I have an Old Yellow Upright frezzer. it's a Sears 725560.
All of our frozzen food it still frozen but it is not frezzing new item.
Also the items on the door are not as frozzen as others. i think i can hear the fan still running but, it could something else!
What could it be?

Does the compressor work?

The model number you posted is incomplete.

The compressor seems to be working and also the fans (the inside the fan and outside fan)
The serial number then may be 106 725560
I unplugged it, defrosted it, uncovered the back panel inside the freezer and the found out that the pipes and drainage were frozen. (i don't know if this is normal)
I put a ziplock bag of water inside the freezer at 9 o'clock this morning, it has been freezing but it has taken all day and still not completely hard.
I noticed that the pipes are accumulating slush again, not as bad as before though! i still don't think it's working 100%

Sorry for the delay.

It is not normal and I'm assuming you did defrost it.

Make sure the condenser coils (under the freezer) are clean and the machine compartment cover is in place.

The evaporator coils behind the back panel in the freezer normally should be covered with thin frost. If it becomes solid then there is a problem with the defrost system. Report it and we will proceed with the troubleshooting.

P.S. The model number you posted is the correct one.
