Ice is forming around fan in back of freezer compartment

It's probablly caused by air leakage through the ice room fan electrical connection inside the freezer. Behind the back wall inside the freezer, the icd fan is the fan that blows air up to the in-door icemaker. The plug on that, into a molded plug on the back of the feezer compartment, is a red plastic part with three wires in it. Try filling in around the wires and the red plastic with a bit of silicone. (if you replace the ice room fan, the new plug comes with a rubber filler which seals this spot). (PS. Next time, avoid Sears)

The model number you post appears to be incorrect.
The buzzing was from the evaporator fan blade hitting on some ice build up. Getting to it on a bottom freezer refrig is a bit of a pain in the back side. If your model has a pull out freezer drawer, that has to be removed, the icemaker removed, one side of the drawer supports from the freezer wall, all to allow you to remove the back wall of the freezer to get to the fan. You may be able to just thaw out the fan and surrounding area then which will get your refrig cooling again, if the ice was just around the fan area. On the pain in the but repair scale of 1 - 10, this one rates at least a 7.

need to remove rear panel inside of freezer section. check for normal operation of evap fan motor. check for ice build up on evap.

I also had a loud fan and it was caused by ice build-up on the fan in the back of the freezer. From inside the freezer, I removed the plastic grill that covers the fan (I think I also had to remove the side rails and ice maker) then just let the fan defrost in the sink. Made sure it was nice and dry before putting it back in or else ice would just form again. I also took a sheet of plastic and put it between the ice maker and fan grill to stop water from dripping onto the fan and haven't had a noisy fan since. I just need to remove the ice build-up from on top of the plastic sheet every now and then, but that's much easy than taking everything apart to get to the fan.

the fan behind the ice maker is iced up poss fault defrost heater gone try total defrost faor a list 36 hrs restart it noise come back then you need to repace the defrost heater hope this helps

nothing to do with light bulb - noise is probably fan hitting ice that has built up. to check, remove back panel inside freezer and check for ice build up. melt off with a hairdryer and get back to me if i'm right

I had the same problem. I found the buzzing noise was caused by ice build up around the fan motor inside the freezer. I believe water must have leaked down around the fan during a defrost cycle. I removed the ice maker, the ice cube bin and ice dispenser auger motor. It sounds complicated, but it isn't too bad. The ice maker and auger are connected with quick connect plugs. So just unplug, remove the screws and remove them from the freezer. You will need to remove several other screws as well, I believe 11 in total as well as the top freezer rack. This will give you access to the white aluminum panel that runs from the top of the freezer to about halfway down the back of the freezer. After you remove the aluminum panel you will see the fan about half way down the freezer. I found a lot of ice around my fan. The fan blades were hitting the ice causing the buzz. Remove the ice and the buzzing is gone. It took me an hour to complete this repair. I hope this helps.

suspect you have a problem with the defrost system and hence the noise with the fan. take back panel off inside the freezer and if i'm right, melt ice off with a hairdryer. get back to me to say the results if you want

Sounds like the fan is hitting some ice build-up. If you can access the area of the fan motor you can try a hair dryer to defrost the ice out of it.
