Noise constant humming from inside set was told NO PROBLEM but is getting annoying

Hum is a constant low-frequency buzz, usually at about 60 Hz or 120 Hz, which results from voltage differences between true "ground" (what you'd get shoving a copper pipe into the ground) and the electrical "ground" of your receiver's chassis When this voltage differential exists, it's called a "ground loop," and the hum it produces is darned annoying. You'll hear the hum mainly from the subwoofer because it's a low-frequency noise, you will need a ground loop insulator they are about $20 at any electronic store

Which make/model do you have. If you bought a store brand ( Home Depot or Lowes ) it's a low-end Hunter. All you can do is take it back & get a new one and hope it's better. You can also try a fan control and see if that helps. Remember, you get what you pay for!

hi it could be a bad neutral connection on your plug or inside on your high voltage transformer check the plug for burning and try plugging it in a different socket

The constant humming noise you hear when the microwave is plugged-in but not running is caused by the Low Voltage Transformer, which is located inside the back wall of the outer cabinet on the left side. If the microwave is working properly otherwise, there is no hazard, just the annoying noise.

To access the transformer, the microwave must be taken down and the outer cover removed. The transformer is held to the back wall of the cabinet with four screws, and there are two sets of leads with pull-apart connectors. The noise is the result of 60hz vibration being transmitted to the sheet metal from the transformer which may not have been sufficiently "potted" or otherwise mechanically isolated when manufactured. You can either replace the transformer or try wedging some thin rubber or other material between the transformer and the sheet metal to quiet the noise. Just be careful to not damage the windings!

Hi,

This noise is most likely coming from the evaporator fan motor that is located behind the panel just below the ice maker. There is an air duct that the fan blows through to cool the ice maker that is why the sound is heard in the ice maker area more.

The noise does not hurt anything but the motor can be replaced if it gets too annoying, it is a fairly common complaint. The part number for the motor is WR60X10185 and runs about $60.00. It is a bit challenging to get to but can be done with a bit of patience by removing everything in the freezer and taking the back panel off the inside of the freezer.

I had this problem also on a different set top box (STB). What I did to get rid of that annoying humming noise was to unplug the RED plug only (from red, yellow, white combination) from the back of the STB, YEY!!! peace!!! This did not interfere with the picture or audio quality.

No no it is the noise of your hard disk ...as i have also same sound coming frm my laptop...

Mine does this too, just bought it yesterday and noticed the sound this morning, I guess because the house was quiet, now it's the most annoying noise ever. I have been searching for solutions all day, one forum said to go to the picture settings and turn the light sensor to "OFF"...Haven't gotten home to try it yet, but I hope this helps BOTH of us!

I purchased a poloroid tv 3732 in may of 2005 from circuit city, after about 14 months the set began making a clacking sound and humming sound that gets so loud it is unbareable. I have to turn the set off. I have found out I am not the only one with this problem that has a poloroid tv. I had a technician at my home that told me there is a service warranty on these sets because the wrong part was used and the part needs to be replaced.

you can test the cable from connection to connection for continuity from end to end. There should be no resistance( a complete short) If the cable is good, there is a bad or broken connection inside the mic. Good Luck
