I have frost build up where ice comes out of ice maker. The frost then clogs the shoot in door.

this can be of some help.. http://techie-doc.blogspot.com/2010/09/fixing-refrigerator-problem-frosting-in.html

only use ice from the ice maker, some frost is normal, but , lower temp in freezer

the gear that pulls it closed is bad. some have small plungers instead of gears

Look into the dispensor , and see if the door flap is closing , or letting warm air in which will cause the frost buildup . If not closing completely , remove the top cover on the freezer door hinge , and unplug the plug . This will remove power to the door . Use a small screwdriver , and insert under the freezer door dispensor control board , and pry outward . Remove the 3 plugs on the board . Next , remove the 4 screws holding the white dispensor cover , and slide outward . At the top right , you will see a solenoid and plunger , which control the door flap . Usually , this plunger rusts on the solenoid . Replace both , the solenoid and plunger ( come together in kit ) Pt # WR62X10055 . Re-assemble in reverse .

You have a bad dispensor flap solenoid . Frost due to flap not closing completely and ice will catch in the shoot .

Air leaking in around the door gasket or the door flam the ice comes out of.

Replace the defrost clock.

outside moister cause making frost, probably you can not do it youself,if you know , do it.

I would contact Hotpoint direct for this one. It sounds like a design fault to me.

What I think may be going on is that the cubes are melting too much, then refreezing lower down.

Set your freezer to -18, and the fridge to +2 and see if that changes things any.

Check seals in that area. Where is the moisture coming from to generate the frosting? - Is the location high in humidity?

Normally the frost is taken away during defrost so if things get worse we need to look at the defrost timer.If freeze temps.begin to rise let me know, Thanks JT
