Product review (5 stars): Fixed my problem - was not making ice correctly
Used this on the end of my ice mold (Whirlppol icemaker - what a piece of junk) that meets the thermostat.  Was required to make the maker function properly.  If you maker is not making ice correctly, see if the gray putty between the mold and plastic housing that houses the motor and thermostat is in tact. If not, replace with a dab of this stuff and should do the trick.  Too bad the tube is about 100 times more than I needed....but beat a service call!
