I have a 19.7 cu ft Hotpoint side by side Refridge/Freezer No Frost CSX20BA. It is 15 years old. The ice maker is not producing as much ice as in the past and the cubes are not completely solid.....more hollow when they are made. Any ideas? I cleaned under/behind the unit (major dustbunnies) w/ shop vac. I believe this ice cube maker was put in by my dad after we bought it....wasn't installed at the store. Any advice would be greatly appreciated! THANK YOU!

very likely a partially clogged filter, but not sure why no light.

Hollow ice cubes are due to low water pressure to the fridge. Water thru the door should have good pressure behind it. This is a good indicator of water pressure. Should be able to fill a glass quickly. Causes for low pressure are self-piercing saddle valves on the water line (switch to drill type (1/4") valve) or reverse osmosis system or filtering system on water line to the fridge. R.O. systems should not be used. Increase water pressure and that will fix the hollow cubes. The loud noise may be the sound of the water valve on the fridge when it is acivated. This sound is normal and some are louder than others.

chances are you have a faulty module (board) sounds like you'll have to call an engineer oput to replace it

SOURCE: Ice maker makes hollow ice! Why?

Not getting enough water into the ice maker. Could be a partially frozen supply line, restricting the total water input, or it could be that the timer needs to be adjust.

If the water supply tube to the icemaker is frozen. It will be a white rubber tube on the right side of the icemaker. Warm it with a hair dryer, remove it from its aluminum tubing, and make sure there is no ice all the way back to where the supply tube comes from the water valve. After thawing, your icemaker should start working again.

Now..... why did it freeze? Most likely, there is a restricted airflow to the back of the unit, which is need to keep that aluminum supply tube just warm enough to assure all the water flow OUT of it into the icemaker, and doesn't freeze up on contact. Make sure your coils and the airspace under the fridge are completely clean (vacuuum them well) and it should cure the problem.

To adjust the timer, follow the instructions here http://www.acmehowto.com/howto/appliance/icemaker/diagicemaker.php

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.
