Verizon DVR fan keeps running at high speed 24x7 now

So I've had this Verizon DVR STB for almost 4 years now. And for the past 2 days, the fan started running non-stop at its fastest and loudest rpm and it is running 24x7. 

There's nothing blocking the DVR and nothing has changed about it as such. 

All of a sudden the fan has kicked into high gear and has been doing that constantly. What is the solution to this? Do I need a replacement STB now?

My IMG was upgraded on 10/23, since then I have the same problem. Tonight I went to channel 1790 just to check it out, I was in shock the fan stopped! Once I tuned into a lower channel, it resumed. There have been other postings stating the same problem, evidently it's a known issue that's been occurring for years! Verizon needs to address and fix this, the noise is so annoying!

You need to have the STB replaced. Once the fan begins to do that it will eventually fail.

My DVR also started running (sounds like the fan) all the time. I saw other posts that said changing the LED display on the box could help. I did that and it did help me (for now).  You might try the following:

Using your Remote Control, go to Menu, Settings, System, Set Top box, LED Brightness, and change the setting to Low. 

Hope this helps.

But as others have said, it is only a matter of time before the box fails.

Fan speeds up as temp increases.

Couldn't hurt to make sure all the vents are clear.
