We have a sasung refrigerator, it makes a horrble noise when the ice maker is filling up with water, we think it may be air in the line, any suggestions on what may be causing this?

most times I see the tray and fill tube ice up its due to a leaky fill valve , this valve should close tight after filling tray , but sometimes they leak just slightly then everything freezes up in a block of ice

fill valves on most all units is located in back lower left corner , just follow the water line in the back of unit

Bonjour,
Ice makers can clog. The water valve can stick open or closed or even not work at all. The water fill nozzle can clog with ice or food. If the unit has been moved the water line could be kinked or the water filter may be clogged. Maybe the water valve for the ice maker water line is turned off. Is there one under the sink? Inside most ice makers there is a thermostat that tells the ice maker that the water is frozen and it's time to dump the ice cubes. That starts a geared motor running to dump out the cubes. And in some cases a mold heater is turned on to help break the ice cubes loose. A lot of ice makers have a cam attached to the motor that turns with the shaft. When the ice cubes are gone the cam starts a timer to refill the ice maker with fresh water to make some more ice cubes. Most "fill" cycles of ice makers are "timed fill". The fill cycle has to start and stop to get fresh water into the ice maker. There may be another thermostat that monitors the air temperature where the ice maker is mounted. If that thermostat thinks the air is not cold enough to freeze water nothing happens. If all the steps don't happen at the right time no ice cubes are made.

Check the water line that goes from the water fill valve to the ice maker to see if it's frozen shut.
You can remove the ice maker water line from the water fill valve and see if you can blow air through it. If you can't blow through it then its frozen shut.
Sometimes they freeze shut if the water inlet valve was seeping a little water past it when it was off.
If that is the case you have already replaced it so after thawing the water line out you should be good to go.

Water leak and noise are due to wrong temp setting or malfunction of defrost cycking.Keep temp setting between 3 and 5 degree centigrade. Due to over frosting, the freezer fan fan hits over the ice and working to cool fridge compartment.And also check defrost timer, and heaterworking properly to defrost in time. And if your ice maker is making sound, due to:

• You will hear a buzzing sound when the water valve opens to fill the water reservoir for each cycle.
• Rattling noises may come from the flow of the refrigerant or water line. Items stored on top of the ice maker can also make noises.
• The high-efficiency compressor may make a pulsating or high-pitched sound.
• Water running over the evaporator plate may make a splashing sound.
• Water running from the evaporator plate to the water reservoir may make a splashing sound.
• As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your ice maker.
• You may hear air being forced over the condenser by the condenser fan.
• During the harvest cycle, you may hear a "thud" when the ice sheet slides from the evaporator onto the cutter grid.
• When you first start the ice maker, you may hear water running continuously. The ice maker is programmed to run a rinse cycle before it begins to make ice.

Hope, it's helpful>

What you think is probably correct. Water valves can seep water and freeze the fill tube. Remove the ice maker and the fill tube remove ice from the fill tube and replace the water valve.

It needs to get the air out of the line before the water will fill the tray. When the line is opened up air will get inside and needs to bleed out first. On units with a water dispenser it is good to run it after a filter change to make the ice maker usable faster. An ice maker times the water for a fill not the amount of water since it uses a pressure regulator, so it does not know there is air in the line.

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

the frig ha a plastic resivor that has air in it

you can bleed the line by continuing to use the water dispenser and diverting it into a pitcher

you can make a transfer funnel etc out of tin foil should not take more than 2 containers ( 1 /2 gal each)

replace the water fill valve it is at the bottom where the water line conect to the unit

If it is only the fill tube that is freezing up, or getting full of ice, than your water valve is leaking (letting drops of water thru to your ice maker and filling the icemaker fill tube up and freezing). If this is the case, replace the dual water valve (part # 1071263) located in the back of the refrigerator, just follow the water line from your wall into the refrigerator. Make sure you turn off the water to the refrigerator and also unplug it. The dual water valve is the one that has two water lines, one going to the icemaker and one going to the water dispenser. On this model, I think you only have one water valve. On some you have two, the primary water valve and a secondary water valve (the dual valve). If this is your case, I would highly recommend you replace both. As far as the Refrigerator side freezing things up, I think that is a whole different issue. Please post back.
