Defrost timer?

Can anyone explain the whole process? First let me explain my situation. My freezer seems to run fine. Then all of a sudden shuts completely off. I discovered the reset on the back and it turns the freezer back on. After searching, I realized what I'm touching is the defrost timer. I've always panic and never waited for the freezer to turn back on by it's self. If it acually would have. It's a 1990 Victory freezer with a 50636401 timer. All fans turn off and the freezer is silent when this trips. Is it working? Do I have a bad timer or something else. This stuff is all new to me. But, I'm learn'. Thanks
Merry Christmas!

    As far as I remember, it is more than just a simple thermostat.
    Which itself runs me about $50 to replace.
    Don't know what they run down there.
    - for me, a brand new freezer is only a couple hundred, simpler to replace the whole unit.
    Unless it is an expensive TRUE model or something, but you did not specify.
     
    It's more complex, with a timer, and a heater/evap unit.
    This might help.

    OK so you may have three things going on here. One, the condenser maybe going out or the unit needs recharging if you can hear the freezer in the first place. As such simple maintenance can prolong the units useful life. However this can be expensive. As much as half the cost of a NEW unit. Second, that the unit is simply reached its designated temperature and does not need to run the condenser to maintain its temperature to maintain that level. If so, it may turn back on when the internal temperature reaches a certain level. By resetting the defrost timer you may be getting the unit condenser to come back on and letting the frost build up. Third and the most unlikely, is there is a ground fault in the unit as sometimes the defrost timer can act as a fuse relay. Have only seen this in units pre-1970's.

    Looks like mine turns off for 45 minutes at 8 hour intervals.
