Amana Refrig.BX20RE Bottom freezer is running but not freezing. Suggestions?? My frig is an older model. Amana model BZ22RL freezer on the bottom.

The freezer door was not off that whole time, but it will not freeze now, even on max freeze it is only a regular frig temp inside. The top frig section is working
