look for an adjustment behind the plastic endcover with a +/- on it. - is less water.

If it continuously drips, replace the water inlet valve on the back where the house water supply comes in.
The water inlet valve on the back of unit opens when the ice maker needs water. If the valve doesn't seal good because of sediment or wear it will continue to drip and when the water reaches the ice maker supply tube it will freeze. You can take the water line off the valve and watch to see if it drips.

the loud noise is from the water freezing and hitting the fan blade in the freezer, is the imkr level? have you replace the filter if has one? is it hooked to an R/O water drinking system? if so remove the filter in frig. last thing to do if others questions ok if the shutoff to that water line going to frig is on the bottom of the pipe shut all the way off then turn back on if you have a dispenser and water is really slow to come out this may clear up the low water pressure. If on most units if you do not have appx 35psi it will not allow the valve inside the watervalve to seat and allows water to dribble by

Try swapping the wires on the dual water inlet valve. Then try the water dispenser. The water should go to the ice maker. This will tell you weather or not the ice maker valve is working and if the line is clear.

Replace the water valve behind refrig , where the wall water line connects to on refrig .

Tube sometimes freezes because of minerals in it hold one droplet at a time until buildup freezes solid. Replace tube first. Water valve allowing some droplets through can also cause this. Tube first-less expensive.

check and make sure that as it makes ice that no water is spilling over or out of the freeze tray. only a set amount of water comes in to refill resevoir. if you lose water during the freeze cycle the water level gets below the blades of the pump and it will sound like the pump is tearing up.

The problem is in the water valve.
The water supply line going to the Ref is connected to a water valve. This valve is not shutting off completely which causes water to drip into the ice maker. This dripping will freeze and eventually completely block the fill tube in the freezer.

Check your ice cube tray to see if it is warped. Mine was. I took the tray off and dipped it into boiling water and remoulded it to the original shape and re-installed it. So far no problems. The tray gets warped because of the ice cube release mechanism. The tray is rotated around until it meets a block on one corner which creates the twisting motion we used to do on manual trays. Over time it tends to warp the tray. Good luck
