<!-- from fixya rte -->Loud noise from back of refrigerator - Igloo Cooler Igloo 3.2 cu. ft. Refrigerator and Freezer

if the fan is still running when you open the door , the I would be leaving that idea as a last resort
try this
get 2 taper door chocks and put one either side at the back of the fridge
push the cabinet sideways and slip one chock in a bit then do the other side
many noises are from the bottom plate that the compressor is mounted on from tapping on the floor and lifting it a bit stops the noise
the same as when you open the door the pressure on that plate is removed and so it stops hitting the floor

Hello David;

My name is Peter. I am a retired field service refrigeration technician.

The noise is coming from one of two places.

1.) Freezer Fan - The fan may be hitting ice. After defrosting the noise will disappear.
2.) Compressor Flapper Valves - Remove the cover to expose the compressor. Plug the unit back in. If the compressor starts jumping unplug the unit. Check the rubber bushings where the compressor is bolted down. Are the bolts loose? Is the rubber torn off? If the compressor is secure, then you have a bad compressor.

Your refrigerator has at least three motors with fans in addition to the compressor motor. The one most suspect is the one that passes air from the freezer to the refrigerator.

That's the icemaker cycling.Ifya don't have water connected,it's still think'n its filling trays and dumping frozen cubes and all that stuff.Turn off the icemaker.Rigger said that.C-YAAaaaaaaaaaaaa

Check the condenser fan (outside at the rear) and check the coil isn't baking hot. Electronics or board wouldn't cause your symptoms. Check the simple things first!

Is it coming from inside the freezer or outside? If outside either the auto defrost timer is a problem. If the noise comes from the compressor, almost certainly the starter relay inside the electrical cover needs to be replaced. It can be purchased at most refrigeration outlets. If coming from inside, you need to defrost the freezer properly for 12 hours then restart. The noise should go away then.

Locate what is making the noise. There is a fan in the freezer behind the rear cover inside. There is a fan underneath accessed from the rear behind the cardboard backing. The compressor is also there with a starter/overload relay which could make the noise.

please switch off your refrigerator for at least 8 hrs. than again switch it on. if your problem is not cured than it is sure that your refrigerator have the blower problem because for this reason only, the problem arrises ....... please visit your service authority...........have a nice day:-)

This could be just the refrigerant feeding through the system which would be a normal condition. If the temperatures maintain the system is doing its job.
