True chest type freezer tfm-41fl

SOURCE: Freezer is freezing but the outer wall are extremly hot

This is a normal condition.  The condensor coils are in the cabinet and their job is to remove heat which is why it is hot.  You will want to make sure the freezer isn't in a tight spot where air from the room can't flow across it.  Without good air flow it will become too hot and not cool properly and lead to the compressor failing too soon.

have you cleaned the condencer? dan

SOURCE: freezer not freezing

it would apear the stat is the fault. the thermostat is monitoring the temperature of the inner liner and tubing. if the compresor isnt actuly staying on the only part controling it is the stat. if you have the knoledge i would sugest you bypass the contol with the unit unpluged and the plug it in to conferm the fault was the control. p/s you may have a friend who has some knoledge . the control is a simple switch. just enshure the unit is unpluged. hope this helped

ice cream is always the last to freeze and a temp of minus -10 degrees is usually required to get it to get hard. if you put the ice cream in the door it will be especially tough to freeze. a good thermometor is a good investment as you can observe the temps. usually ten degrees or 20 degrees is what they run. yes they do cycle on and off as long as they hold temps thats good. the outside of the freezer gets warm because the hot compressed refrigerant is spread through piping near its surface giving up its heat of compression . setting the stat to max will freeze the ice cream eventually but utility bill suffers . good luck

yes you may encounter problems come sumer depending how hot it gets where you live but during the winter you should have no problems.
