I have a CEM Global PS78121 ice maker that has quit making ice after one month of use. I don't have a manual to trouble shoot it and need help. The compressor won't keep running to freeze the ice. Then if it does make some, it won't kick them out to the tray. The cubes just sit in the back and melt.

Hi,
What kind of ice maker do you have??? Hollow ice can be caused from different things in different machines..
It can be caused by not enough water or by water not flowing properly across a plate...amoung other things...

From your description it seems that the refrigeration system of the ice cube is not cooling enough. For this reason the production per day is much lower than it should be. That is why the unit never stops since by the time it have produce new ice cubes the first ones already melt. So it can never be able the ice been container to full enough to rice up to sensor bar.
So first you should reach for the condenser and with a brush and a vacuum cleaner try to clean it from all the dust on it. This will increase the capacity of the cooling system.
You need also to check that the condenser fan is working since if it don't then you will need to replace it.
If the two above case are ok then you need to check the freon charge and it might need some additional Freon charge, but this is not a DIY job since you will need special expensive tools and also a license to deal with freon.
In any case try the two first cases since are the most possible ones.

SOURCE: ICE MAKER RUNS WITH WATER

Hi,

If the ice cubes are smaller than the normal sized ice cubes and the shape seems to be irregular, there might be problems with the water supply. The ice maker could be malfunctioning due to a faulty water inlet valve. In case, the handle on the valve is not in the right position, fluctuations in the water pressure could result in the irregular shape and size of the ice cubes. Ice maker might also not be able to work due to clogging of the water supply valve. A blockage in the filter could also obstruct the water flow. You might have to consider ice maker repair in case the valve contains a bad coil.

Hi, if the fan, evaporator fan is not running, it has failed on you. If you are up to doing this kind of work, you can replace it your self. It is a 120 volt evaporator fan motor, and if you can get it out, take it with you along with the name of the unit, model & serial # to an appliance parts house to get one. If they don't have the exact one, they have universal ones that will fit. This will solve your problem.
