Is is the sound of water being thrown around? Some units actually sling the water from the drain pan back onto the coil. This improves efficiency. It's sort of a gurgling sound. Here's more helpful information is you need it:

mINE IS DOING EXACTLY THE SAME - I'VE HAD IT ABOUT 2 WEEKS BUT ONLY STARTED MAKING THIS SOUND TODAY AND AS YOU SAY ONLY WHEN THE FRIDGE DOOR IS OPENED AND THEN SHUT!

This is normal when compressor starts u can hear some gurgling from evap. from feron flowing. If you hear gurgling only when you close the door it's water in drain pan when you close the door air is forced down drain tube blowing air into water.

The gurgling sound , is the vacuum being pulled thru the defrost drain line . Like when you close a freezer door , and you see the gasket being pulled in tighter . This gurgling , is the drain p trap with a vacuum being pulled thru it . Normal .

gurgling is not unusual and is caused exactly by fluid bubbling thro a pipe.

Possible that door has been left open a few weeks ago, sollution, turn off defrost overnight with the doors open, turn on following day, unit will work ok within 24hrs. Regards Advisor

Hi Andy, I have had luck insulating the cap tube coming off the heat exchanger, going into the evaporator. If the repair man can wrap some mastic around the area where the cap goes into the evap, this may quiet it down enough. This is common on some models. Some people are more in tune to it than others. Give that a try. Catriver.
