The entire backwall of the unit is solid ice. 2

The cooling plate is icing up, sounds like the defrost element has failed, (Fan is hitting ice, hence the noise when shutting door) if there is ice building-up in the rear of the unit, either the defrost timer or defrost element has failed, Defrost the unit for 2 days with door open and NO FOOD inside. turn the unit back on, will work fine for a few days/weeks then return to problem. Solution points to Element, timer or thermo fuse, not costly to repair any of these,. Estimate $90-$120.Any further problems. Let me know PLEASE. Russ

There is a wire lever that allows for the icemaker to be turned off. If it is in the up position the icemaker will not make ice.

Without the specific refrigerator model, it's difficult to say but generally...

1. If the coils inside the freezer are frozen solid with ice, the air can't flow.
   Also, the air needs to flow from the freezer to the refrigerator, but can't because of the ice.
   
   Defrost the freezer completely, if it freezes up again, check #2 or #3.
   
2. The refrigerator control module or timer may be bad, and isn't telling the freezer to defrost at the regular interval.
   
   The control module/timer will have to be replaced.
   
3. The heater wire in the freezer may be burned out, and would have to be replaced.

A control module could be $35-$100, around $30 for a heater wire, plus labor.
I'm not an appliance repair technician, these are only estimates from previous experiences.

Make sure defrost drain is completely cleared of ice and anything else obstructing it. Pouring hot water in it is correct, but make sure it is going all the way through to defrost pan under unit.

I had the exact same issue last night. I would press on the back panel long enough and the noise would go away only to return this morning at 4am. I finally got up took all of the bins and shelves out and found an very large accummulation of ice at the bottom (floor) and walls of the freezer. The ice accummulation was causing the rattling of the tubes in the wall of the freezer (I don't know what you call them), but they were frozen over on one side. I found this out once I took the back wall panel off of the inside of the freezer. I also found the drain hole back there and it was frozen over solid, as well as my ice dispensing unit at the top of the freezer. This whole problem began when I turned on the ice maker 3 days ago. I used my hair dryer and hot water to clear all of the ice from both areas and now it is nice and quiet. Don't know if the acccummulation is due to some defrost switch gone haywire, but at least the rattling is gone and my freezer is back to square 1 for the time being and I saved myself a visit from the appliance guy in the meantime. Took me a total of 1 1/2 hours to do it all.

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

Unplug the unit, open the freezer door and look through the vents at the bottom of the back wall. With enough light you should see the alluminum coil through the vents. If there is ice/frost in the vents your coils are frozen up. Remove the cover on the inside back wall of the freezer you may need to remove the ice maker as well if you have one it just plugs into the back wall there is also a plug behind the cover to the back upper left corner. Once the cove is out of the way use a hair dryer to defrost the coils or leave the unit unpluged for a while. After all the ice is gone reinstall the cover and turn the unit on it will probably work for 3-10 days and then the process must be repaeted again. I replaced the defrost thermostat on mine 2 weeks ago and all is good so far. The defrost thermostat is a little round device that snaps onto the small copper line in the upper right corner behind back cover it has 2 blue wires and cost's about $20.

Hope this helps

It has a plugged defrost drain. You may need to defrost for 24 hours with unit unplugged and doors open. UNPLUG FIRST!! f still leaks, you need to remove floor of freezer, then the back wall of freezer. Remove ice. At center rear under coils is the drain hole that is plugged up. Use hair dryer to melt ice. Pour hot water in this area to uncover drain. With hot water in area, you can put a 1/4 diam. hose or copper pipe in drain and blow into it while pressing down. It will slowly go through ice, clearing drain.

If nothing is blocking ager .. sounds like motor bad or something binding it up. If you took in out and cleaned all ice out and still dont work with no ice.. sounds like motor ..if it hums power is to motor
