Excessive Fan Noise

I have owned my 42" Wega for almost two years and this past weekend the fan became noisy. I had never heard the fan before a couple days ago and now it is loud enough to be heard over the volume of the tv. How do I get the noise to go away and prevent it from returning in the future?

If I may - - the Grand Wega has a common color wheel problem and it may not be the fan at all... If while you are powered up listen carefully to the noise as you hit the power button - does the noise go away or is it still there? If rough noise stops and you can still here something in there running at a whisper then your problem is a bad color wheel not a fan... If it doesn't stop and it is the fan you'll most likely need to replace it.. Like Lemmor said you may need to clean your air intakes, which you can do with the hose on your vacuum but that is a brushless fan and no oil change in the world will help it..

Clean the fan inlets and outlets! if you could access for the bearing then put a pee amount of oil or grease on it ( enough amount only to lubricate it) clean also some heatsinks of your TV! some models trigger the fan speed to increase when internal temperature of the set increases.

Noisy fan and no heat


Kitchen aid is made by Whirlpool. There is a very good chance the then thermal fuse on the back of the oven has tripped. Whirlpools are very prone to this fuse tripping after a clean cycle. The noisy fan is just that a noisy fan it will probably need replacing. I have replace a couple of them over the years. When you pull the oven out to replace the thermal fuse replace the fan motor at the same tiome.

I have owned a Sony Grand Wega for about 3 years now and for the past few months the TV has been making a very loud noise. I thought the noise was the fan but came to find out it was not the fan and was...


Hello,

There is a fan beside the lamp chamber in this TV. There should be 4 fans total, and the one beside the lamp chamber might be making some noise. They are all bearingless fans, so the noise should be relatively low-pitched "whirr" if it is the fan. If the noise is more of a buzzing sound, it could be coming from the lamp driver (ballast) or from the lamp itself. Lamps tend to do strange things toward the end of their life.

If you have never changed the lamp, it is about time. They have a 2.5 -3 year life span with average use.

One thing you can try is to turn the TV on from a cold start, and watch inside the vent areas beside the lamp chamber. If you hear the noise before you see the lamp light up, then it is probably a fan. If it starts as soon as you see the lamp light up, it is the lamp or ballast.

Hope this helps you...

Sony 46'' WEGA TV


The mirror assembly has no moving parts, this unit has a minimum of 3 fans! if the fan blades get too dusty the fan will get noisy. Try cleaning the fans with compressed air.

Evaporator Fan Motor noise is excessive for this refrigerator. GE Profile CustomStyle Model PTI22SFMARBS Serial# SF900146V Jenn-Air


If the fan is always noisy, then it's probably is a bad fan. Easy to replace. But if the fan is quiet and purring sometimes, but buzzes like a demon when on high, then the problem is ice buildup. See a possible solution here.

Loud Fan Noise


This is a free repair on the optical block/engine. For specifically a road mapping issue. (Where there is sparactic grouped lines on the screen of the TV)

Otherwise there is a full recall on all 50XBR1's and 60XBR1's for ANY video issue.
But the bullentin I do have on that is Confidential due to the amount of claims SONY could recieve. But here is a sample of the bulletin.

Models: KDSR50XBR1, KDSR60XBR1

Subject: Optical Block: Warranty Policy and Part matrix by serial number.

Resolution: As part of Sony’s commitment to quality, Sony is announcing that it is extending the limited warranty (parts and labor) for optical block replacements on the models listed above until October 31, 2008, regardless of purchase date. Authorized servicers should follow the normal process for warranty claims for this issue.

Warm to Hot molding that seals the doors


Either the fan motor has gone bad or the coils under the fridge are too dirty. Both will cause a no cool situation and cause this area to become too hot. Part of the coil runs thru the cabinet in this area to prevent sweating. This is a good indication of dirty coils or a bad/weak fan motor. If your fan was noisy I would replace it before it goes out completely. This excessive heat will lead to premature compressor failure.
