Just bought mine today and turned it on 4. Every several minutes the fan will decrease for a second and then go back to normal. It's almost like a power issue, but I don't notice lights dimming or anything else other than the fan noise for that...

I would check the wall receptacle for loose plug in or wire connections. If they are Ok and you don't see any other items dim in power, than I would suspect the Holmes unit to be defective. I would ask for a replacement from Amazon right away, it could cause a fire. So could the other items mentioned. Good luck

So I used this ballast and then replaced all cooling fans...tv would still shutdown due to heat on occasion...really frustrating...never had a problem turning it on...moved the TV to another room...and the problems have ceased...weird...

I think that is when it goes into it's "high power mode" every once in a while. You can try turning it to low, but mine works way better/faster when it is on high. It gets annoying if you are sitting next to it and watching TV, so maybe put it in a different room and move it back when you are done?

Mine is always on with no load as well but also pretty quiet. It will ramp up a lot under load. I don't find the no-load noise too much but under load it can be pretty loud.

I've had mine since February 2013 and can't say the fan is loud. I have had issues with it freezing up and having to reboot though.

I received mine today (2/7/14), plugged it in and it worked fine. Turned the dimmer switch off and it never turned back on again. So... apparently it is still an issue.

Mine did that initially. Up and down between 49 and 53 and the fan kicking in every couple of seconds. I raised the temperature to 55 and it stopped doing that.

Is there any confirmation from the manufacturer that the fan should be always on or not?My fan does not running at all when I charge my battery. Really afraid that the charger could be getting to hot or burnt out...

In my case the fan was only running on one speed but the light worked. I took it apart and found this part had a burnt spot. I replaced it and everything has worked fine. Good luck

Hello Jerseyboy.The fan is a tiny bit noisy, as in you can definitely hear it. But its really hardly noticeable. The only time I notice the fan is when I first turn it on. but after the sound kicks in, you hafto struggle pretty hard to hear it. J. FisherReplicasUSA

Make sure the fan is not blocked with dust and is working, Mine works fine after I removed the plug on the end and wired it directly to the outlet. I went through 3 of these in 6 months but removed the plug and it works like a champ.

My fan only has one light ... the up light button and the down light button do the same thing (turns on, turns off and hold to dim)

Sorry. I got a defective fan and so returned it. Didn't run it for anywhere near that length of time.

Yes mine does the same thing. My guess is that my fan wore out because the first few days it was loud and annoying, but eventually stopped. Only then did my computer begin to overheat and shut off when I play certain video games for as little time as 45 minutes.
