If your icemaker has frozen up, here's how to thaw it:
1) Unplug the refrigerator.
2) Remove the ice bin and any loose ice from the icemaker.
3) Find the fill tube, the white rubber-like hose that delivers the water into the icemaker.
4) Pull the small metal clip off the housing that holds the fill tube down (not all icemakers have this clip).
5) Warm the hose and surrounding mechanism. To do this, you can train a hair dryer on the icemaker to melt any ice blocking the mechanism.
Sop up dripping water with a rag. Be very careful when using the hair dryer near water, and do not stand in a puddle of water; there is a serious risk of electrical shock.
Also be careful not to melt the plastic parts. If you don't want to use a hair dryer, you can soak the supply tubing with hot water, using a turkey baster and catching the overflow in the empty icemaker bin. In some cases, it may be easier to remove the icemaker to thaw out the fill tube.
As a rule, refrigerators are the most dependable of all large appliances. Even so, they do fail to do their jobs adequately on occasion, and when they do, the results can be disastrous because expensive food can spoil in a hurry.
Though most problems call for a repairperson, there are a few simple repairs you can handle yourself by checking the power, controls, condenser coils, and other parts outside of your refrigerator's sealed, hermetic system.
Remember that the best way to lengthen the life of a refrigerator is to clean the condenser coils once a year—or more frequently if they get dirty.
