My commercial ice maker is making a high pitched alarm sound

I would change the filter first. then just get a new ice maker. most are replaceable.

could be the ice maker or the evaporator fan motor.you can try lifting the arm up on the ice maker and see if it stops,this will shut off the ice maker.also when you open the freezer door to lift the arm on the ice maker the evap fan motor should start when you open the door,you should hear it blowing around,is this the noise you hear?these are the two things i can think of that could make a noise up top,if not it could be the compressor or the condenser fan motor but these are down the bottom back of machine but still could be the problem,if the ice maker and evap fan motor both in the freezer are ok pull out the machine and remove the bottom back panel and check to see if the noise is coming from there where the condenser fan motor and compressor are,you're going to have to do some detective work to find the noise,hope this helps you out.

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>

Make and model number please.

I struggle with the same thing, it's like an apocalypse alarm for my poor dog. I have covered with duct tape which muffles, but does not come close to silencing this culinary menace. May delve further and take the waffle maker apart to find the alarm source. It's a great waffle maker otherwise, we just don't enjoy them as much due to the noise and affect on the dog.

Ice maker could be stuck with frozen ice on the rotator look over and if you see some turn ice maker off and use hairdryer to free up

Hi,

This noise is most likely coming from the evaporator fan motor that is located behind the panel just below the ice maker. There is an air duct that the fan blows through to cool the ice maker that is why the sound is heard in the ice maker area more.

The noise does not hurt anything but the motor can be replaced if it gets too annoying, it is a fairly common complaint. The part number for the motor is WR60X10185 and runs about $60.00. It is a bit challenging to get to but can be done with a bit of patience by removing everything in the freezer and taking the back panel off the inside of the freezer.

check water valve for ice maker or maybe compressor

hi,

periodical clean can smooth the operation of your ice maker.
