1. My fridge is making a loud clicking noise at

I bought the same model and it made the same clunking noise you describe. I replaced it and the new one made exactly the same noise. For those of you at fixya this is not a constant noise; it is intermittent and very loud. It sounds like someone hitting a large pipe against metal. This is perplexing.

Ah the bottom. The drain pan is overfull and can not Handel the amount of water going into it. Normal running operation will evaporate any water left in the pan. You can pull out the fridge and drain the pan or clean up the water until it stops. Good luck

The freezer compartment fan may have Icing or the motor is going.....Remove the trays and remove the rear cover. The fan and Freezer evaporator are behind that cover.
The fan doesn't run all the time.


If you have an ice maker it too can make buzzing sounds. Just turn off the Ice maker to eliminate it as a source.

Here's a link to the service manual for the 215

Problems not related.  The first is most likely the fan, or possibly water dripping on to the fan and freezing, but usually the noise comes from the fan struggling to run.  The cube problem could be as simple as the ice dispenser being put back in wrong.  There is a metal lever under the ice tray that switches between crushed and cubed.  Make sure it is seated properly.

I have one of these, and every so often, the fan would start making a loud clicking noise. I discovered that if I shut the fridge off for a while and left the door open to defrost it, it'd work fine again for a while before the noise came back. Apparently, some ice was building up between the metal heat-sink and the fan, causing the fan blades to scrape against the ice/frost build-up and make the "tick, tick tick" noise.
There is no compressor in the Avanti EC15W-2 mini fridge. It uses a simple Peltier junction device to transfer heat from the inside of the fridge to the outside/rear of the unit. So it should never get very loud at all, unless one of the two fans in it is acting up in some way.

check fan at the back of refrigerator or you have defrost problem

if you have ice buildup then the fridge may be low on freon.
or there is dust clogging around the pump or fan is not running.
remove the bottom or back and look around the compressor.
see that the fan is running.

The middle part of my refrigrator (RS21DCNS) is full of ice. i have removed ice many times. could you tell me whats the reason and solution of this?

Hollow ice cubes are due to low water pressure to the fridge. Water thru the door should have good pressure behind it. This is a good indicator of water pressure. Should be able to fill a glass quickly. Causes for low pressure are self-piercing saddle valves on the water line (switch to drill type (1/4") valve) or reverse osmosis system or filtering system on water line to the fridge. R.O. systems should not be used. Increase water pressure and that will fix the hollow cubes. The loud noise may be the sound of the water valve on the fridge when it is acivated. This sound is normal and some are louder than others.
