Refrigerator Icemaker Not Dispensing Due To Clumping Ice

Your dispenser may not be dispensing due to clumping ice cubes. The ice cubes in your icemaker may be clumping for a couple of reasons:

Low food load:
The defrost cycle radiates heat into the freezer. The ice in the freezer will naturally absorb the heat. This will cause the ice to melt slightly during defrost, then eventually freeze together in clumps. Increasing the food load in the freezer will buffer the warmth from the defrost cycle and keeps the ice from melting. Make sure the freezer is 3/4 full of food.

Lack of use:
When the ice bin is full, the pressure from the weight of the cubes can cause the bottom cubes to fuse and clump. To prevent this from happening, discard the clumped ice and check the bin periodically to ensure the ice is not building up. If you do not use a large amount of ice, you may turn off the icemaker and stop ice production.
