Heat Issue


 

I bought my IC-7000 new 14 years ago and it always amazes me, but it has always had a heat issue.  I've always felt the need for an external fan. Without the fan, after receiving for a couple hours, the case get very warm, and on transmit, even on QRP CW, it get extremely warm (HOT) to the touch. The external fan keeps it cool, and the internal fan does work. Every so often I put the top cover off and blow out any dust, Watching a YouTube video a repair tech said the number one failure of the '7000 is heat related.  Yet a couple friends say their '7000 only gets warm, even at 100 watts.
Just wondering if anyone else here had same problems?

I've always felt that mine ran hot, but didn't really have anything to compare to. An external fan helped a lot.

Hi Curt, like you I also bought my 7000 new many years ago. At the time it was one of the first to hit the shores of Australia. I have had a few problems crop up over the years but most I would say were heat related or bad ribbon cables. The heat would get quite high if I left it idling on the bench for most of the day. It got to the stage where the radio was pretty useless (it would light up but nobody was home if you know what I mean), so in desperation,  I tried re-floating the large BGA type chips with an air solder station. The radio immediately came back to life and I have run it ever since with an external fan keeping it as cool as possible. The temp meter shows that it likes it and the radio has become extremely reliable once again. I can not say why some radios get hotter than others except to suggest that perhaps the conductivity between the ICs and their mounts is better on some radios than others.

Perhaps my radio came off the production line on a Friday - Hi.

Cheers,

Here's a thought. When Icom, or any other manufacturer, find a design fault in their equipment. They repair all under warranty and make changes to the design in the next production run. They never mention a word of this to anyone,of course.

My mine also ran warm to hot but found an external fan on eBay and never had an issue for over eight years.
