My fridge has an automatic ice maker. It is also self defrosting. My
problem is that ice from the icemaker gets thawed and refrozen so much
that it sticks into a large clump of ice in the back of the tray. It
would seem that if I had an insulated tray that it might slow the
process. I took some cardboard and put it behind the two sides of the
tray that touch the walls and on the bottom. This seemed to slow it a
little but not enough to stop it.

Anyone have another solution?
