Haier model PRCS25 ice cube size it too big. How

cubes set too large
Adjusting the Ice Cube Size: 1. Press and hold the "Adjust" button for approximately 3 seconds until the Green Indicator starts blinking, release the button. The unit is now in Ice Adjustment mode. 2a. Press the "CLEAN" button to decrease ice cube size. The Red Indicator will flash as you lower in size and will blink when you have reached the smallest possible setting. 2b. Press the "MODE" button to increase ice cube size. The Yellow Indicator will flash as you increase the size and will blink when you reached the largest possible setting. After 10 seconds without any operation, the unit will return to the previous mode. NOTE: • During the ice adjustment mode, if the "ICE FULL", "ICE MAKING" and "ICE HARVEST" LED's all blink simultaneously, this means setting is at the regular (middle) size. • When the machine is in the cleaning stage or ice full stage, the ice size cannot be adjusted.

To adjust the cube size raise or lower the float located to the left of the pump, raising it higher will reduce the size lowering it will increase the size.

Try cleaning the whole water system, then clean the condensor.

With out the full model number it is hard to say. Most 106 model referigators have a modular ice maker. If you take the cover off of the front of the ice maker and look on the right hand side of the motor module you will notice a small plastic adjustment screw. If you turn this screw you can adjust your water fill time to the ice maker.

DO THE BASICS:
Change the water filter
Add ice machine cleaner and go by the directions.
What should be kept clean?
There are 5 things to keep clean:
1. The outside cabinet & door.
2. The ice storage bin.
3. The condenser.
4. The ice making system.
5. The ice scoop.
The ice storage bin should be sanitized
occasionally. It is usually convenient to sanitize the
bin after the ice making system has been cleaned,
and the storage bin is empty.
A sanitizing solution can be made of 1 ounce of
household bleach and two gallons of hot (950F. -
1150F.) water. Use a clean cloth and wipe the
interior of the ice storage bin with the sanitizing
solution, pour some of the solution down the drain.
Allow to air dry.

How to clean the condenser.
The condenser is like the radiator on a car, it has
fins and tubes that can become clogged. To clean:
1. Remove the kickplate.
2. Locate the condenser surface.
3. Vacuum the surface, removing all dust and lint.
Caution: Do not dent the fins.
4. Replace the kickplate.
Winterizing
1. Clean the machine as explained on the next
page.
2. Turn off the water supply.
3. Drain the water reservoir. See page 24, Spray
Pump Repair and follow the instructions to remove
the pump hose (step 2, bottom hose only).
4. Disconnect the incoming water line at the inlet
water valve.
5Remove control box cover and turn the timer
into the harvest cycle.
6. With the machine operating, blow air through
the inlet water valve; a tire pump could do the job.
7. Drain pump models should have about 1¤2 gallon
of RV antifreeze (propylene glycol) poured into the
ice storage bin drain.
Note: Automotive antifreeze must NOT be used.
8. Replace control box cover. Switch off and
unplug the machine.

CUBE ADJUSTMENTS
There are three items that may be adjusted: Cube
Size, Harvest Time, and Bin Level. Note: Cube
Size and Harvest Time adjustments should only be
done by a qualified service person.
Cube size control.
The cube size control should only be adjusted to
bring the cubes to the correct shape, the overall
size cannot be adjusted. Try to adjust the cube
size control when the ice machine is in the harvest
cycle, or in the first 10 minutes of the freeze cycle.
1. Open the door and remove the control box
cover.
2. Locate the cube size adjustment screw, and to
make fuller cubes, turn the screw clockwise about
1/4 turn. This will make the freezing cycle longer.
3. To shorten the freezing cycle and make cubes
that are not as full, turn the adjustment screw 1/4
turn counterclockwise.
4. After the next freezing cycle, the cubes should
have responded to the adjustment, if another
adjustment is required, do it early in the freeze
cycle.

That has to be a faulty control wouldn't you think?
The cube size control should only be adjusted to
bring the cubes to the correct shape, the overall
size cannot be adjusted. Try to adjust the cube
size control when the ice machine is in the harvest
cycle, or in the first 10 minutes of the freeze cycle.
1. Open the door and remove the control box
cover.
2. Locate the cube size adjustment screw, and to
make fuller cubes, turn the screw clockwise about
1/4 turn. This will make the freezing cycle longer.
3. To shorten the freezing cycle and make cubes
that are not as full, turn the adjustment screw 1/4
turn counterclockwise.
4. After the next freezing cycle, the cubes should
have responded to the adjustment, if another
adjustment is required, do it early in the freeze
cycle.

If you pull the front cover off the ice maker,You will see an adjustment srew with + and - symbol ,just turn that srew.

Please rate this a fixya

remove front cover to view control panel. there is a cube size adjustment there. use a small screwdriver and turn it counterclockwise to make the cubes smaller

Most ice makers have an adjustment screw to control the cube size. Its usually hidden behind a plastic panel on the front of the ice maker. A quarter turn either way and some trial and error testing should get you pointed in the right direction to your ideal ice cube.

hoshizakis make ice cubes depending on the amount of water in the sump. if you are starving for water the sump only partially fills in the fill time allowed . then it makes ice until the water is used up and the float switch drops and the cubes are little slices. you can adjust the size of cubes you want by raising or lowering the float assembley in the sump. if its to low the water rises and the float rises and tells the machine you happy with little slices. if you raise it up to max height you can max fill before float satisfies and max ice cubes. But if you are starving for water the time to fill will run out before the sump fills and cubes will be small no matter where you set the floats assembly. water starving can be due to crud in the water line, to small a water line, most hoshizes take a half inch line ,or a clogged water filter. if you suspect a filter take it out . if fill is drastically improved you need a new filter. be aware that starving for water on a hoshizaki will eventually lead to broken evap plates. big time expensive.good luck. i put in a new machine ruined by starving water and the new one made little chips of ice real quick. i finally pulled the filter out and voila! big cubes and great production.
