Hello friends, I have a 370 liter RI480 indurama refrigerator with 1 year 1 month of use (no longer guaranteed) and for a few weeks, when the freezer starts working (only in certain cycles) a squeal sounds (like cable with cable making contact) in the cold regulator (where the numbers from 1 to 5 come out) I have tried connecting it directly to the outlet, with a space voltage protector for refrigerators (Nicomar for refrises up to 856 liters) and the problem is the same. The truth is that the refrigerator cools down normally, freezes well, but it is that screech that causes interference on the television and on my son's baby monitor, which has me worried ... I recorded a video to better explain the problem .. . Thanks for helping!!'
