Product review (5 stars): solved ice-over problem with Haier HTQ21J*SS
This kit fit my Haier freezer/refrigerator (model# HTQ21J*SS) perfectly.  It was relatively easy to install.  The old fan was not working and as a result, the freezer would ice over while trying to get the refrigerator compartment cold.  I now have the thermostat set much warmer than before and the fridge is quite cold.  The whole freezer/refrigerator unit is now running much more efficiently.
