NO AUTO FAN ON KPA-1500

I have a KPA-1500 SN 329 that is working great.

However, when the temp goes above 40C the fans do not come on the amp unit
like they used to.

I reloaded firmware 02.38 to see if that helped. It did not.

However, when I run the KPA1500 Remote software I can run the fans from
there ok. Just not in the MIN FAN: AUTO mode. I can click and start each
fan, so I can keep the temp under control.

BUT, in the AUTO mode they never start.

Sounds like a defective temp sensor.

FW: NO AUTO FAN ON KPA-1500

In reply to this post by KENT HUFFORD

Yes, Larry, I found your great program, and using it instead of the Elecraft KPA1500 Remote software. With your program it reads the WORKING Temp sensor in the amp and increases the speed as required automatically.

With the Elecraft KPA1500 Remote software, it also reads the WORKING temp sensor, but you have to manually increase the speed as you want.

STILL does not fix the issue within the amp of not automatically increasing the fan speed as the temp goes up.

Thank you for your program. Great stuff.

You could use the freeware FANticipator app for fan control.

Re: FW: NO AUTO FAN ON KPA-1500

Funny, my 1500 increases speed with increasing temp. Above 70C it's
quite the howler.

NO AUTO FAN ON KPA-1500

In reply to this post by KENT HUFFORD

Just a couple of questions:

If the temperature sensor isn't working how are you measuring the temperature?

What is the highest observed temperature with fans not running?

The temp sensor is working. The remote software sees the temp. And I can
control the fans with the remote software.

48c. Then I turned on the fans with the remote software.

When the auto temp feature in the amp working, the first fan came on at
about 40c

Yes, that’s what mine has done for 2 years.

BUT, the fans do not come on when the temp goes up, except with the PC programs.

Re: NO AUTO FAN ON KPA-1500

In reply to this post by KENT HUFFORD

The turn-on temperature for fan speed 1 is 50 degrees C. Fan speed
threshold temperatures are in the KPA1500 firmware release notes for version
1.87.

In earlier firmware, the fans did indeed come on at less than 50 degrees C.

What is the highest observed temperature with fans not running?
