freezer problems

Refrigerator & Freezer Repair

Hi; So far I have replaced these three parts;AP3133073,AP430371 and AP3861954, per your suggestion and I am still having trouble controlling the freezer.It always reads below 0;but things never completely freeze. Our Ice-cream is very soft;barely even frozen.I have to keep everything in a chest freezer which freezes solid.I can’t find a t-stat for that one either;but that’s a separate problem.So what can I do now?

                                         Thanx

Is the evaporator fan running?

Yes it is running.I have a thermometer in there and it always seems to be 0 degrees; but nothing freezes completely
