Hello,

The ice maker fan is located in the freezer and is part of the Grille Assembly ( LG part Name) Which is the removable back panel in the freezer. If you have an error code on the display such as ER/IF the fan is not rotating due to failure or ice accumulation in the fan blade. If you have no error code and the ice maker is not producing ice 2 things to check are...1. On the bottom of the ice maker there is a Test Button. Press and hold the button and the ice maker should rotate, Dump ice cubes and refill with water. If the ice maker does not cycle replace the ice maker. 2. Check freezer temperature. Freezer Temperature must be below 15 degrees to make ice. Ideally freezer temp should be 0 Degrees. If you have warm temps in the freezer there may be a sealed system issue preventing proper cooling.

Hope this helps.

Do not use test button. It test the functions of the board only. You have another issue. Need to know the number of beeps. Usually beeps a certain number of times, then hesitates,then beeps again.

Take a can of compressed air and blow out the dust in the coil. If the coil can't get rid of the heat, it reflects in the amount of ice it produces.

Making good ice. Could be cube size control. Could be a weak compressor. Also these machines are household and meant to run in air conditioned space.

the arm has to be down to produce ice if you have water in machine and freezer is cold enough keep arm in down position and ice should produce

The way I understand how Hoshizaki machines work, the model number is usually what the unit will produce, in pounds of ice. Their manual states: "Approximate production/ 24 hours @ 70 degrees air/ 50 degrees water (incoming)" So, yours should be producing 450 pounds a day, approimately. Since I can not pin point your exact model, I found one that is close. It states: "Ice Production per cycle: 6.6 pounds, 360 pcs." Again, it is not you exact machine. Their web site does not show this model either. So this is the best info I can get for you. Hope this helps.

Check the mold heater.
