The buzzing your hearing is your motor trying buy unable to start. There are really just two possibilities depending on the size and type of your compressor. For either type you could have a bad starting capacitor. If you have a motor repair shop near by this is an easy and fairly inexpensive fix.
If your starting capacitor is good your compressor is most likely seized up. If your compressor is a small hobby compressor with a diaphram your diaphram has dry rotted and is preventing the motor from turning. If your compressor is large enough to have a piston their is most likely rust in the cylinder that is seizing your piston in place. Generally for compressors less than 50 gallon it's more cost effective to replace the compressor rather than trying to repair this problem.

Are you getting any heat from the condenser? Sounds like the buzzing is the compressor failing to pump.

Mccall FS10-E freezer has been sitting unplugged for two years and now won't cool (I believe it worked before but not 100% sure). When plugged in, there is a constant buzzing from the fan motor. ...

Here are a few thoughts.

Possible a very small freon leak. A low level of freon will cause a "No Cooling" situation.
There is a small possibility that since it sat for so long, that the rings on the compressor may not be sealing properly and the compressor is now "Weak" and does not have the capacity it needs to do the job.
Buzzing from what fan motor? Evap or condenser? If the motor buzzes but runs in the correct direction (rotation) and at the correct RPM. I would not be too concerned about the noise at this time.
I'd start with these items before going any farther.
Let me know if I can be of any further help.

Buzzing noise -Kyoto KU 9577 Freezer

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.

A loud intermitant buzzing coming from the back of the fridge

either the noise is coming form he ice maker fill valve( but if its of and still aking noise i doubt it. it also possible that the noise is coming from the compressor itself, overheating nad trying to restart in which case would give a slight "buzz" noise for 5secs or so then "click" off, and wait maybe 3 min to restart again. look for melted ice andperhaps your ice dream ont as hard as it should be???

Loud buzzing noise from compressor area and freezer not cold enough

I have a 1.5 year old GE refrigerator and freezer. This unit had not given me any problems until 2 days ago when I constantly heard a loud buzzing sound coming from the freezer. I called GE and Best Buy (bought it there) and asked to troubleshoot this over the phone. They suggested sending a technician over for $100 just for the visit + labor + parts which could add up to hundreds of dollars. So, I researched the web and blogs like this. The answer to my problem was simple. Something that I placed inside the freezer was blocking the air circulation vent. So, I turned off the whole refridgerator and I removed everything from my freezer. For good measure I dislodged some ice and frost that had developed over the vent. I carefully put back everything into the freezer, but this time being careful not to block the vent. I turned on the power and voila! No more buzzing sound!!! I hope this works for you too.
