It's coming from the freezer. I can hear it behind the fridge but not from the fan/vent area where I expected. I defrosted it and it seems to have stopped. The other problem is that water collects on the bottom of the fridge. It's leaking from the door. Is this leaking behind and down into the freezer blocking the vents and causing the buzzing sound?

Re: Fridge makes a buzzing sound.
Replace the relay/overload device and you will be fine. This is the
item that actually starts your compressor. Right now it is shorted and
can only try to start your compressor. If you want to order online then call 570-622-6441. Thank you Sir, Have a nice day and do rate this solution.

I had something similar in my White-Westinghouse fridge a few years ago. The bearings in the fan motor that circulates cold air went out. Unplug the fridge and remove the grille assembly at the back of the freezer. The fan will be behind it. Try spinning the blades with your finger. If they turn hard or if you feel excessive resistance, the motor is bad. Also, check to make sure insulation hasn't gotten into or is rubbing the blades. It's an easy fix if it's not under warranty. Usually two screws/bolts hold the motor in place, and a two-wire electrical connector. Don't forget to turn the fridge back on after checking it.
If you can pull the unit out from the wall, find the motor compartment. There, you'll find a black can with the motor and compressor inside it. This usually creates vibration when running. Check the compressor's mounts, to see if they need tightening or have rubber grommets that have rotted away. The sound could also be coming from a fan somewhere in the machine. There might be a fan in the motor compartment. Find the vents inside the unit that blow cold air. Check the guards to see if a foreign object could have made its way into the vents and jammed a fan. Make sure you unplug the fridge before you stick any hands or tools someplace they wouldn't normally go. You may want to let the unit run while peeking in with a flashlight to locate the source of the vibration, but beware of moving parts and a shock hazard.
If you had an electric fridge the problem is usually the evaporator fan motor ($30). I suspect that you may have the same problem. Generally, freezers are cooled only, when the fridge needs cooling, the evaporator fan comes on and blows cold air from the freezer to the fridge compartment. The advice below is for an electric fridge but may also work for you, it's worth a try I suppose.
Check to be sure you can get a replacement fan first, they last about 4 - 5
years. Available from a parts supplier or electric motor company.
Unplug fridge, or disconnect gas etc. Fan should be located usually in top of freezer behind a vented cover
plate. Remove cover, remove screws holding fan in, may have to cut
Replace with new motor, make sure the fan spins the same direction (CW
OR CCW) as your old one, if you don't know which way it should spin
then be sure it pushes air into the freezer area and
doesn't spin backward drawing air from the freezer area.
That is usually the evaporator fan motor ($30). Check to be sure you can get a replacement fan first, they last about 4 - 5 years. Can get from a parts supplier or electric motor company. Unplug fridge. Located usually in top of freezer behind a vented cover plate. Remove cover, remove screws holding fan in, may have to cut wires. Replace with new motor, make sure the fan pushes air into the freezer area and doesn't spin backward drawing air from the freezer area.
It sounds like your evaporator fan motor, they last about 4-5 years. Try to see if the buzzing noise comes from the motor, usually in the freezer compartment behind a vented cover plate
The freezer is usually cooled by the compressor, the fridge is then cooled by an evaporator fan motor ($30). If this fan seizes or slows down then the fridge warms up (it sometimes starts squealing before this happens). It could be that your drain hose is clogged or frozen. Maybe the temperature adjuster go bumped.
If you think it is the evaporator fan motor:

clean the coil behind the fridge or under the fridge (where ever they are) and make sure both fans are running, the one in the freezer and the one underneath. If that don't work you may be low on freon change fan motor
Is there ice build up in the freezer? Ours does this we have to remove the bottom & above draw & bang the back plate until the ice built up behind it breaks off & falls down onto a tea towel & then you hear the fan start whirring again, it sounds brutal so wrap your hand in a spare tea towel, but bash away till the ice comes out & fan whir's again, as this fan circulates the cold air into maintaining fridge temperature ?? That's the only way ours then chills fridge again, so much for frost free fridge freezers eh! ??
It sounds like the condensor fan motor is seizing up. This is the fan that cools the compressor down. Does the outside of the fridge feel excessively hot to touch? Can you feel air being circulated under the fridge or behind the fridge? It could also be a faulty defrost timer. Try to identify where the buzzing is coming from and if it is the condensor fan you can put a normal standing fan behind the fridge, blowing onto the compressor untill the repairman can get to you.
