I inherited an old General Electric model number TFX24SH and would really like to find the owners Manual,Is there any one out there with one to share? thanks in advance, this box is well made and runs circles around the one I "had". I would love to keep it running at optimal,thus the need for the manual.There is a chute at the bottom of the freezer,it has a frozen sheet of ice covering it. I wondered was this the drain? and why is it frozen? and most importantly will it hamper the refrigerator in any way?
