Ice maker noise when filling

Make sure that there is not an ice build up inside the maker at the point where the water enters. The fill tube should not be under pressure. When water is called for a blockage will cause it to leak.

most of the time when that happens first thing you do is make sure water is getting to the solenoid for the ice maker if you have a water despencer you have water the solenoid for the ice maker is normally found in the back of frig near bottom pull frig out till you can get behind it look where water line goes into the frig solenoids for water and ice maker should be there. leave frig plugged up have someone use the water despencer feel whitch one that is replace the other one

it may be the compressor turning off and on

Two main possibilities:
1.) If the refrigerator has an ice maker but you are not making ice, the solenoid valve will open every hour or so to allow water to fill the ice maker. That valve wears out and makes more noise as it ages. There is a metal rod/bar that can be lifted up to stop the ice maker from cycling.
-or-
The compressor and the associated starter cap may be failing and it can make odd noises when it starts back up after the defrost cycle. Time for a professional to take a look.

Ice maker bad or the ice maker water valve mounted on the same bracket as the dispenser is bad. These frigs are prone to bad ice makers after a few years.

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

I have the GE profile Refrigerator with ice maker in the refrigerator compartment. Mine was knocking loudly for long periods of time, so I finally removed the icemaker by removing the side panel in the icemaker compartment held with 1 phillips head screw, disconnecting the electrical plug (unclip), pulling the tab of the icemaker down (on top) and sliding it toward the door, thus removing it. There was ice frozen in the motor compartment that was the problem. I let it thaw out and re-installed. All was OK after that..

I wonder if you just notice the noise now because the leak has you more aware? First things first. Lift up the arm on the ice maker (a few hours prior to attempting service) to stop it's operation. You need to roll the unit forward to give you access to the back. You'll see a plastic tube that runs from the bottom compartment (water valve) to the ice maker fill tube. Lower the arm of the ice maker and observe the plastic tube for the location of the leak. The most likely spot would be at the top. A hose clamp can be put on the fill tube after making sure the plastic supply tube is completely inserted into the fill tube. The fill tube is the piece that goes through the rear bulkhead and delivers the water to the icemaker. It may be neccessary to remove the icemaker to thaw out the fill tube using a hair dryer.

take out the line connection in the back of the icemaker where it goes through the wall check for clogs.

pull the cover of the front of the ice maker. there should be directions as to what way to turn the main gear (use a philips screw driver). advance the ice maker until it starts to run on its own. if water comes in at the end of the cycle then you need a new ice maker. if no water comes in check to make sure the fill tube is not frozen. if it is clear replace the water valve.

Good Luck,
