Blue Ice cube maker only make 4 instead of 12 cubes ?

are the cubes coming out of the unit? Sounds like the heating element is not activating, to release the cubes prior to refilling. Check electrical connections at the rear of the unit against the freezer wall that they are together. If ok then defrosting element may be defective, Replace unit.

Check if your water filter is up to date, if not check if the ice maker has the option to choose the side of the ice cubes, if so, set it up to medium side.

Open the freezer door.
Pull the ice bin forward about 3 inches.
Push the ice bin to the rear of the freezer until it seats and locks in place.
Then try to dispense cubes.
The ice bin can become dislodged from its locked position and the crushed ice solenoid activates automatically.

Are you having any temperature related symptoms, i.e., soft ice cream that appears to have melted slightly and refrozen, soft breads in the freezer, warm or hot outer surfaces anywhere? If cooling is not a problem whatsoever, are any of your ice cubes smaller than normal, or do you have hollow ice cubes; you would be able to crush the cubes in your hand? If either of these pertains to you, you have not enough water coming to the ice maker, due to a faulty water valve not opening completely, or your water source pressure is low. disconnect your water line from the fridge, test pressure of the water line by placing end in a bucket, turning water on. It will be obvious how the pressure is. if pressure is good to really good, you have a bad water valve on the fridge. If pressure is so-so to bad, change source water valve.
If cubes are not small nor hollow, but rather normal full size cubes, just not enough, you probably have an intermittent problem with your icemaker, replace that.

What is most likely your problem is the crushed ice solenoid. This solenoid, which is located next to the auger motor behind the ice bucket, is failing to actuate when you request cubed ice. Its "home" setting is crushed, and actuates to allow cubes past the crushing mechanism in the bucket. To be certain its the problem, remove the ice bucket, and tape the door light switch in the closed position. actuate the ice dispenser lever, for both cubed and crushed ice. you will see a square hole next to the rotating fork, when you select cubes, it should open. If it does open, there is something wrong with your ice bucket, perhaps the arm is broken, or the door inside bucket is off its snap in type hinge or broken altogether. If it doesnt open, replace the solenoid

Behind the main drive gear is a copper plate. Near the end of the cycle that plate rubs against a probe and energises the water valve. The arcing cause that copper plate to stick to the probe for more than the alloted time (7.5secs) and this causes the water to overfill. I have a page with repair photos and a repair manual: HERE

the apparatus that distributes the water into the tray had been knocked out of balance when taking the tray out. We pulled the ice maker and replaced the apparatus back in it's proper location .

If it is leaking water in the freezer it will more than likely freeze amongst the ice cubes causing a block of ice.

It is more than likely leaking at the rear of the unit, near the valve or fill tube for the ice, this will run up the rear wall of the unit.

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

look inside ice bin to see if auger wheel is broke,sometimes the plastic wheel cut and break,hope this helps-mike
