Question about Frigidaire Freezers
you may have a bad compressor or a bad compressor relay. The buzzing noise sounds like the compressor trying to start but can't. Unplug the unit and pull the relay off the compressor. If it rattles like gravel in side it replace the relay. If it doesn't then you may need to call a repairman to check the compressor. Hope this helps.

If the unit is running but not cooling then check the following.
1. The fan motor behind the rear panel is not running, you will have to remove the panel, being careful not to damage the control thermostat, and inspect the motor, and replace if needed.
2. The defrost system has failed, icing the coil behind that same panel, and not circulating air. There are 3 parts to the defrost system, the main heater, a calrod unit mounted on the bottom of the cooling coil, a defrost control thermostat which is located on that same coil, but on the top. It is a small 1" round disk with 2 wires coming out of it.
Lastly, a timer which is located on the back of the machine and determines how often the unit defrosts.
If you have an ohm meter and know how to use it, you can test the heater and control thermostat for continuety if the coil is indeed iced up. If not iced up, the test will not work.
To test the timer, you take a screwdriver and with the machine on, turn the shaft clockwise until it shuts off. wait 35 minutes. If it turns the machine back on, it's O.K. If not, it needs replaced.
A tutorial on defrost systems is at the end of this post.
3. If none of the above work, then it is in the compressor/sealed system. This machine has had many issues in this area and is a serious problem unless...........
The unit is under 5 years of age, then warranty will cover the repair.
